Ok... Here is the question. I need confirmation to my thinking. After downloading the installation instructions for the Infocrap system it appears that the only tie into the ECU is the jumper harness that piggybacks into the normal diagnostic port used on the standard SS. Other than the three wire power connection and the reverse switch for the backup camera there shouldn't be any other connections into the SS system correct?
Trying to isolate it from any feedback to the ECU and was hoping I could still have music until I replace the unit with a better stereo ... Just trying to remove any possible cause to the 065620 code I get.
