Conclusion: Garmin's truck-targeted GPS is a solid first effort; but it could use a few minor tweaks.
Pros: Lifetime traffic updates included. Truck-specific routing for road restrictions. Extensive truck-centric POI database. Maps for U.S., Canada, and Puerto Rico. Multisegment routing. Lane assist. Truck and Car modes.
Cons: Expensive. No POI category for rest areas. Truck-specific data only for continental U.S.
