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.

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.

it was the relay i replaced it and worked fine i pulled it now cause getting a new car and putting in that
