How do I adust the windsheild mount?

I just got on myself. It is deceiving but it can adjust. You have to be very firm with it. I strongly recommend NOT having the GPS unit attached or having the mount on the window when adjusting as you have to bend it hard to move it. Just bend it whatever direction you want it to move and it will move. It is just VERY stiff. My guess is because that helps it maintain whatever position to bend it into. Good luck.
