Installing the external Navigator box - SharpX X1S, X2S, XSU

AutoVu™ Navigator box Technote

SharpX X1S, X2S, XSU

To provide Genetec Patroller™ with more accurate geographic coordinates than a standard GPS device, you can install the external Navigator box along with the other AutoVu™ components. Note that if the LPR Processing Unit includes the AutoVu™ Navigation Option, you do not need to install the external Navigator box.

Before you begin

  • Wires to connect the Navigator box to the vehicle's odometry, reverse, and ignition signals are not included. You will need the following:
    • ODO: 24 AWG to 20 AWG shielded, twisted pair (if connecting to the VSS)
    • REV: 24 AWG to 20 AWG stranded conductor copper wire
    • IGN : 24 AWG to 20 AWG stranded conductor copper wire
  • Make sure the you have a flat, level surface to install the Navigator box on.
    IMPORTANT: The Navigator box must be installed parallel to the ground with the mounting ears down. It cannot be mounted upside down (ears up) or on its side.
  • Do not install the Navigator box where it will be in direct sunlight for an extended period of time.

What you should know

  • The Navigator box is a hardware component that interfaces to the vehicle's odometry signal. It also incorporates a GPS receiver and gyroscope for tracking the vehicles position and location.
  • As the vehicle moves, the Navigator box monitors the distance traveled by counting the odometer pulses, and tracks its location using the GPS receiver. The built in gyroscope tracks the vehicles heading in case the vehicle enters a tunnel or parking garage which will block the satellite signal.
  • The Navigator box must be secure and protected from other equipment or moving parts. For example, if you install it in the trunk, you should place it in an enclosure or elevated tray to protect it from being damaged by other items in the trunk, or from water that may leak into the trunk floor.
  • If the system includes an odometry sensor, or if you are installing an odometry sensor to replace an existing magneto coil, see Replacing a magneto coil with an odometry sensor.


  1. Connect the cables and wires at the rear of the Navigator box to your vehicle’s power, ignition, and reverse signals as follows:
    Relays 1 and 2
    Not supported. Do not connect.
    Inputs 1A and 2A
    Not supported. Do not connect.
    Inputs 1D and 2D
    Not supported. Do not connect.
    Ignition input. State of the vehicle’s power system.
    Reverse input. Connect to vehicle’s reverse signal (required for inertial navigation). You can tap into the vehicle’s reverse lights to get this signal.
    - ODO and + ODO
    Pulse odometry. Connect the signal from the VSS.
    • To find the location of the vehicle speed sensor (VSS), consult the vehicles electrical schematic regarding the transmission signals. The schematic will show the location of the vehicle speed sensor (sometimes referred to as the output speed sensor (OSS)).
    • Another location that the vehicle speed signal can be obtained is from the power control module (PCM).
    • Some new model cars, such as hybrids, do not have a output speed sensor and rely on signals from the automatic breaking system sensors (ABS) to calculate the speed and distance a vehicle travels. Do NOT connect to the ABS sensors to obtain a speed signal.
    • If the vehicle does not include a Vehicle Speed Sensor (VSS), you must install an odometry sensor.
  2. On the front of the Navigator box, connect the USB port to the in-vehicle computer’s USB port.
    IMPORTANT: You cannot use a standard USB cable for this connection. Use only the Genetec USB cable (part number: AU-H-USBCBL15).
