I have 2008 Overland with 132,000 miles. The navigation screen and radio will not turn on. The clock display which shows when the radio is off is also not working.
The navigation system won't turn on and the radio doesn't work. The clock that normally
displays on the screen when the radio is off isn't working either. The reverse camera is
out as well. It appears there is no power getting to the screen at all. It's a 2008 Grand
Cherokee Overland with 132,000 miles. The navigation system was changed three times
while under under warranty. Is there a fuse for the unit, the manual doesn't seem to show
one specifically designated for the navigation screen.
Have you checked the radio fuse?
