Does somebody have the same problem that the bose system gives music from the right speakers and sometimes from te left speakers?
I had the same issue with my car just when I got it (no BOSE unfortunately)
Found that the issue was that the GPS was programmed to a destination, so it should give voice directions once in a while.
Because the volume for the GPS voice was set to "0" nothing is heard, but anyway the normal sound is reduced for the duration of the voice message. Not sure if the explanation made sense?
