I agree 100% with F5 and the others about getting a handheld. In a couple years, any in-dash Nav unit be obsolete, unsupported, the novelty will be long gone. And every time you get in the truck, you'll remember that you paid almost $2k for that thing. A handheld or portable GPS goes with you on trips, and if you stick with industry leaders like Garmin and Magellen, they're very well supported and data upgrades are reasonable, and they don't rely on third-party software.
