Case for eTrex Vista

Every hand-held GPS user knows that the unit is...pretty much held by hand.
Where to place it, is then the next issue. I have read of people placing it on a hat, making a special glove or wrist holder, building complex arrays for a handlebar, or simply using a belt clip case.
I have the Vista HCx with navigation features and this requires systems/mounts to place it on a bicycle and motorcycle handlebar, and a car dashboard.
After using the original Garmin belt clip case and the handlebar support, I've had enough of bad readings through the transparent plastic and the handlebar support is too weak. Car dashboard mounts can be bulky, complex or mislocated. Magnet-style supports aren't strong enough.
Enough to develop a self-made different concept! That is, a simple case/holder featuring velcro strap to be attached anywhere there is velcro counterpart. The sticking velcro comes with strong glue that hardly comes off, anyway a few stitches, where applicable, prevent possible failure.

The following images should explain, click on them to enlarge. Here you can see an ugly prototype that solves all problems. Currently making a nicer looking one. I've been thoroughly testing the system and found it very reliable for all applications, including MTB riding through severe vibration and shaking conditions. Just always remember to tether the GPS with a safety lanyard.
The concept is applicable to most GPS and navigator brands and models.
Your comments will be much appreciated. Enjoy!
