Having terrible interference problems with my radio on all stations. My car is a diesel tourer with satnav. I know the aerial is in the rear side window (don`t know if its both side windows or just one of them) and I remember CJ you mentioned elsewhere that removing the connecting wires to the aerial and then applying a thin smear of vaseline might help. Where exactly is the connection made and how do I get to it. I`m going to try this first as its a no cost fix if it (hopefully) works before I start worrying about a faulty radio.
