I had the factory single cd and cassette player in my 2004 yukon denali with bose in my truck and went to switch wit a friend with a 2005 chevy suburban with bose that had the navigation setup. i pluged it into mine and it says "THEFTLOCK ACTIVATED" i unplugged it for a minute then plugged it back in before i left his house so ididnt have an open space there,and it turned on and worked but the volume wouldnt turn up loud..THEN i cranked the truck over to start and it said "THEFTLOCK ACTIVATED" again and now stays on..is there any way to clear this theft lock without taking it to the dealership?
