This is not a post to describe why, unless I need too, just a few pictures to show what it looks like to have both a Zumo 665 (left) and a Zumo 660 mounted and ready to go.I used the iron aces mounts, although not as they were intended, but I am happy with how it looks.
Thanks for sharing...I am looking to do a similar mounting with my gps to free up some handlebar space as my gps is currently on the left and my phone on the right handlebar...will look into those mounts...
