Mav said:Yes, RF is bad for my BMW too. On my other car, my FM transmitter sends clear sound. On my BMW, there is some whining background sound that is proportional to my acceleration (dun ask me why).
I tested with turning off the HU radio and the sound goes away immediately.... Sigh! Now I am exploring other mods to link up to my HU directly.
