Thanks to advice from this forum.
I mounted my Garmin 2610 GPS using suggestions from this forum. The unit is centered [love that] and does not block the instrument panel. It can be repositioned higher if my tank bag is used in the extended position.
[last 3 pics].
Using RAM GRAD / GRAB11 / GRANA and Tucker Rocky slip lock bolt assembly for the handle bar ID [remove rubber plug]. I replaced the supplied 8mm bolt with a stainless hex head bolt and washer.
I bought the RAM cradle as well as the Garmin cradle for the 2610 unit, but I prefer the Garmin design. It is smaller and has a recess that captures the plug termination [3rd pic, right side of cradle].
Very slick. Thanks again.
