E70 radio reception

[russ25]

poor fm radio reception keeps researching for station and has a lot of interference , just had new rear window fitted and still poor.
noticed its ok with just ignition on soon as you start engine fault starts.

Could be the antenna diversity module in the back of the car, or connections to both the rear and near side rear windows.

didnt know the side windows were involved to.

You should be able to see elements on just the near side rear quarter.
