Well FF I do agree with you. I normally fly an aircraft with fitted (obviously) twin G430s.
Last Friday, though, I had a great day out flying all round the Cotswolds, S. Wales, Lundy, the West Country and back in a VFR-only aircraft.
I took the G196 along and was hugely impressed with how flexible, reliable and accurate it was for all aspects of a full day's flying and navigation. We used the G196 as our sole planning aid as well as for nav in the air.
I didn't have it on a mounting, but I could have used the yoke-mount, or you can get a panel mounting thing for it.
I haven't got a connection with Garmin or anything like that; I'm just posting because I was staggered by how good it was on that day.
