Hello, I somehow have a mediocre reception with the standard Volvo car radio. The sensitivity is much worse compared to other car radios in other cars. (Tested in comparison to the driving distance with the same set transmitter.) Can it be that the connection to the antenna in the glass window at the rear left becomes fragile and has no proper connection anymore? Or is the amplifier possibly the reason? I don’t really want to believe in a cable break, since the antenna nkabel is not constantly bent (except on the radio at the back directly). Is there possibly a radio setting for the sensitivity of the reception? Has anyone here already gained experience? Thank you!
