Hello all, first time using this site but it looks like there is a lot of help on here! I have a 2007 SG with a stock HK radio that no longer is working, I have seen a few older posts from a google search that match my issue and it seems to be that the AVC setting has gone bad... highest setting lowest setting or OFF does not fix it, worked on and off with radio restart for a while. On the other posts it said to snip the (white/green) wire, but I do not have that color wire and so far dealerships have been NO help!

 

http://www.ironcrossaudio.com/ These folks can assist.

 

That would have been my suggestion as well.

 

Thanks for the info, I'll give them a call

 

I agree!
