I bought a Garmin 660RV - cheaper that the 770RV and has built in traffic. I believe the 770 has to use your phone thru Bluetooth for traffic info. I want my phone bluetoothed to the truck. I also bought some bridge height points of interest from a company called LowClearances.com but the installation instructions sucked and I have not been able to load them into the garmin...basically wasted that $40.

The garmin did warn us and reroute us in Memphis last summer.
