Here is a youtube video of one of the screens you can get to; digital speedometer FTW!

The same guy also has a video of unlocking the buttons that you can't touch while the car is moving.

And here is how to do it:
"Here's something to play with if you have the Navigation option. Go to the menu, Navigation Setup. Click on Calibration, then Show Version. Now, with the joystick do two clicks up, then two clicks down. You now have a new menu with choices of screens that get into details of the satellites, dead reckoning sensors, GPS based digital speedometer and other fun stuff. I am not sure it is good for anything except entertainment, but is it always cool to have cheat codes for stuff. You can check you speedometer accuracy.
Have fun and let me know if you discover anything else."
