Geotab® GO8® — Expandable Simple-to-Install Telematics Device (Discontinued)

For the most up-to-date version of this document, visit:


GO8 device

GO8 is a small yet extremely powerful telematics measurement tool. Similar to the GO7® before it, the GO8 offers state-of-the-art GPS technology, g-force monitoring, GEOTAB IOX® expandability, and engine and battery health assessments, with the added feature of communicating on the LTE network.

Vehicle tracking

Using Geotab’s patented tracking algorithm, the GO8 accurately recreates a vehicle’s trips and analyzes its incidents. Moreover, the GO8 offers in-vehicle alerts to instantly notify drivers of infractions and — with hardware Add-Ons — the ability to provide live coaching to drivers relating to their on-road performance. The GO8 is simple to install and does not require a dash-mounted antenna or any splicing of wires.


Geotab platform security is designed for end-to-end protection of your data.

Key implementations include:

  1. GO device and network interfaces use authentication, encryption, and message integrity verification.
  2. GO devices are individualized. Each device uses a unique ID and non-static security key, making it difficult to fake a device’s identity.
  3. Over-the-air updates use digitally-signed firmware to verify that updates comes from a trusted source.
  4. Geotab uses independent third-party experts to validate the platform from end to end.
  5. FIPS 140-2 validated by NIST (certificate #3371)

    Preparing for installation

    Before installing your device, please record your device serial number. You will need this information at a later time to verify your installation.

    1. Verify that we support your vehicle by carefully reading the device release notes at or from the vehicle specific installation notes at If you have any questions or concerns, please consult your Authorized Reseller.
    2. Ensure no dash warning lights are on in the vehicle while it is running, and all other functions such as headlamps and flashers etc. are working prior to installing the device.

    Installation instructions

    Read important related safety information and limitations of use following these installation instructions. Read and follow all instructions and warnings to prevent serious injury and/or vehicle damage.

    WARNING! Prior to GO™ installation, read and follow important safety information including limitations of use located following these installation instructions. Always read and follow all safety information to prevent loss of vehicle control and serious injury.

    WARNING! Some installations are not straightforward and must be completed by an Authorized Geotab Installer to ensure a secure installation. An unsecure device installation can cause poor electric and/or data connection that can lead to short circuits and fires or cause malfunctions of vehicle controls that can result in serious personal injury or significant damage to your vehicle. Some examples requiring professional installation from an Authorized Geotab Installer are:

    1. The OBD port location is such that the device protrudes and interferes with entering or exiting the vehicle, or located where it could be inadvertently kicked or bumped during vehicle operation
    2. The device is not fully secured and so may come loose with vibrations or accidental contact
    3. An electrical harness or additional wiring is required
    4. Vehicle mounting modifications are required to secure the device (removing of panels; deformed or damaged OBD connector; or physical damage to the electrical wiring)
    5. The device does not beep six times and power on when first installed
    6. The installer questions their ability to complete a secure installation according to these instructions

    WARNING! Do not attempt to install, reconfigure, or remove any product from a vehicle while the vehicle is in motion or otherwise in operation. All installation, configuration, or removal must be done only in stationary vehicles which are securely parked. Attempting to service devices while the vehicle is in motion could result in malfunctions or accidents, leading to death or serious personal injury.

    Installing the GO Device


    Locate the vehicle’s engine diagnostic port, typically found in the driver’s area at or below knee level.

    Note: Heavy-duty vehicles use a different connector system. Contact your Authorized Geotab Reseller for heavy-duty connector applications or for extension harnesses should it be necessary to place your device away from the engine diagnostic port.



    Align the receiver end of the device with the engine diagnostic port and simply push in place, ensuring that the device is well connected to the diagnostic port. You will hear 6 quick beeps and all three lights on the device will flash briefly.

    A user is plugging a GO device into a vehicle's engine diagnostic port.


    With the vehicle parked outdoors to locate satellites and vent exhaust fumes, start the vehicle and allow it to run for approximately 3 minutes. During this period you will notice the Red LED power on and glow on the face of the device. Shortly afterwards the Green and Blue LEDs will light up when the device connects with the cellular and GPS networks. This initial startup may take several minutes to complete.

    Once all three LED lights have lit up, secure your device using the supplied cable tie.

    When performing under-dash installations with an extension harness, make sure the antenna side is always pointing upwards towards the sky for faster GPS latch times. The GPS antenna in a GO8 is located on the bottom side of the device.


    Please verify that the device is communicating correctly. Using a PC or smart phone, navigate to

    Fill in your name, company, and the Geotab GO device serial number (found at the bottom of the device) and click on Log Install.

    Screenshot displaying fields for Installer Name, Installer Company, Device Serial No, Odometer, and Asset Number on


    You will now see a screen that displays the current status of the device. If the device is communicating correctly, you will see GREEN lettering with the last valid GPS record. If the text appears in RED, the device is unable to communicate and you must verify the installation.

    WARNING! All in-vehicle devices and related cabling must be securely fastened and kept clear of all vehicle controls, including gas, brake and clutch pedals. This requires the use of a cable tie when securing the device or any extension harness to the OBD connector, securing both sides of the harness. If you do not use a cable tie, vibration in the vehicle can lead to a loose connection which could indirectly cause the vehicle’s engine computer to fail, loss of vehicle control and cause serious injury. Inspect devices and cabling regularly to ensure all devices and cables remain securely attached.

    WARNING! If at any point after an in-vehicle device is installed a warning lights up on the vehicle dash or the vehicle stalls or has a marked drop in performance, shut off the engine, remove the device, and contact your reseller. Continuing to operate a vehicle with these symptoms can cause loss of vehicle control, and serious injury.

    Important safety information and limitations of use

    For the latest version of the Limitations of Use, please visit:

    WARNING! Your in-vehicle devices must be kept clear of debris, water and other environmental contaminants. Failure to do so may result in units malfunctioning or short-circuiting, that can lead to a fire hazard and cause loss or serious injury.

    WARNING! Do not attempt to remove the devices from the vehicle in which they are originally installed for installation in another vehicle. Not all vehicles share compatibility, and doing so may result in unexpected interactions with your vehicle, including sudden loss of power or shutdown of the vehicle’s engine while in operation or cause your vehicle to operate poorly or erratically and cause serious injury and/or vehicle damage.

    NOTICE: This product does not contain any user-serviceable parts. Configuration, servicing, and repairs must only be made by an authorized reseller or installer. Unauthorized servicing of these products will void your product warranty.
