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)
I have a workstation set up with DIS, TIS, SSS, INPA, NCS Expert, WinKFP, Tool32 with an K+D CAN interface; PM me if you want to stop by and code your car. ISTA/D + /P with an iCOMM interface finally here!
