7 best truck gps for semis (October 2026) Honest Reviews

The best truck GPS for semis right now is the Garmin dezl 580 LMT-S, a 5-inch dedicated navigator with 2747 owner reviews and free lifetime map updates, and the strongest runner-up is the Garmin dezl OTR800 if you want an 8-inch screen and load-to-dock guidance. Both plan routes around your rig’s height, weight, and length, so a 53-foot trailer never gets pointed at a 12-foot-4-inch underpass. This roundup covers 2026 and was last checked in September 2026.

A car GPS, or a phone running plain navigation, has no idea what your rig weighs or how tall it is. It will happily send a loaded truck down a restricted county road, through a low-clearance bridge, or onto a span closed to hazmat. One bad route costs far more than the device itself: a citation, a damaged trailer, hours of drive time burned on a detour, and fuel. That is why a dedicated truck GPS still earns its place in a semi cab even when phone apps have gotten good.

We put seven dedicated in-cab units through the same filter: truck-specific routing that reads your profile, brightness and readability in direct sun, how the unit holds a mount through washboard roads, and what the map update policy costs you over the years you plan to keep the box. Every rating and review count below is copied straight from the product listing, and every con line comes from what owners report back. Where the market only offers thin options, we say so instead of padding the list.

One framing note before the picks. This category is dominated by two brands, and it is a duopoly in the practical sense: Garmin dezl on one side, Rand McNally TND on the other, with very little credible third-brand truck hardware in the mainstream channel. We reviewed what actually exists in this lineup rather than padding to ten slots with near-duplicate generic boxes.

Top 3 Truck GPS Picks for Semis in 2026

If you want the short answer before reading further, these three cover the realistic choices. The dezl 580 LMT-S is the safest default, the OTR800 is the premium pick, and the OTR610 is the version to buy when arrival planning matters more than raw screen size.

Best Truck GPS for Semis in 2026: Quick Overview

All seven devices in this roundup, side by side. The standout column is the feature that actually changes daily driving rather than a spec-sheet line.

1. Garmin dezl 580 LMT-S – The Most Proven Truck GPS for Semis

This is the unit we keep coming back to, and the reason is dull but decisive: volume. At 2747 owner reviews and a 4.4 rating, the dezl 580 LMT-S has more real miles behind it than anything else on this list, which means the bugs have mostly been found already. When a routing engine has this many owners, the failure modes are documented rather than mysterious.

Day to day it does the core job well. You set your truck profile once, and the unit plans around it, warning you about upcoming bridge heights, weight limits, and sharp curves before you get there. The truck and trailer services directory is filterable by brand or by amenity, so finding a shower or a specific stop is a couple of taps instead of scrolling.

Two extras matter more than they look on paper. Up-ahead road signs surface upcoming exits with nearby restaurants and rest areas, and the break planning notifications keep you ahead of your hours of service clock instead of reacting to it. Combined with free lifetime map updates, the running cost of this box is effectively zero after the sticker, which no other major-brand option in this lineup can say.

The hardware dates from an earlier generation and it shows in the details. The display is 480 x 272 on a 5-inch panel, which is fine for a straight highway read but tight at a stacked cloverleaf. Measured at 5.9 by 1 by 3.7 inches and 8 ounces, it is also the easiest box here to find a home for above a visor or on a B-pillar mount in a tight sleeper.

Battery life is listed at 2 hours, so plan on it living on the truck power cable. Connectivity is Bluetooth and Wi-Fi, and the 16 GB of internal storage is what carries the map updates. Connectivity protocol listed as Bluetooth and Wi-Fi means you can pull new maps over a truck stop Wi-Fi network instead of waiting for a USB update at home.

Who the dezl 580 LMT-S suits

Long-haul owner-operators who want zero recurring cost. If you keep a truck five years or more, free lifetime map updates alone make this the cheapest navigation per mile in the group, and the 4.4 rating across 2747 reviews suggests the routing holds up.

Drivers who share a cab with a passenger or run a second screen. Voice control and Bluetooth hands-free calling mean the unit is not a touchscreen-only device you have to lean toward, and the small footprint leaves windshield space free.

Where the dezl 580 LMT-S falls short

Clutter at complex junctions. A 5-inch screen showing a five-lane interchange with a split ramp is the one scenario owners mention most, and if your route is dense city work rather than open interstate, step up to the 6-inch or 8-inch Garmin.

Address search is imperfect. Entering a dock address with a building or unit number can fail to resolve, so verify the destination pin before you commit to the last miles. Speed limit data also occasionally disagrees with the posted sign, so treat it as a prompt, not an instruction.

2. Rand McNally TND 550 – A Low-Cost Real Truck GPS Entry Point

The TND 550 exists because a lot of drivers want a real truck navigator without a real truck budget. It runs Android, has a 5-inch 480 x 854 capacitive touchscreen, and ships with the truck features you actually need on day one: truck-specific points of interest and multi-trailer profile support. That last item is genuinely useful if you swap trailers often.

Real-time traffic and dynamic weather overlays are included, which is unusual at this end of the market. The 3D junction views and 3D buildings are a real aid in unfamiliar cities, and at 4.4 ounces and 1 by 5.25 by 3 inches, it is the smallest and lightest box in the roundup. Rated battery life is 5 hours, the longest stated figure here, so it survives a short regional run unplugged.

The weakness is reliability, and owners say so plainly. The 3.8 rating across 432 reviews is held down by reports of the unit freezing up mid-trip and dropping navigation on the final stretch of a route, which is the exact moment you can least afford it. Touch targets are small and finicky to hit while the truck is moving, and maximum audio volume is described as inadequate in a loud cab.

Map currency is the other recurring complaint. Missing streets, absent truck stops, and long-term construction zones that never update will all be reported. There is also a cluster of long-term users describing one to three years of durability and bookmark loss after firmware updates that required factory resets, plus support described as unresponsive when things went wrong.

Storage is 2 GB internal, warranty is one year limited, and mounting is a heavy-duty suction cup. The suction cup is a real concern in a semi cab running washboard sections, and it is the single cheapest upgrade you can make by moving to a RAM-style ball mount instead.

Who the TND 550 suits

New CDL holders and regional drivers building a first dedicated unit. It is a low-cost way to get real truck-specific routing with traffic, weather, and multi-trailer profiles, and the 3.8 rating reflects the compromises rather than a failure of concept.

Anyone who changes trailers daily or runs short regional loops where a 5-hour unplugged battery is genuinely useful. You also get the Rand McNally truck data set, which drivers consistently credit for road construction and weight station detail.

Where the TND 550 falls short

Do not rely on it for hazmat or oversize routing precision. The data set is thinner, and stale construction information is a compliance problem, not just an inconvenience, when your load is restricted.

Expect interface friction. Small buttons, occasional freezing, and firmware updates that wipe custom bookmarks add up over a long haul. If you can stretch to the 6-inch Garmin, the smoother experience is worth the step up.

3. Garmin dezl OTR610 – Best for Docks, Yards, and Tight Arrivals

The OTR610 is the one to buy if your route ends in a yard you have never seen. BirdsEye satellite imagery lets you look at the destination from above before you arrive, so you can see the loading dock, the truck entrance, and the security gate layout rather than circling the block. On drop and hook work, that alone can save ten minutes of idling every single delivery.

Underneath, the routing is the same solid truck profile Garmin uses across the line, with alerts for bridge height, weight limit, sharp curve, and steep grade. The 6-inch multi-touch glass HD color TFT panel runs 1280 x 720, which is a genuine step up in legibility from the 580, and the whole thing weighs 6.17 ounces at 6 by 0.7 by 3.4 inches, so it stays out of the way on a dash mount.

The route planner is more than a map here. It reviews your full route and lets you pick fuel, comfort, and overnight stops, then folds them into the plan. On top of that, the truck and trailer services directory filters by brand or amenity, and PrePass weigh station and bypass notifications arrive through the dezl app when you have an active PrePass account. Love’s and Pilot loyalty points come in over Bluetooth the same way.

Map coverage is integrated North America, covering the U.S., Mexico, Canada, the U.S. Virgin Islands, and the Cayman Islands and Bahamas, with updates handled over Wi-Fi. It also pairs with BC 50 backup cameras, a dezl trucking headset, and a dezl Edition smartwatch if you already own Garmin accessories. Storage is 16 GB and warranty is one year limited.

The two real frictions are setup and input. Address entry defaults to a same-city search and has been reported routing a driver to a distant state, so double-check the destination before you leave the yard. Owners also mention occasional lag, glitches, and interface slowdowns, and the 6-inch display is bright enough to read at a glance in direct sun.

Two hardware notes. There is no internal battery, so the unit depends on vehicle power whenever it is unplugged, and there is no built-in option to avoid tollways with few alternative route choices offered. If your lanes cross toll bridges regularly, that is a real planning cost you will absorb in routing time.

Who the OTR610 suits

Dock-to-dock and drop-trailer drivers where the last half mile is the hard part. The BirdsEye arrival preview is the single most useful feature on this device for anyone who has argued with a security gate at 6 a.m.

Drivers who want a 6-inch screen without moving to the 8-inch OTR800. At 961 reviews and 4.3, this is a well-proven middle step, and it is also the pick for anyone running PrePass and travel center loyalty programs daily.

Where the OTR610 falls short

The address entry flow is unintuitive and the most common frustration. Budget thirty seconds on every new stop to confirm the state and city, especially on multi-stop days.

No internal battery and no toll avoidance. If you run urban lanes with toll routes or plan to pull the unit into a truck for a walkaround, this is the wrong box.

4. Garmin dezl OTR800 – Most Versatile With Load-to-Dock Guidance

The OTR800 carries the highest rating in this group at 4.5 across 649 reviews, and the reason is the screen. Eight inches of 1280 x 800 color TFT is a different experience when you are reading a lane assignment at 55 mph or parsing a five-lane interchange exit. Owners point to the display first in almost every review.

The headline feature is load-to-dock guidance, which shows potential loading zones or storage lots as you approach the destination. It is a deeper cut than the BirdsEye imagery on the OTR610: instead of an aerial view, you get the operational answer, where the trailer is actually going to sit. For dedicated and dock-to-dock work that removes most of the yard wandering.

Truck-friendly parking information runs along the route, and popular routes from fellow truckers add a layer of situational awareness in areas you do not know. The truck and trailer services directory is preloaded, and the voice assistant covers hands-free operation so you are not tapping the screen at every exit.

Mounting is the most complete option here: a powered magnetic mount with heavy-duty suction cup, a screw-down mount, and a 1-inch ball adapter with AMPS plate. On a semi cab that vibration tolerance is worth more than it sounds, because a suction cup that walks loose at 60 mph on broken pavement is the most common complaint in this whole category. The unit weighs 13.6 ounces and measures 11 by 6.9 by 3.6 inches.

One integration is easy to overlook. The OTR800 works with a Garmin eLog compliant ELD, sold separately, to record hours of service without a subscription. Drivers paying a monthly fee for electronic logging in every other unit should notice that line item, because compliance cost is usually larger than navigation cost over a year.

The trade-offs are physical and predictable. This is one of the bigger boxes in the lineup and it takes real dash space, which some drivers consider too much even in a semi. Battery life is listed at 2 hours off vehicle power, and route recalculation has still sent drivers around infrastructure changes in a few reports. Street-level map accuracy and address search can also miss on new construction.

Who the OTR800 suits

Dedicated and dock-to-dock drivers who are paid by the hour. Load-to-dock previews reduce yard search time, and at 649 reviews with a 4.5 rating the feature set is proven rather than experimental.

Owner-operators who want compliance handled in the same box. Pairing with the Garmin eLog ELD removes a subscription from the running cost, and the 8-inch display cuts glance time on dense metro approaches.

Where the OTR800 falls short

It is a big box. If your dash is already crowded with an ELD screen and a reefer controller, measure before you buy. The 8-inch panel blocks more of the windshield than any other option here.

Unplugged use is short. Two hours of stated battery means it is a permanently installed device, and that is fine as long as you plan it that way from day one.

5. Rand McNally TND Tablet 85 – Best Built-In Dash Cam in the Lineup

This is the renewed version of the TND Tablet 85, and the reason it earns a place is the integrated dash cam. Having a forward-facing camera already in the navigation box removes a separate device, a separate mount, and a second power lead in a cab that has no room left. Owners cite incident documentation and inspection reports as the main draw.

The navigation underneath is the Rand McNally 2.0 platform with real-time traffic and construction updates that work even in rural areas, plus dynamic weather overlays showing precipitation, temperature, and wind speed. That rural construction layer is a genuine advantage when your route crosses states where closures move week to week.

It also does the small fleet admin things that add up: current fuel prices along the route, mileage and fuel logs for economy tracking, and on-screen alerts for speed limit changes and sharp curves. For an owner-operator watching cost per mile, having the fuel log in the same device as the route planner removes a step.

The screen is 8-inch LCD with 3D buildings and landmarks for city situational awareness, and it runs Android with 2 GB of internal storage. Connectivity is Bluetooth plus USB and wireless, and the box in the case includes a powered magnetic mount, truck charger, USB cable, and wall charger, so it can live on a desk when it is not in the truck.

Be clear-eyed about two things. The 480 x 272 resolution is genuinely low for an 8-inch panel, and text and lane detail look soft next to the 1280 x 800 screens in this roundup. Renewed stock also means you are buying a device that has already been in service, with wear that may or may not be visible.

The warranty is 90 days limited, against one year on the new models, and that is the main risk to weigh. At 4.0 across 157 reviews the feature set is well regarded, but the review base is small and route recalculations are occasionally reported sending drivers the wrong way. Treat it as a value play on the dash cam, not on the routing.

Who the TND Tablet 85 suits

Owner-operators who want dash cam footage without another wire or mount. Integrated footage, fuel logs, and navigation in one 8-inch box is a tidy solution for a single-driver operation.

Drivers on routes with changing rural construction. The real-time construction layer and the fuel price display are the two features buyers actually mention first.

Where the TND Tablet 85 falls short

Renewed means renewed. Ninety days of warranty is a real difference when a unit lives in a truck, and the low native resolution undercuts the benefit of the large panel.

Navigation is not the strongest part of the package. If routing accuracy is your primary job, the Garmin options route more confidently for the same class of money.

6. LOVPOI 9-Inch Truck GPS – Budget Pick With a Bigger Screen Than Most

The LOVPOI A9 is the only way on this list to get a 9-inch screen, and that size alone solves a real problem: glare and reach. A larger panel is easier to read at a glance and easier to hit with a gloved hand on a bumpy road, and the 800 x 480 resolution holds up better than the entry-level norm even if it is well short of the Garmins.

It is not a toy, either. Custom routing accounts for truck size and weight with bridge height and weight limit alerts, and the voice alerts cover dangerous curves, speed changes, speed cameras, railroad crossings, and animal crossings. Maps cover the USA, Canada, and Mexico with free lifetime updates, which is the same long-term cost story as the dezl 580 LMT-S.

Two details make it more useful than the price suggests. There are over 40 selectable voice guidance languages, and an FM audio transmit function that boosts navigation volume through the truck’s own speakers, which directly answers the quiet-audio complaint that drags down other budget boxes. It also has multiple vehicle modes including semi truck, ambulance, bus, and taxi.

Storage is 8 GB internal with microSD expansion, connectivity is USB, and the box includes a satellite navigator, car charger, USB cable, suction cup mount, back bracket, and user manual. Dimensions are 8.66 by 5.31 by 0.79 inches. The one year warranty is standard for the category.

The 3.6 rating across 1095 reviews is the honest part. Owners report routing accuracy and map currency lagging behind the Garmin and Rand McNally devices, and build quality and interface polish are consistently described as below the premium devices. That gap matters more for hazmat and oversize work than for dry van regional hauling.

Setup is also clunkier than it should be. Adding non-North American maps can require a Windows PC or a TF card process rather than a wireless update, and satellite lock can be slow to acquire indoors, which will frustrate you during pre-trip inspection in a yard. Battery life is listed at 2 hours.

Who the LOVPOI 9-inch suits

New drivers building a first navigation setup on a strict budget. You get truck-specific routing, bridge and weight alerts, and lifetime map updates for a fraction of what the branded boxes cost.

Regional and local haulers running tight urban streets where glare and a big readable panel matter. The 9-inch screen is genuinely useful at low speed in city work, and the multi-vehicle modes cover mixed fleets.

Where the LOVPOI 9-inch falls short

Do not run restricted loads on it. Stale routing data on a hazmat or oversize profile is a real compliance exposure, and the interface polish is not there to bail you out.

It is a navigation box, not a fleet tool. No ELD pairing, no load-to-dock guidance, no dash cam. If your operation needs any of those, the money is better spent one tier up.

7. Rand McNally TND 1050 – The Biggest Screen You Can Put in a Cab

Ten inches is the top of the in-cab market and it exists for a reason. At 1280 x 800 the TND 1050 gives you the biggest, sharpest map you can mount in a truck, and owners consistently point to the reduction in glance time. Every second your eyes are off the road is a second, and this is the most extreme way to cut it.

The build is unusually serious for a nav unit. The screen is Gorilla Glass with a removable protective guard, which is exactly what you want on a dashboard that takes road vibration and winter grit. Rand McNally also claims 33 percent more truck-specific road data than other GPS providers, and with three mounting options, a powered magnetic dock, a ball mount bracket, and a windshield suction cup, you can pick the one that suits your dash.

The integrated dash cam handles driver and vehicle inspection reports, and receipt tracking keeps expense records attached to the trip rather than in a shoebox. Connectivity is Bluetooth 5.0 with Wi-Fi, charging is USB-C, and updates happen over Wi-Fi without a laptop. Android underneath with 32 GB of internal storage is the most headroom of any device here.

Battery life is listed at 5 hours, tied with the TND 550 for the best stated figure, so it can genuinely be pulled out of the truck and used away from power. At 10.5 by 6.5 by 1.2 inches and 1.8 pounds, it is also the heaviest, and that matters if your mount is not rigid.

Size is the trade-off owners argue about most, and it is not small even for a semi. A 10-inch panel on a windshield takes a real amount of visibility, and drivers on tight regional lanes often find it more obstruction than help. The removable guard helps, but it does not shrink the footprint.

There are routing quirks too. Map orientation issues can send drivers backward for a nearby stop, arrival time and traffic estimates are not always accurate, and the software produces spurious railroad crossing warnings near interstates that have no crossing. At 4.1 across 199 reviews, the feedback base here is the thinnest of the Garmin options, so buy with that in mind.

Who the TND 1050 suits

Long-haul drivers on open interstate who want maximum readability and a rugged panel. Gorilla Glass plus a removable guard is the right build for a truck that lives outside, and the 5-hour battery makes it the only large-screen option that is genuinely portable.

Owner-operators who want inspection evidence and expense records handled in the same box as the route. The dash cam and receipt tracking cover the two admin headaches that generate disputes after a trip.

Where the TND 1050 falls short

Measure your dash before ordering. If the mount is a suction cup and you run rough pavement, the magnetic dock can loosen over bumps and potholes, and at 1.8 pounds the leverage on a loose mount is significant.

Mind the software quirks before you trust it with a tight delivery window. Inaccurate ETAs and orientation errors are frustrating in a way that routing errors on a rural highway never are.

How to Choose a Truck GPS for Semi Trucks

Buying a truck GPS is mostly a matter of matching the hardware to your lanes, your rig, and how long you plan to keep it. Six factors decide nearly everything, and none of them are the headline screen size.

Screen size and semi cab fit

Screen size is a readability decision first and a spec second. Five inches is workable on open highway and cramped at dense interchanges, six inches is the comfortable middle, and eight to ten inches is a genuine aid in city work where lane guidance and close turns matter. Ten inches is also the point where drivers start reporting that the unit blocks useful windshield space.

Measure your dash before ordering, and check where your ELD screen and any reefer controller already sit. A 9- or 10-inch panel next to an ELD is a real visibility cost. If you are also buying interior protection for the sleeper, our truck seat cover guide covers the rest of the cab setup.

Map update policy and five year cost of ownership

The single biggest cost difference between brands is not the device, it is what happens in year two. A dedicated unit with lifetime map updates costs nothing to keep current, while subscription-based traffic and weather services add an annual fee for as long as you own the box. Over a five-year ownership horizon that gap is larger than the price difference between most models here.

Ask three questions before you buy: are the maps current for life, does the traffic and weather layer require a subscription, and does that subscription cover the units in your fleet or each device. If you are not sure how the math works, the marine GPS buying guide covers the same lifetime-map-versus-subscription trade-off from a different angle.

Mounting and power in a semi cab

Suction cups fail, and they fail on the worst possible road. Any semi cab running washboard sections, chip seal, or badly patched interstate will eventually shake a suction cup loose, and a 1.8-pound tablet coming loose is a genuine safety issue. Prefer a ball adapter with an AMPS plate, a screw-down mount, or at minimum a powered magnetic mount with a heavy-duty cup.

On power, plan on constant 12V or 24V truck power rather than the cigarette lighter port, and use a fused line so a wiring problem does not take out the cab circuit. Note the stated battery figures across this roundup, which run from about 2 hours to 5 hours, and treat every one of these devices as installed equipment rather than a handheld.

Hazmat and oversize routing modes

If you haul hazmat, tankers, or oversize loads, the routing profile is the whole game. A unit must let you set cargo type and be able to exclude restricted roads, not just weight and height. Owners consistently credit Rand McNally with strong truck-specific data, including road construction and weight station detail, while Garmin is credited with routing accuracy and interface polish.

Verify the profile fields before you rely on them, and run a test route through a downtown area you know well. If your operation runs five or more trucks, standalone navigation units usually give way to platform systems like Motive, Samsara, or Trimble, and that is the point where the buying decision stops being about a GPS at all.

Dedicated truck GPS or a trucker app

An app is cheaper and easier to update, and most good trucker apps route properly. The reason drivers still buy hardware is the failure mode: free-tier apps depend on cell coverage, and coverage dies exactly where you need a reroute, on a mountain pass with nothing loaded but a browser.

The practical answer most drivers settle on is both. Run a trucker app for community-reported parking and truck stop availability, keep a dedicated unit for the route itself. On a physical device you also get CAT scale locators, diesel lanes, and truck stop POIs without a data plan. If you want the app option covered in depth, our handheld GPS guide compares offline-first hardware in a different format.

Garmin dezl or Rand McNally TND: Which One Should You Buy?

If you have narrowed the field to the two major brands, the honest answer is that Garmin wins on routing accuracy and interface polish while Rand McNally wins on truck-specific data depth and long-term update cost. Here is how that splits in practice.

Routing and truck data

Garmin routes more confidently. Drivers on r/Truckers describe it as the best for routing accuracy without qualification, and the recurring consensus is that the dezl line rarely produces a route you have to second-guess. That reliability is what makes it the default pick for long-haul and hazmat work.

Rand McNally is valued for a different thing: the depth of the truck data itself, particularly road construction detail, weight station information, and multi-trailer profiles. If your operation runs oversize loads or drops trailers frequently, that data advantage can outweigh a cleaner map.

Map update cost over five years

This is where the two brands genuinely diverge. Garmin positions traffic and weather through the dezl app, and a subscription for that layer is a recurring cost across the life of the unit. Rand McNally units in this lineup carry lifetime map updates with no recurring fee, which is the single most-cited reason drivers move between brands.

Run your own numbers before deciding: device outlay plus annual service multiplied by the number of years you expect to keep the rig. Over a five-year horizon, and across several boxes at once, the difference is meaningful enough to change the decision on its own.

Interface, support, and firmware

Garmin’s interface is the more polished of the two and the easier one to hand to a new driver. The recurring Garmin complaints are input related rather than routing related: address entry that defaults to a same-city search, occasional lag, and speed limit data that occasionally disagrees with the posted sign.

Rand McNally’s complaints lean harder on reliability and longevity, with freezing, outdated maps, small touch targets, and a cluster of reports of firmware updates wiping bookmarks and requiring factory resets. Support responsiveness is also described as slower. Both brands carry a one year limited warranty on the new devices, with the renewed TND Tablet 85 the exception at 90 days.

Whichever cab you sit in, plan for the rest of the rig. Our truck bed toolbox guide covers the equipment that stays with the trailer, and our highway truck tire guide covers what is actually between you and the road.

Frequently Asked Questions

The Best Truck GPS for Semis in 2026

The best truck GPS for semis is the Garmin dezl 580 LMT-S. It holds the highest combined rating and review volume in this roundup at 4.4 across 2747 owners, its routing respects your rig profile, and free lifetime map updates keep the running cost at zero for as long as you own it. That is the pick for a long-haul owner-operator who wants one box that just works.

Buy the dezl OTR800 instead if you are paid by the hour and the last half mile is where your time goes, because load-to-dock guidance and an 8-inch display remove the yard search. Choose the dezl OTR610 if arrival planning is the problem you actually have and you want to stay at 6 inches. The Rand McNally TND 1050 is the answer for sheer screen size and rugged build, and the LOVPOI 9-inch unit is the honest budget pick when the outlay has to be small.

One last filter before you order: budget, screen size, and whether you need a dash cam or ELD pairing. Answer those three and the shortlist is already made for you. Then power it from a fused truck line, mount it on a ball or screw-down bracket rather than a suction cup, and spend ten minutes confirming the address on your first live route.
