Just spent too much of the last 2 working days surfin'
trying to research this. The difficulty of getting information is representive of the fact that the solutions are still in their infancy. I downloaded 4 demos, and came away feeling less than enthusiastic. for what it's worth:
PocketFMS (freeware) - I think this will eventually do the job (actually prefered the map view to WinPilot), but it is still clearly a Beta. Didn't like the interface as it stands.
NavGPS ($199 for Pro version, $99 for Basic) - Only looked at Basic which doesn't come with a coloured Terrain Map. Didn't have my home airfield - scratch.
Memory Map (c£150 for MemoryMap Navigator and 1 CAA Map) - I could see this working well in the cockpit, but without an HSI, you're missing some of the real benefits of GPS.
WinPilot ($299) - Good looking solution, however, the User Interface is very clunky. Not sure about using this in a cockpit.
No demo available for AnywhereMap, but it certainly looks the business. Still at $500+ its dear - might as well get a Garmin Pilot 3.
Current view is that I will get the bluetooth GPS (seems a waste not to as I have got a bluetooth PDA), and play with PocketFMS, until the payware solutions get friendlier/more cost effective.
Any other thoughts?
