Warnings
⚠︎ Professional Installation Required — Installation of this product requires that the installer have sufficient technical knowledge and expertise for installation and integration into modern vehicles, i.e. Certified Geotab Installer certification or equivalent.
! 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 reconnect it after installation (see link). Failure to follow these instructions and warnings can result in loss of vehicle control and serious injury or vehicle damage.
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! Ensure the GO Focus Pro is installed securely and the installation location does not affect the driver’s visibility to see the road, mirrors, or vehicle controls. Failure to do so may interfere with vehicle operation resulting in property damage, collisions leading to death or serious personal injury.
! IMPORTANT: The GO device must be disconnected from the vehicle prior to installation.
Important Safety Information and Limitations of Use
For the latest version of the Limitations of Use, please visit: https://gtb.link/k6Fp0w.
You must always select the right Telematics hardware suitable for your specific installation environment and vehicle use.
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.
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.
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! 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! 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.
Windshield Placement: Performance and Legal Compliance
Overview
- The guidance below describes the recommended placement for optimal camera performance. It is general information to help you install the camera effectively. It is not legal advice, and it does not determine what is lawful in your location.
- The vehicle owner and the installer are responsible for selecting a final mounting position that complies with all applicable windshield-obstruction and device-placement laws for the vehicle’s class and operating region(s). Where the best-performing position is not permitted by local law, local law governs.
Recommended placement for optimal performance (all regions)
- Mount the camera as high and as close to the vertical center of the windshield as practical (typically directly behind or beside the rear-view mirror) so the road-facing lens has a clear, centered view of the road ahead and the driver-facing lens (if equipped) has a clear view of the cab.
- Keep the road-facing lens within the area swept by the windshield wipers so that rain, snow, and debris are cleared from the camera’s view.
- Keep both lenses clear of obstructions such as stickers, heavy tint bands, VIN plates, toll transponders, and factory-installed sensor or camera housings (for example, ADAS or rain-sensor modules) behind the mirror.
- Position the camera so it does not block the driver’s view of the road, signs, or signals, and mount it outside the driver’s primary line of sight.
- Keep the camera body and cabling clear of airbag deployment paths, including roof-rail and curtain airbags routed through the A-pillars and headliner.
- Before removing the adhesive backing, use the Geotab Video app live preview to confirm framing (driver’s head centered in the on-screen guide; horizon aligned in the road view), then verify the final position.
Confirm and follow local placement laws
- Most jurisdictions restrict what may be mounted on a windshield. A near-universal requirement is that nothing may materially obstruct the driver’s field of vision. Many jurisdictions also regulate the specific area of the windshield where a device may be placed and/or the maximum size of the device, and some rules differ by vehicle class (for example, light-duty vehicles versus heavy commercial vehicles).
- Because these requirements vary and change over time, confirm the current rules that apply to your vehicles and operating region(s) before installing, and select a compliant mounting position. Consult your own advisors where needed.
- Some jurisdictions have more specific or more stringent placement requirements than others. The official sources below are provided for convenience and as a starting point only. They are not exhaustive, do not describe every applicable requirement, and are not a substitute for confirming the current law that applies to you:
- United States (commercial motor vehicles): 49 CFR § 393.60 (FMCSA)
- California: California Vehicle Code § 26708
- Canada (set provincially; rules vary by province): Ontario Highway Traffic Act
- United Kingdom and Europe (rules vary; often based on a general driver’s field-of-vision standard): UK Department for Transport guidance
If the recommended position is not permitted where you operate, prioritize compliance. Choose the position within the legally permitted area that provides the clearest usable view for both lenses.
Note: This placement guidance is general best-practice information, is current as of June 2026, and is not legal advice. Windshield-obstruction and device-placement laws vary by jurisdiction and vehicle class and change over time. The vehicle owner and installer are responsible for compliance.

NOTE: ⚠︎ Do not remove the adhesive strip until you are directed to do so in the app.
NOTE: Before finalizing the mounting position:
- Lower the sun visor completely to ensure it doesn't block the camera's view
- Ensure that the rear-view mirror does not block the camera’s view of the driver’s face
- WARNING! Do not mount the camera directly in the path of any airbag deployment zone. Before mounting, consult the vehicle owner's manual to confirm the airbag deployment zones for that vehicle.
Attach the mounting bracket
Attach the mounting bracket to the back of the GO Focus Pro device. Push the bracket in until you hear a click.
⚠︎ Do not remove the adhesive strip yet.

Attach I/O cover
After the GO Focus Pro has been properly mounted, attach the I/O cover to secure the cable.

Hide visible wiring
Route the cable behind the A-pillar trim seam and into the door rubber weatherstrip, keeping the cable clear of the roof airbag deployment zone.
WARNING! Do not route the cable under the roof headliner in vehicles equipped with roof-mounted airbags, as doing so may interfere with airbag deployment. If you are unsure whether the vehicle has roof-mounted airbags, consult the vehicle owner's manual before installation.

Review the installation report
After completing the camera installation and configuration, the installation report will be available in the Geotab Video app.
