2011 550i M-Sport
Hi. 1st time poster. I've got a 2011 550i Msport with the 10 pin controller. My issue is that the screen just starts flashing through menus and you can't control it. The controller seems to operate properly. Sometimes you can get to the screen you want and it will work, but mostly is flashes to the phone book screen. Also the backup cam will now work when it's doing this. The controller with 10 pins is over $400 so before i replace it, could it be the control module in the trunk? Anybody ever see anything like this?
