Installed a P10 HD tuner with my Z2...when soure is pushed to get to HD... Screen comes up with all the controls. but it reads tuner er, and I can't use any controls..it seems everything on hd is frozen.....any thoughts on this??

Thanks...there is a volume adjustment in back of head unit..if it's in between clicks, volume goes soft and loud....thanks again

one day chimes(seatbelt.reverse.etc) work. next day they are muffled...couple days go by. they are working again...What do you think?....I have a z2 in a 2007 avalanche......mike
