I looked at the Pilot III, but its a bit small and fiddly to use when you've got both hands full in an R22. Especially if its mounted on the cowling about 2 feet away.
Have a look at the Lowrance Airmap 100 - thats the one I was going to buy (before the motorbike broke a conrod - ******).
Slightly bigger screen, and comes with all the gadgets - including a cradle to mount on the yoke/t-bar/whatever; a cigarette lighter adapter and cable; PC synch cables; external aerial; batteries, you name it. Plus all the screens were customisable for layout and content. What more could you want?

As with any GPS you choose - TRY BEFORE YOU BUY.
