Installation

The GPS antenna is pre-wired and has a 1 meter foot
cable running through one of the HeycoÆ
connectors.
Determine location for GPS antenna. It is recom-
mended you place the GPS antenna 1 meter from
dome.
The recommended location for the GPS antenna is
based on having a level location and a clear view of
the sky for the best satellite signal acquisition.
IMPORTANT! The GPS must be located 1meter
away from obstructions on roof of vehicle and other
obstructions such as trees, tall buildings, etc. You must
have a clear view of the sky for proper operation.

CABLE-
ENTRY CABLE
1. Decide the best location for the cables to enter
the vehicle, and the location of the switch and re-
ceiver (see ìInstalling the switch and receiverîon
page 10). Drill a 1/2î hole in the roof, push wires in-
side. Make proper connections.
You must have filtered +12 VDC power source.
2. Place cable-entry plate over hole and cables. Screw
in place. Seal plate and screw holes with approved
sealant (not included).
3. Depending on the length of the cable on the roof,
you may need to use cable clamps or wire ties (not
provided) between the unit and your cable-entry plate.
Clamping the cable every 12î-16î should eliminate
any unnecessary
cable movement,

switch should be close to the +12 VDC power cable
coming from the MV-0099. Be sure the switch is
turned off before you begin! See diagram on next
page.
Wall or panel mount: Drill 1-1/4î hole, pull wires
through wall or panel.
Surface mount: Determine location and direction of
box. Mount box feed wire into one of the box open-
ings.
Select plate cover (brown or white provided) and snap
the rocker switch into the switch plate. Be sure switch
is off!
