Ok, so pretty sure we are all aware of the service code "1791" that can be entered on Nvai screen to allow DVD playback while driving.
Soooo.... the question comes to mind...
IF code 1791 allows dvd playback while driving, what does 1790 or 1792 do?
Or any other series of numbers entered?
Searched and didnt find anything but there HAS to to be many codes that do many things, no?
