Location screen in NAV.

So far it looks like features on the 2010 nav are similar to those on my 2005. This works for me:

On the primary map screen the second button up from the bottom from the bottom lower left corner has a graphic in it that indicates the default screen. Press that button to expand that row of buttons to show available screens. Select the last button in the row to view your coordinates. I have not found a way to display elevation.
