I installed a Pro-Clip system. Make sure you look up both parts - one is the part that mounts to the vehicle in our case the vent mount and the other is the part that holds your gps. Very happy with this set up. The vent mount clips into the to inside passenger side dash vent and to the center dash panel. Has not moved since I installed it about 3 years ago. The gps mount I have is has swivel, lock and pass-through power. I hardwired the power and ran all through the dash. I'll try to get some pics soon.
