I recently purchased a 2005 S55 AMG it did not have the puck or the mount for the puck installed. I took the center console apart and found the factory wiring (coax and 10 pin AMP connector). I tried installing the mount and puck from an 07 and it does not appear to be getting power to the puck. Does anyone know if the wiring changed...or is it simply a defective mount?

Thanks
