05 Yukon Denali Navagation radio won't turn on after battery swap

[AaronIROCZ]

Swapped the battery in my 05 Yukon Denali and now the navigation radio won't turn on. I push the power button and see the backlighting turn on but nothing else. When I hit the power button again to turn it off the clock is displayed. Any ideas???

Unplug + and - connection see what happens.

Ok got it figured out, the isimple ipod adaptor got screwed up some how and wouldn't power up properly thus the radio acting like it did. I unhooked it and left it unpowered for awhile and rehooked it up and now all is functioning again.
