Our Verdict

The Garmin Dezl OTR810 wins for North American trucking with its larger screen, better truck-specific routing, and Garmin's strong trucking ecosystem. When routing accuracy means the difference between a smooth delivery and a stuck truck, Garmin's data is worth the premium.

The TomTom GO Expert Plus wins for drivers who prioritize traffic avoidance and voice control. Its traffic data is genuinely superior and the price is more accessible.

For US-based truckers, the Garmin is the safer choice. For drivers who also run into Canada and Mexico regularly, TomTom's broader coverage is worth considering.

Frequently Asked Questions

TomTom is a capable truck GPS for North America with good routing accuracy. However, Garmin and Rand McNally have deeper US truck routing databases, particularly for bridge clearances and state-specific restrictions. TomTom excels in Europe and on traffic-dense urban routes.
Both receive traffic data via built-in connectivity (Garmin uses smartphone tethering, TomTom has built-in SIM). Core navigation works offline using stored maps. However, real-time traffic, weather, and fuel pricing require a data connection.
A quality truck GPS typically lasts 4-6 years before the hardware becomes too slow for current map software. Both Garmin and TomTom provide map updates for the life of the device, but performance degrades as maps grow more complex.
