Mio P550 + Memory Map + PocketFMS
I’d recommend the Mio P550.
I’m using it with the CAA 1:500,000 charts and with PocketFMS (for trips beyond CAA Land).
It comes with WiFi, BlueTooth and truly dire battery life! It needs to be fed from the aircraft (12v) supply.
I’m presently using a 2Gb card. This contains all three CAA charts, a selection of PocketFMS FIR’s and a good selection of music tracks. Although the latter are not strictly necessary for aviation….
Safe Flying,
Richard W.
