So I conducted a search and can only find threads about xm not working. My radio modes only go through fm1, fm2, am. It dies not go to cd and xm. I found that a plug in back can be the problem for xm, but could not find out anything. Hands free link still works. My head unit may be going bad. Also i pulled the stock amp prior to ths happening, but i dont think that has anything to do with this. I may have not been searching correctly, but I know I can rely on the a-zine community to help out. TIA
