There could be multiple reasons why this issue has occurred. Please keep me posted.

wow, great advice, keep it coming.

OK; let's start easy

1. fuses?
2. pull battery, wait 10 min, re-connect battery
3. push 'hard' button (side buttons)
4. do you always get audio?
5. signal chimes?
6. under warranty?

 

Hi,
Thanks but I tried filling the fuses and hitting the hard buttons. Audio is fine, chimes signals all that. In fact when you get in the truck first thing in the morning it will come on long enough to tell you it can't read the map DVD then starts its "flake out" and you lose the screen (backs out) cuts in and out like its resetting.

Under warranty - no
Trust local dealer - hell no..

 

did you remove the battery for 10 min?

did/can you remove the NAV dvd?

is there anything in the CD slot?

 

i have a video in motion unlocked nav in my 08 suburban. i was wondering if there was a way to use stock nav to play video on my aftermarket pulldown monitor on second row and be able to view it simultaneously front and back while driving.
