This is the way I use Pocket FMS in the plane

IPAQ mounted on steering yoke with help of a Garmin mount.

The TomTom GPS mouse is mounted above the IPAQ

If you look on the PFMS screen, you can see Croatia when I am enroute from Gratz to Split

I made a special power supply from 28 V board voltage converting to 5 V to feed the IPAQ and GPS mouse
