I have a 2009 Tahoe with the most updated navigation system DVD. Sometimes the display goes blank. To date it eventually just come back at some point. Usually within an hour or so the same day. Any ideas on how to fix this issue? Thanks.

I'm sorry you are experiencing this issue. This may be due to a signal wire circuit short. This is just a suggestion and is not meant as a diagnosis. I recommend consulting with a certified technician for an official diagnosis. They will be able to offer more information after inspecting the vehicle.

Please keep us posted.

If you need assistance locating a technician, please PM me your zip code for a listing.
