Ive found this to be v useful, have the CAA south of england chart which cost another 18quid, running in the background on a standard windscreen mount for a car, for doublechecking airspace and such, and as a back up when, as IO says, you're on an unplanned bimble.
does anyone know how to make it show your track onscreen while flying? i have it set to show predicted track, but cant make it show where ive been.
