I bought an Arkon custom mount. I didn't want something on top of the dash, and this has a metal bracket - you pull off the bezel of the dash and mount the bracket using existing bolts. The bracket has a universal ball on it, so you can put on almost any type of mount. The one they sell for the GS2 has a spring-loaded bottom that you push down. It seemed too stiff at first, but loosened up over a couple of weeks. One thing I changed - it did vibrate a lot, so I took the bracket off and used some rubber gaskets on each side, and that helped. On my truck, it mounts just to the right of the Driver's right side air vent, perfect location and height for me, and you can tilt and turn it as you like.
