I recently bought RAM's "Suction Cup Car Suv Windshield Mount Holder for Gps Garmin eTrex 10 20 & 30" and while it is solidly designed, it doesn't allow use of the power cable in the mount when used in its "right side up" manner. The power cable comes out the back at the top, and the one that Garmin sells is 90 degrees straight up into the air.
The roller clip at the top is exactly in the way, and an attempt to use it damaged the connector on the cord in less than two days.
I realized that if I used the clip "up side down", with the roller clip at the bottom, and cut out the plastic notch in the top (now) of the holder, the cable would be free of binding.
After doing that, I found the buttons on the left and right of the device were largely obscured by the sides of the holder. So I cut out rectangular openings on both sides so the buttons are easily accessible.
RAM should adopt this design. See photo.
