I installed a 2010 head unit in my 2007 and coded it with NCS Expert to my hifi amplifier. Everything works great, but I can hear feedback through the speakers at all times. I can hear the stereo spin up a cd or even the car's water pump change speeds. It is almost as if the LCI head unit is not grounding properly.. Has anyone else experienced this?

(Sorry to thread jack)

BMW GT1 (INPA, DIS, WinKFP, ect..), ISTA/P & /D is up and running! PM me if you want to stop by and code your car.
