I started m '05 Wrangler TJ the other day and discovered that the FM portion no longer worked. The CD player and AM work fine. The scan function on FM still locates channels, but no sound. I checked the the antenna connector and there was no corrosion or anything out of the ordinary. The radio unit is a refurbished OEM model and about two years old. Any ideas on how what happened to the FM channel and how to get it back?
