I have noticed two things with the radio in my car
1. The volume seems to go up and down randomly all the time (not the actual volume level on the radio, that stays the same. But the sound gets louder and quieter)
2. I have also noticed that something in the radio keeps getting mobile phone interference, which is annoying. This even happens when the radio is turned off, and i can also hear a quiet 'static' sound in the background at all times as if the speakers are still on even though the radio is turned completely off.
I have the Bose speakers if that makes any difference?
