What a great mount! Unlike many other solutions that use universal cradles, this is manufactured specifically for your GPS. This includes a cradle that fits the back of your GPS just like the one you got in the box..
The popular Cup Holder Mount is about 5" tall. It features an adjustable flywheel base that expands to fit varying cup holder opening (up to 3.5 inches wide) except for those that are so large that the 7-Eleven Big Gulp falls over.
