I agree that it has a Garmin roots, I wish it had the Garmin interface. I have used the GPS for at latest 50 hours of driving time. One of the feature My garmin has is that it will search for an address in 3 states. I live in NJ but the Garmin will search NJ,PA and NY. the one in the Ram, I have to put in the state, city, it cant even detect what state I am in currently but will default to the last state entered. I tried the re-route option once, took me through the worst part of Philadelphia and side tracked me for over an hour, I have seen it tell me to turn and then at the last min, change its mind. the constant nagging about traffic ahead is so persistent that i have to turn the voice off. I maybe doing something wrong, but I have been using GPSs since they first came out, if anyone has any suggestions , I am open.
