I use a Garmin III ( Nav) and iPaq (half or quarter mil map) which are great.
Problem is trying to find proper mounting. I'm currently using a "homebuild hybrid" which is the base of the Garmin yoke mount and a car phone/gps mount bolted together. It's rather Heath-Robinson as it's a bit top-heavy and sort of sways around in turbulence....
Any mounting suggestions ( for the sat-nav!) gratefully received.
