I was hoping someone with knowledge of the factory 730 stereo could help me.
I want to install the Rosen DVD headrest players on my '12 Overland and want it to play through the stereo, but not using the FM band, is there anyway to wire that way?
If the Rosen system has an A/V output, you could use the AUX input on the front of the 730. Otherwise, a Lockpick? You could also connect the A/V output from the Rosen (if present) to a bluetooth transmitter, then select this as a source and stream your audio. There are a few good bluetooth transmitter/receivers available. I have one that runs from 5V, so it could get its power from a USB connector. I use it to send audio from my home jukebox to my audio system.
