Find the best location on the dash
Before removing the protective sheet from the base, open the lens and try looking through it. Make sure it doesn't block your view — normally, it should be at the bottom of your line of sight.
Install it on your dashboard
1. Peel off the protective layer, and stick the base to the dashboard. The arrow should face the windshield.
Notice! Wipe the dash to clean and degrease it before applying the adhesive mounts.
2. Connect the device to your car OBD-II port.
3. Place the device onto the base and move it on the the sliding disc to find the needed device angle. You can further fix the disc position with a hex key enclosed.
4. Open up the lens and adjust it to the appropriate angle.
