... Install a AV Electronics Input for their NAV to get DVD's, I bought one a while back and its sitting in my garage... I saw the write up, but wondered if anyone has done it.

Partly laziness why its not installed, part scared, and part, I have a engine noise thing from my stereo install that I wanted to take care of 1st... no clue, might try to get that ebay grounding kit see if it makes any difference.

 

I have not, but I would be very interested if it works

 

Since I have no Nav, I obviously haven't done the AV Electronics install. But I expect the engine noise issue will be solved with a ground loop isolator.
