It is all good info for me. I will start with the head unit first and work my way back to see where this is getting the interference. I have done quite a bit of work to my car, so it is possible that it is something I screwed up. Add to that the harmon kardon and I have a problem that I may never get resolved. I also need to get a lot of the other items I have connected removed and returned to stock to see how it sounds after that. It is going to be a bit of a tasking to get this resolved....
