Im running an identical setup... I have the MOST AUX wired to constant 12V. When I crank the car the unit goes dead and won't produce any audio or even allow the radio to work until I unplug the most bus and plug it back in. It seems like I need to reset the most bus each time. When I crank it seems like the MOST BUS goes open and nothing syncs. I have the remote wire on a switch like you per the instructions but it seems like the MOST-AUX is the issue since all that wire does is enable the AUX to produce audio. Thoughts?


EDIT:

I think I found my answer. My battery goes to 9.3VDC when cranking causing the issue with the MOST-AUX. Basically it is dropping the loop out. I will update this once I get her charged/and or replaced in case anyone runs into a similar issue.

 

Hi Did you ever get this to work correctly. I have similar issues with the Nav-TV MOST AUX
I really just want to get a decent audio input on the factory system.
