It really doesn't matter. In speaking directly with Marvin Jefferies at Garmin I was surprised to learn that there is no difference in navigational capability between the least expensive to the most expensive Garmin GPS for vehicles. The difference in the price of the various units has only to do with extra features built in, not navigation.
Sorry, there was a problem. Please try again later.If I drove for a living, I would buy the best unit possible, especially if it was tailored specifically for the trucking industry. This unit can be set to truck mode; I'm not sure how accurate that mode would be.
