brianteel Posted January 11, 2009 Report Share Posted January 11, 2009 is it possible this relay went bad that fast. i am not getting the ign switched power out of the relay causing the radio not to come on. any help would be great. I installed it last night with the f90Bt in a 05 silverado with bose and onstar. Quote Link to post Share on other sites
GQRilla Posted February 15, 2009 Report Share Posted February 15, 2009 Hope it's not too late to help here. The os2 is a somewhat problematic piece. Chances are the relay isn't bad - either the os2 is bad or you need to install a diode across the 85 and 86 contacts of the relay (check pac-audio.com for the bulletin on the fix). I have seen several os2's go bad in my life. Quote Link to post Share on other sites
