When on the AUDIO function, on the Touchscreen, next to the NAV button, there is 0' 00". It appears that this is a compass heading, but it does not change. Directly below that is a number. It changes occasionally, but I cannot tell what it is for. I cannot find any information on what this information is and how to use it. Any help would be appreciated.

 

Without the Nav option the screen will display the Compass, elevation and Latitude & Longitude. This is on the 2016 touchscreen.

 

Thanks for the reply. I do have Navigation function (Tom Tom), seems odd that it would display at all if you had Nav. Oh well.
