07 Yukon Denali GPS Troubles

[Colton92]

I have a 2007 GMC Yukon Denali XL with Navigation. I recently pressed the eject button on the gps and it froze up. i ended up turning the car off, once i turned it back on it said there was no gps disk in the slot. but there is a disk in there. I was wondering if anyone knows how i could fix this?

Take out the disc, unplug the vehicle's negative battery cable, and try to start it to make sure to drain any reserve power. Then, with all doors closed, rehook the cable and start the engine, then reload the disc.
