Migsel RAM mount on a GSA?

[RAM-man]

That's a very good point as the Garmin in fact goes vertically whereas the Tomtom goes horizontally. I will check with the dealer maybe the mount can be rotated. Holes should be the same, AMPS standard

AMPS fix pattern is approx 30mm x 40mm (its nearer to 38 if being picky) so depends where the holes have been made governs how you can attach the cradle. RAM-B-347 is square base with four corner holes (AMPS) where as RAM-B-202 has matrix of holes on same pcd and makes two hole patterns, one of 'em being AMPS.. number of twats who fail to align up some holes beggars fecking belief, so use square base RAM-B-347 as its idiot proof.

Garmin Zumo and TomTom Rider 2 (Urban as well) fit AMPS.

TomTom Rider 1 has a four hole pattern but its *not* AMPS.

TT cradles usually align to RAM-B-238 diamond base on the underside of cradle , remove crossbar clamps and use two centreline holes.
