Sorry to take so long to respond as I thought I had the solution with a toyota T-SB that was supposed to fix this issue. The guys at my dealership got the part sent in from the US to fit it, did fit it for me, but no change to the interference. so they took it out again and said they don't know what to do next. Its been 2 months and I haven't heard anything from them about a solution. They say, just don't plug it into the charger! Anyway, the noise is only there when using the ipod when it is connected to the power source, ie cigarette lighter. No noise with radio, or CD or ipod without charger. thank you for offering solutions. I will take your suggestions to the dealership service centre and see what happens. Many thanks, Kay
