Yes, the Garmin 705 is a big part of the problem , I have to slide it horizontally onto the mount which means I can't have anything else on the bar where it slides on/off. I guess I will have to go with a Garmin upfront mount and quarter turn adapter. My bike has narrow handlebars and I have bar tape which may need to be unwound to allow a little more mountable bar area.
Thanks for all the posted idea's to explore.
