I tried both, the original GARMIN yoke mount and the RAM device. I
prefer the RAM solution, very stable. The Garmin original is not so
adjustable and the screw-knob is at the bottom, so it conflicts with my
knees, eg when flaring to land. In general, mounting the 196 on the 172
yoke is possible, personally i prefer the big RAM suction cup for
mounting the gps unit just above and next to the glareshield.

Just my two cents
