I really like GPS devices and have owned several of them over the years. GPS is much better than having to stop and ask directions or having to listen to the wife tell me I need to stop and ask directions. I always figured that the big rigs on the road had built-in GPS, and I am sure many do.
Garmin has announced a new GPS device for long haul truckers that may make some want to upgrade even if their rig has GPS built-in. The new nuvi 465T is a GPS device that allows truckers to put in the length, width, height, and weight of their truck along with cargo type and the GPS device will find routes that the truck can safely and legally take.
