I found some of this information while browsing the forums, but not all of it. If it has been mentioned before I do apologize.

Anyway, we all know about entering the diags mode by using the correct button combo, and if you go into the gps menu within the diags screen and hold the menu button, you get even more detail like current mph and heading.

Anyway, I found that if you hold the menu button on the main sceen, you get another menu. Here you can see what apps are loaded, error messages, and can can change the color of the displays. It even looks like it is loading the trip and ac files when you look at the software.

Anyway, thought this might help those that are trying to hack the navi, and again I did a search and didn't find anything abouth getting into this menu so just thought I'd mention it. Apologize if it is well known.

 

weird.

 

Very interesting. Just tried it out. Might have to try to change the map color, something more green. I will have to play with it and see what I like. Great find.
