Obviously, if you are still under warranty and didn't hack the nav, you want the dealer to look at this. Alternatively, getting the '08 DVD update might help, because you don't have to hit "I Agree".
Thank you. I will stop by the dealer as we are still under warranty.
Stopped by the delaer. The lower half of the screen has a defect so they have to install a new nav unit - Thank god it is under warranty.
