2006 magnum nav system display

[hritcey]

The stereo/nav system display on my 2006 magnum works at start up and then goes blank shortly after as the car warms up. It has very intermittently come back on after but usually stays blank. After prolonged driving all the system controls (except for volume) also stop working but resume functioning after the car is restarted. Haven't had it checked out at the dealer yet but thought I'd see if anyone else has had similar symptoms.

from a FOUR MAGNUM family in North Carolina. I have factory Navigation in my 06 SRT Magnum and so far (knock on wood), no problems with mine. I know you have to be extremely careful with the joy stick; heard a ton of those have broken off.
