Any one have the procedure to unlock a tnr # 10377287 installed today in a 07 classis non lux bose. seems like it will be ok when I first powered it up, it said( CHEVY sound by bose) after cycling the engine it now reads (GMC sound by bose) I,ll take that as a good sign although the theft lock is now on. most of the dealers here say they cant do it, may be if I can bring the instructions we can get it unlocked & also adjust the load chime
Thanks
