Pete, I'm really interested in this unit, I gave memory map a ring because there wasn't that much info on the Flightstore website for flight planning etc etc. They are going to be at a Flying show on the 28th Nov at the NEC in Birmingham so I'll probably pop up there and try before I buy.
I've tried Memory Map before and it was ok but it won't come with all the bells and whistles and the handy "direct to" when your in flight. Still think its a good unit and half the price of the Airbox and Flymap units.
