Long headless bolt - notched plastic ball (TomTom size; larger for Garmins).
Are you satisfied with this solution?
I installed this RAM mount for my Garmin Zumo.
I use my Garmin in my Morgan and on my Kawasaki motorbike and in various rental cars.
Only on my Morgan I notice
poor GPS precision whenever I am between mountains or high buildings.
On flat terrain it works fine - as ususal.
I suspect that the
metal dashboard blocks half of the sky so that the Garmin can't calculate a good position fix.
An external antenna might help, but I haven't tried it yet.
