I made this video so those of you with NAV systems can do some DIY testing to get into the guts of your system.

To my knowledge, this test mode is a lot like the instrument cluster engineering mode, in that it's read-only; e.g. you can't break anything by messing around in there. I haven't managed to break anything, and I've tried everything I can think of.

Hope this helps.

P.S. I'll save you some time - I was at a car wash when I shot this video.
