Installation Guide

VEHICLE PREPARATION:

1)Locate an accessory power source (+12v when key is in the ACC. and run positions, and 0v when key is off). Also find a location that will provide a good grounding point. Generally, this wire can be found at the ignition switch or fuse-box.

2)The mounting method and location will vary from vehicle to vehicle, so this manual will only focus on the installation of the video monitor and related accessories.

3)Generally, the best location for the video monitor is where the vehicle's factory dome light is installed. The monitor should be located in such a manner that it can be comfortably viewed by rear seat passengers. NEVER INSTALL THE MONITOR IN A PLACE WITHIN THE DRIVER'S VIEW. THIS IS NOT ONLY DANGEROUS, BUT IT IS ALSO ILLEGAL.

4)Once the mounting location of the monitor has been determined, there may be additional preparation work necessary, depending on the vehicle structure and installation method. Some of the steps that may be required are:

A)Removal of the vehicle's dome light

B)The headliner may need to be trimmed

VIDEO MONITOR INSTALLATION:

In this installation, the video monitor is mounted directly to the overhead cross-member in the roof using the mounting screw bosses. These screw bosses should contact the cross-member directly (i.e.: no gap between the screw boss and the roof structure). Also, be sure that the screws do not pierce the outer roof skin when fully fastened to the cross-member. It is important that the screws used in this installation are not overtightened, and that the video monitor is mounted in such a way that the assembly does not distort (or bend) when the mounting screws are tight- ened. An alternate method is to use a piece of plywood. First secure the plywood block to the cross-member, then screw the monitor into the plywood. See the drawing on page 5.
