How the hell do I call the helicopter in Tutorial ?

It says open map "M" I do that.. then says to double click on the Radio....

I only have Compass/Notepad/Watch and what I assume is GPS... no radio there.. double clicking GPS does nothing.

How do I use the radio?

I think you are talking about the "03:leader course" mission. You should see the radio and the text on its screen, just clic on the text.
