about 2 years ago I bought a garmin reconditioned unit for about $145. I got it through Circuit city on line. Early on the Garmin units had truck routes, then the lower end models left that feature out. Then only special units came with the option. Try looking for a reconditioned older unit, You might find it cheap, I have a nuvi 350, it has truck routes, and most of the streetpilot series i believe has it too.
