Clock on my premium navigation system
I just plugged in my I phone as I have numerous times before and the time on
my system disappeared.
I have the same problem - happened right around the time yours did - still trying to find answers
Take out the SD card from behind the SD Nav panel on the entertainment console and turn off car and then reinsert the card and restart car. Just be sure to do this is open area so the system will connect to the GPS satellite. The system will reboot and clock will return.
