IOX Installation Instructions

! IMPORTANT: Professional installation (Certified Geotab® Installer or equivalent) is required for the safe and proper installation of this product (harness and/or IOX). The installer must have sufficient technical knowledge and expertise for the respective installation.

WARNING! Always read and follow all safety information, including Important Safety Information and Limitations of Use, before harness and/or IOX installation. Disconnect the GO device from the vehicle before installation and connect it post-installation (see Failure to follow these instructions and warnings can result in loss of vehicle control and serious injury or vehicle damage.

✱ NOTE: It is recommended that the GO device and the IOX-KEYLESS are installed in a vehicle with an appropriate T-harness to install the devices away from the OBD port (to reduce the risk of accidental unplug). The T-harness is also used to install another device into the OBD port without having to remove the GO9 device. The most common harness is the HRN-GS16K22 - harness installation depends on the vehicle. Please refer to the appropriate installation instructions for install.

✱ NOTE: IOX-KEYLESS is NOT compatible with the IOX-BT.

How to Install IOX-KEYLESS

See video How to Perform an Advanced IOX-KEYLESS Installation.


Unplug the Geotab GO device from the vehicle and remove the IOX expansion port cover on the GO device.


Plug the 90° USB connector from the IOX into the GO device. Secure the USB connector using a cable tie. Please note that over tightening the cable tie may damage the USB connector.

NOTE: Insert the USB connector in the orientation displayed in the image.


Choose an appropriate location to mount and conceal the IOX. The IOX can be mounted underneath the dashboard trim — as shown in the image to the right — or attached directly to the trim, vehicle frame, or to a wire bundle as seen below. Use the existing cable tie locations on the IOX casing to attach the IOX to the vehicle.

NOTE: Choose an area where the IOX-KEYLESS does not interfere with the safe operation of the vehicle. Keep the routing of the IOX wire in mind when choosing a location for the IOX casing.

The IOX can be mounted in vertical or horizontal orientation — depending on the target vehicle for installation.


Once you connect the IOX-KEYLESS to the GO Device, plug in the GO Device and immediately start the vehicle. The GO Device will enter debug mode.


Once the device is connected and receives power, the LEDs on the front of the device start blinking then turn solid once completing the actions below.

Red LED — Device configuration

Green LED — Cellular network connectivity

Blue LED — GPS network connectivity

The device emits two quick beeps every 60 seconds during setup. Initial startup may take several minutes to complete.


Navigate to to verify that the device is communicating. In the space provided, enter your name, the company name, and the GO Device serial number — found at the bottom of the device. Click Log Install.


After you click Log Install, the web page displays the current communication status of the device — in GREEN or RED text. If the device is communicating, the status is displayed in GREEN text. If the device is not communicating, the status is displayed in RED text.

NOTE: If the device is not communicating, ensure the GO Device is installed correctly and try again.

Termination Shunt

The IOX comes with a termination shunt installed in the expansion port. If you plan to install more than one IOX in a daisy chain, you must remove the shunt from each device in the line, except for the last IOX connected. The shunt must remain in the last IOX and secured with a cable tie.

The shunt in the last IOX device ensures the GO device detects and configures the IOX as effectively as possible.

NOTE: Failure to install the shunt in the last IOX may affect IOX communication. To ensure the IOX communicates, please secure the shunt with a cable tie.

Important Safety Information and Limitations of Use

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

WARNING! Do not attempt to install, configure or remove any product from any 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 units while being operated could result in malfunctions or accidents, leading to death or serious personal injury.

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. You must inspect devices and cabling on a regular basis to ensure all devices and cabling continue to be securely attached. Loose cabling or devices may impede the use of vehicle controls, resulting in unanticipated acceleration, braking or other loss of vehicle control, which could lead to death or serious personal injury. Improperly fastened in-vehicle devices may detach and impact operators upon sudden acceleration or deceleration, which may cause injury.

WARNING! If at any point after an in-vehicle device is installed a warning light illuminates 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.

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 or vehicle damage 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 death or 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.
