Hi, I have a 2011 X2 F25 and am having a few issues I would like to try and fix. My issue (like others it seems) is bad reception on my radio, I used to have a signal strength indicator on the head but that seems to have gone.

I have changed the diversity antenna, and that helped with my fob reception but not the radio. checking the voltage I noticed that I have no power coming out of the 2 pin connector coming out of the antenna going to the window. I also only have 6 volts coming out of the while wire (going into the antenna).

Would any one have the wiring diagram or know what the voltage is going to the white wire going to the antenna?

Thanks for any help

Mike
