The nav radio freezes up. Restarts randomly over and over. Can still tune the radio and sound through steering wheel but cannot see anything on the nav screen. This happened a day after the car was purchased. The dealer was contacted and said that the warranty was up. Would really like to get this issue fixed, as this is why the car was purchased. For the navigation feature.
Satellite/fm/am digital radio does not function properly. Radio has been replaced and all connections checked. Satellite works fine, fm only works with strong signals around and the am does not work at all. Car dealer does not have any solution and only says that the problem should work it self out once the all digital signal are utilized. Dealer says an non-digital radio cannot be installed.
