Update: I now have the pinouts for the AUX in on the NAV radio, But in order to make the headunit switch the audio to the AUX-IN a CAN bus message is required. This could be alot of work because I would have to create a circuit to communicate on the CAN bus and know the proper messages to send. It looks at this point like the CDDJ input is the only way for now, but I'm sure PIE, BlitzSafe or Visteon will have some solution in the future. In the mean time I will start looking at the CDDJ possibility.
