From First Plug-In to Full Rollout
You do not get a ticket number, you get a U.S.-based team, from first install to day-to-day tuning.

Device Installation Support
Before the box ships
Most install problems are really harness problems, so we solve them before anything ships, not under the dash.
A standard GO9 is itself a 16-pin device; on 16-pin OBD II vehicles with a 12V system it usually plugs straight in. Where a harness is needed, a universal T-harness keeps the diagnostic port free.
Freightliner, International, Kenworth, Mack, Peterbilt, Volvo, Western Star and the rest are matched to the correct harness by make, model, and year. Both OBD II and RP1226 diagnostic ports are supported.
24V vehicles and 12V Volvo and Mack engine vehicles get a heavy-duty adapter with the 16-pin universal harness, per Geotab's product advisory. You do not need to know that; we do.
Dedicated HRN-R series weatherproof harnesses, never a standard one that "probably fits."
Older hardware predates today's harness standards, so we confirm the right current harness for your make and year as part of the upgrade. Cheap insurance against a mystery no-power call.
Use only Geotab-approved harnesses from authorized channels. Non-approved cables are a documented fire and injury risk, and we will not install one.
California fleets: every applicable install includes placing the CARB Executive Order (EO) label in the engine compartment near the emission control label, so the vehicle passes its Smog Check inspection without a conversation.
Ready on arrival
Everything ships matched to your vehicles and pre-checked. No guesswork under the dash.

Geotab GO9 / GO10
Plug the device into your vehicle's OBD II port, or use an adapter where needed. No antenna, no wire-splicing, and it auto-calibrates in any orientation. Most GO installs take minutes with no installer and no appointment: you plug in, listen for the beeps, and call us to confirm it is reporting.

Make sure the device is firmly plugged into the diagnostic port. Check for blown fuses or an inactive vehicle battery, and try another vehicle port.
The device may still be configuring. Wait 5 to 10 minutes, then unplug for 30 seconds and reconnect.
Relocate the device to reduce interference. Avoid installing beneath metal panels or near heavy wiring. With a harness, keep the antenna side facing upward toward the windshield or sky.
Contact support@gpsfms.com or call (877) 771-2236 and we will verify communication to your database.
Geotab GO Focus
The camera auto-pairs with your GO device and self-calibrates once it is powered on. Because it wires into the GO device through the IOX port, GPSFMS coordinates a certified installer and confirms the camera is reporting before the job is done.

Check the camera is securely seated in its bracket, the IOX cable connection is solid, and the GO device is powered and communicating.
Confirm both the GO device and GO Focus serial numbers are registered in MyGeotab, then contact GPSFMS to verify data sync.
Check the IOX cable is properly connected and free of damage. Re-seat both ends and restart the vehicle. If it persists, contact GPSFMS.
Press and hold the red camera SOS button for 5 seconds to re-enable Wi-Fi pairing mode. GPSFMS can remotely guide calibration.
Geotab GO Rugged
GO Rugged is sealed and hardened for off-road and outdoor equipment, with IP68/IP69K-rated connectors. Because it is a hardwired install, GPSFMS coordinates a certified installer and confirms it is reporting before you sign off.

Check the harness is securely connected and power is reaching the device. Look for a blown fuse or inactive battery, and inspect the harness connector for dirt, corrosion, or loose pins.
Verify power and ground connections are tight, confirm the device is registered to the correct vehicle in MyGeotab, then restart the vehicle and recheck.
Avoid mounting near heavy wiring, metal panels, or high-vibration zones. Inspect for damaged cables or loose mounts. GPSFMS can remotely verify the network connection and assist with placement.
Wait up to 15 minutes for first-time setup. If still offline, contact GPSFMS Support at support@gpsfms.com or (877) 771-2236.
Geotab GO Anywhere
No wiring, no charging, no tools. Attach it, activate it, and it reports for 3 to 5 years on the base GO Anywhere's 3,100 mAh battery.

Confirm the activation magnet is fully removed and move outdoors for strong GPS. Contact GPSFMS if no LED appears within 1 to 2 minutes.
Verify signal coverage and placement with the label facing the sky, and confirm the serial number is correctly added to MyGeotab. Reapply the magnet for 5 seconds, then remove it to retry activation.
Avoid mounting beneath metal panels or in poor-signal areas, and keep the device stationary during activation. GPSFMS can verify connectivity remotely and suggest optimized placement.
If the device reports low battery or stops updating, contact GPSFMS for a diagnostic review and replacement options.




Cameras and add-ons
Every add-on, camera, driver ID reader, spoken-alert speaker, or sensor interface connects through the GO device's IOX port and daisy-chains, so one clean install carries the whole stack. The rules that keep it clean:

Questions
GO devices are genuinely self-install on most light-duty vehicles: plug in, listen for the beeps, call us to verify. IOX add-ons, cameras, and GO Rugged harness installs are professional jobs, and we coordinate certified installers when your fleet needs them.
Vehicle make, model, and year, per unit. That is enough to confirm the device, the harness or adapter if any, and the configuration, so what arrives matches what is in your yard.
Yes: do not reuse the old provider's cables. Devices only ship and install with Geotab-approved harnesses, and if you are coming off older GO8-era hardware, the harness gets replaced along with the device.
