Guys... I have noticed a bit of a strange one on my FF.. When you put the heated rear screen on while the radio is on you get some serious interference the moment the button is pushed until you turn the heated screen off!! It almost seems like there should be some kind of line suppressor fitted to the screen elements. I understand that the heater elements are also the radio ariel as well.. any suggestions?

I had this on my L322. The dog had scratched at the glass and damaged the heating elements. I had to have a new rear screen ( but I persuaded my insurers it was damage to glass and therefore claimable under the glass element of my policy!)

Mmm thought that might be the case, checked all the antenna module wires and connections and all looked good, clean, and dry, I noticed one line in the rear screen was not defrosting, is this enough to do it?... 2006 RR sport HSE

I have exactly the same problem, one bit not defrosting and I think it can cause the interference, I have to use DAB then switch to Radio after switching off the screen. I was going to try some electrical paint - when I get round to it  Geoff

I was thinking about the electrical paint option, but the car is still under warranty from the garage I bought it from! Think I might chance my arm and see if they will replace the glass under warranty 2006 RR sport HSE
