If you choose to fill in the cable hole, be sure to position the cable against the rear edge of the hole as you apply the fill material.
Before positioning the gimbal bracket, be sure to hold the cable against the rear edge of the hole. Then, slide the bracket over the hole and butt the rear of the bracket base firmly against the cable, thus pinning it in place against the side of the hole. Finally, fasten the bracket to the dash.
Front 
Install the gimbal bracket. Orient the bracket so the arms slope to-
ward the front of your unit.
Attach the unit to the gimbal bracket using the supplied gimbal knobs and washers. Slide the rubber washers onto the gimbal knobs then loosely screw the knobs into their sockets. Slide the unit into the bracket with the rubber washers to the outside of the bracket arms. Tilt the unit to the desired viewing angle and tighten the knobs finger tight.
