I put mine on top of the dash all the way to the left. I used some of the hook side of self stick velcro and stuck a couple of one inch pieces to the bottom of the gauge. It grabs hold of the carpet DashMat I have on the dash. If you don't have one of those you'd have to also stick the loop side of the velcro to the dash. Doesn't block the windshield and easy to remove.
You can be anything you want on the Internet,
it amazes me that so many choose stupid....
