2.Test fit the overhead monitor system on the ceiling of the vehicle, verifying it is not going to interfere with the safe operation of the vehicle and is physically safe for the driver and passenger(s).

3.Once the mounting location of the overhead monitor system has been determined, carefully mark the location with masking tape.

4.Lower the vehicle's headliner down to see if a roof support beam is available to screw the mounting bracket to. If a support beam is not available to screw into, use a ¾" piece of plywood cut to the appropriate size. Attach the plywood to the roof of the vehicle using silicone allowing adequate drying time before proceeding.

5.Screw the mounting bracket in the vehicle. DOUBLE CHECK THE LENGTH OF THE SCREWS PRIOR

TO MOUNTING THE BRACKET, TO PRECLUDE PENETRATION OF THE VEHICLE’S ROOF.
