Google Map online illustration showing the meaning of icons

Can you post a screencap showing the icons you're unclear on?

 

Hi,
The following link takes you to Google Maps help pages for My Location and Compass Mode which you may find useful.
View the map - Google Maps for Mobile Help

You can access the help pages directly from Google Maps via the menu button.

 

I only see two icons that aren't in your notification bar. The red and white one tells you which way north is (red always points to it), and the small gray one, IIRC, will late your location (or approximation if your GPS is turned off). Do if you're just song around the map and feel the need to quickly return to "where you are", just tap that small, gray one.
