Does it show more mpg information (ie: consumption, energy flow, like the gen 2) in addition to the back-up camera and navagation capability?
That information is available, though, through the top screen left of the speedometer in the 2010. You don't have to have the NAV option to be able to see all of that information, and those that do have NAV also have the upper screen. I just wanted to make be clear that this information did not disappear in the 2010 models.
The hidden (*) Service Screen lists the active GPS satellites' positions and signal strengths. However, I do not think it showed GPS-calculated speed ... but I was not moving when I looked at the screen. (*) On the left, touch 3/4 up, 1/4 up, 3/4 up, then 1/4 up after pressing the INFO and then the DISP buttons.
