Don't know why anyone would need this, and your current coordinates are also available under the "Emergency Info" option while in Nav mode; but I just discovered this:

1.) While in Nav mode, hit Settings-->Map Display Options.

2.) Touch upper left corner of screen, then touch upper middle portion of screen, then touch and hold upper right corner of screen. You'll now see a message pop up: "Lon Lat disp flag: off".

This sequence of touches toggles the constant display of longtitude/latitude coordinates on the map display. If you've turned them on by using these commands, just repeat the steps to turn off the constant lon/lat display. Note that the sequence of touches in step 2 are the same as those to enable password protection; these are just on a different screen. Enjoy!

cool! its just something new.

Very cool, is there a sequence like this that can enable the display of Elevation?

How the hell'd you figure that out? Trial and error?

Pretty much. I went through the password set up steps on the other screen; while doing that I figured that the Pioneer software people wouldn't have put that much time and effort into programming that touch sequence for just one screen/option - so I tried it on every other screen. The lon/lat toggle is the only other Easter egg I found using that sequence, though.
