TRIM RING INSTALLATION:
This page only covers special installation considerations for the trim ring installation. If the video monitor is to be installed in a vehicle with the trim ring, it may need to be trimmed to fit the contour of the vehicle headliner.
1)In this installation, the video monitor is mounted directly to the overhead
2)It is best to mount the video monitor to the roof structure without the trim ring first. There should be a gap between the headliner and the outer flange of the video monitor. The trim ring should be cut to fill this gap. Apply masking tape to the outer surface of the trim ring in the areas where the cut will be made.
3)Mark the cut to follow the necessary contour of the roof. The suggested method of marking is as follows:
A)First mark the narrowest point of the trim ring on the masking tape. Be careful to consider not only vertical location, but
B)Using the handle of a screwdriver, make a “transfer marking tool”. See diagram below. Place the tool against the roof and the marker against the masking tape on the trim ring. Trace the cut to be made around the entire perimeter of the trim ring.
C)Cut the trim ring using a sharp utility knife or shears. Make the cut in several passes over the marked line, each time cutting a little deeper. It is not necessary to cut completely through the plastic, the cut only need be over 50% of the wall thickness of the plastic. By bending the cut back and forth several times, the plastic will break cleanly at the cut.
D)Check the fit of the trimmed console and make any minor adjustments necessary.
4)The trim ring can be painted or covered with a material that matches the headliner before assembling the trim ring to video monitor.
5)The finished trim ring should be attached to the video monitor, then attach the assembly to the roof.
