I just replaced the stock radio in my '99 SL1 with a new Kenwood AM/FM/CD. Made sure I had the correct wiring harness adapter, antenna adapter and mounting kit. CD works like a charm however I'm having major reception issues. Removed unit to insure the antenna cables were connected. The weird part is that, if I run my hand around the outside of the stereo, certain channels will come in clearer or get louder. Other station that are local and come in strong in my other car don't come in at all. I noticed that the antenna (stock) had a wire 'wrapped' around it. Is there a fuse I should be looking for?
