Improve radio reception

[MrLapou]

MY 2009 Sportback is fitted with OpenSky and Concert2+ incl Bose.
Trouble is the radio reception is so bad, it's like a 1970's car.
I think the antenna is part of the heated rear window.

Any suggestions on how to improve on this?

Get a new rear window !

Common fault - you can test by switching rear screen heater on and off. Get's worse when heater is on.
