This mounting bracket has all the qualities you're looking for: lightweight, portable, adjustable. Bracket is jointed, allowing you to position your GPS out of the sun's glare. Comes with temporary and permanent adhesive disks that adhere the mount base to the dash.

There were two adhesives sent, one permenant one removable. The removavle did not hold the GPS mount. The mount itself is great. I bought double sided tape that worked very well, without leaving gooey tape behind.
