3.1 Determine system layout
1) Determine the location to connect to the vehicle speed signal. Please call 1-
86NAVMATE1(1-866-286-2831) for VSS help.
2) Determine the location to connect to the remaining vehicle signals required by
NavMate. Please refer to Table 2 on pag e5 for signal requirements and NavMate
wire colors.
3) Determine general component layout, e.g., where the controller will be mounted.
3.2 Connect wires and route cables
1) Connect wire harness to vehicle using splice(piggyback)method. Using a multimeter,
verify the battery, ignition, ground, and backup connections.
The NavMate system wire harness has five wires which must be connected to the
vehicle. See Table 2 on pag e5 for requirements.
Ground (Black): Connect to a vehicle ground. Maintain the shortest ground loop
possible by connecting directly to a body ground point if available.
Ignition (Pink): Connect to a circuit which is powered only when the key is in the on/
run position. An example is the turn signal circuit.
Battery (Red): Connect to a circuit which is powered constantly. An example is the
hazard signal circuit.
Reverse (Light Green): Connect to a circuit which is powered only when the vehicle
is in reverse. An example is the backup light.
Speed signal (Green/White OR Yellow): The vehicle must have a vehicle speed
signal (VSS) output in the form of a square wave or a sine wave. Use the green/white
or the yellow wire, depending on VSS type. (See Tabl e2 on pag e5.) Connect to a
circuit which carries the signal that drives the odometer.
Special attention must be given to the vehicle speed sensor (VSS) connection. For
vehicles with a digital signal (square wave, TTL) connecting to the green/white striped
wire will provide a proper signal. In some vehicles (e.g., certain Ford/Lincoln/
Mercury), the vehicle speed signal comes from a variable reluctance sensor which
has a sine wave output. Connecting to the yellow wire will provide a proper signal.
Some vehicles do not have a speed signal that is available to NavMate (e.g., most
vehicles built before 1982, and vehicles with speed signal carried on a bus). Please
call 1-86NAVMATE1(1-866-286-2831) for these vehicles.
2) Route the video cable between the controller mounting location and the display
mounting location.
NOTE: Right angle connector mates to the controller.
