Ask for help from experts. I bought the factory Cadillac CTS-V DVD head unit and installed it on my 3.2 with automatic transmission. Immediately there was a problem, the device does not play a DVD, and does not allow to use settings. What I did not do the device thinks that the car rides, including if the motor not started .. Who knows what the problem is? Is the root of the problem is that the CTS-V has a manual transmission, and my Cadillac-automatic?
