The Ford Explorer has multiple terrain settings. However, a very common feature, especially in German vehicles is an altimeter. I live in Colorado and it is especially useful for me. This seems like a very simple add to the navigation system. Please add.

On another car I own you just touch the icon where you're at on the GPS screen and it tells you the altitude.
