I have a 2008 Chevy Silverado Pickup with Navigation package. My problem is the display goes completely dark at times. The radio still works and I can change XM channels from the steering column controls, so I assume the Nav is still working just the display is completely dark. It's very intermittent, sometimes it stays on for a while then goes off. When I start the truck it may be on or not. While driving it may goes off and eventually comes back on. Looks like a loose connection but I don't know where to start?


Anyone ever had a similar problem???


Thanks,

Robby
