Hey <a data-id="1203" data-value="Gus_Rubio10" data-denotation-char="@" href="/user/gus_rubio10" class="text-decoration-none mention">@Gus_Rubio10</a> , Great question! Thank you for asking it in our community. There are a few common reasons why a GO device may fail to read the VIN from a vehicle's computer. I used an AI tool to help compile this answer, so please let me know if anything needs clarification. The GO device reads the VIN by querying the engine ECU over the CAN bus. Whether this succeeds depends on how the vehicle manufacturer implemented that part of the ECU firmware. The most common reasons it fails are: - VIN not programmed in the engine ECU — especially after an ECM replacement, the VIN sometimes needs to be manually re-entered using manufacturer diagnostic software and is often skipped - The ECU returns a manufacturer-internal ID instead of the ISO VIN — some manufacturers store an internal build or calibration number in the VIN register rather than the standard 17-character VIN - ECU security lockout — newer ECU firmware versions on some makes require an authenticated diagnostic session before exposing the VIN. Without it, the ECU ignores the request entirely - CAN bus connection issue — if the device is operating in two-wire mode or is connected to the wrong CAN segment, it has no path to the engine ECU It is also possible a loose installation is causing this issue. its hard to say without looking the specific case but I hope this helps give you some things to look into. If the engine VIN cannot be read automatically, the most reliable workaround is to enter it manually in the device settings in MyGeotab. Please let us know if you have any follow-up questions - happy to help! Have a great day! Eishi FUN

¿Why do some GO9 devices not automatically decode the VIN?

Hello. If it is possible to connect the GO device in the bus, I recommend using the following harness: HRN-CW03K3 3-wire harness for GO devices – PWR, GND, IGN.

need to install geotab gps on older bus

The Location is updating correctly, but the Odometer hasnt been updated in 97 days. I have taken out the geotab, put it back in and it works, but the odometer is not updating.

Can a GO9 work in a FRUEHAUF dry van with a 3-wire harness, and what would the considerations be if it is feasible?

Hi everyone, When downloading a requested video from the GO Focus Plus, it appears that the audio track is saved in an independent folder, completely separate from the video file. How can I merge both the video and audio files into a single playback file? Is there a recommended tool or a native method to do this automatically? Thank's in advance!

Hey everyone, Wanted to share some useful info that came up recently around Geotab GO device installations — specifically around antenna orientation and how it affects GPS performance. This information doesn't seem to be commonly known and is CRITICAL for anyone that deals with GO Device Hardware. The Antenna Is Directional and is located on the UNDERSIDE/BOTTOM of the device!Contrary to what you might assume, the internal GPS antenna in Geotab GO devices is directional — not omnidirectional like your phone's antenna. It's physically located on the underside of the device, beneath the printed label/logo.When the device is plugged directly into the OBD-II port under the steering column, the antenna faces downward toward the floor. However, this still works because GPS signals bounce off the asphalt and the vehicle's metallic chassis floor, acting as a reflector. So, although it may not be ideal, it is functional by design for standard plug-in installs. Remember, the designing engineers have to create a product that is as forgiving as possible- the end result is a compromise and results in hardware that is functional in the broadest array of installations/applications. Hidden/Harness Installs? Flip It UpwardIf you're using a T-harness or extension cable to tuck the device inside the dash, the rules change. Geotab's own GO9 support guidelines say you should orient the device with the label/antenna side facing up toward the sky whenever possible. Direct line-of-sight to the satellites overhead gives you: Faster GPS latch times on startupLower Position Dilution of Precision (PDOP)More accurate, consistent tracking data Getting this wrong (antenna pressed against metal, or facing the wrong way in a hidden install) can result in "straight-lining" on your fleet maps — where the system can't get a valid lock and just draws a straight line between the last two known good coordinates. How Glass Affects the SignalThe impacts of vehicle glass is often forgotten or overlooked, but nonetheless critical to performance and stability. Here's a quick breakdown: Glass Type / GPS Impact Standard clear glass / ✅ No impact — GPS passes right throughNon-metallic aftermarket tint (dyed/carbon) / ✅ No impact — signal-safeMetallic/hybrid tint / ❌ Significant degradation — metal particles create a Faraday shielding effectCeramic tint / ✅ No impact — heat-rejecting but signal-friendlyFactory solar/athermic windshields / ❌ Significant degradation — thin metal oxide layer blocks signal If your vehicles have factory "acoustic" or solar-reflective glass (very common in newer model years), be aware that tucking the device under the dash and relying on windshield pass-through may cause issues. Pro tip: Look for the dot matrix zone — the black speckled band typically found near the rearview mirror mount. Manufacturers intentionally leave this area free of metal oxide so that devices like toll passes and telematics units can receive signals through the glass. This is often the best spot to aim for signal penetration. Hope this helps someone avoid a head-scratcher during their next install!Thanks!!!  (Mods: feel free to move if there is a better place for this info to reside)

Hi everyone, What is the exact meaning and operational threshold for the 'GNSS: Signal strength indicated by carrier-to-noise ratio (dBHz) of the strongest satellite signal detected' status record found under 'Engine Measurements' section? Additionally, what are the typical or optimal ranges (in dBHz) for this metric, and what do lower values mean regarding GPS tracking health, signal blockage, or potential interference? Thanks in advance!

Hello, 
I have a client who has asked me if we can adjust the volume of the G09, as her ID isn’t loud enough to encourage her drivers to clock in. 
Thank you

Need to set up ability to use surfsight camera pin number for drivers to be able to  assign themselves to a vehicle in the Geotab database.
Is there a way to do this now?

Hello, I would like to ask what the IOX Smarter AI camera measurement represents on the GO Focus device (0 = Disconnected, 1 = Connected). I appreciate your support in advance. Best Regards!

What does the IOX Smarter AI camera measurement represents on the GO Focus device (0 = Disconnected, 1 = Connected).

We've had trouble viewing the live video from the cameras, as when requesting the live video, the error message "Video Unavailable" appears.

Have you detected any problems with Mygeotab viewing live video from Go Focus?

Hello,I'm looking for clarification on the recommended power/install method for the GO Focus Pro when it is being used alongside a GO9 device.From the documentation, the power consumption between the GO Focus Plus and GO Focus Pro appears to be very close, within only a few milliamps in most modes.GO Focus PlusNominal: 6 W 0.5 A at 12 V / 0.25 A at 24 VParking Mode: &lt;0.4 W 30 mA at 12 V / 18 mA at 24 VDeep Sleep Mode: &lt;0.1 W 7 mA at 12 V / 4 mA at 24 V GO Focus ProNominal: 6 W 0.5 A at 12 V / 0.25 A at 24 VParking Mode: 600 mW 50 mA at 12 V / 2.5 mA at 24 VDeep Sleep Mode: 98 mW 8 mA at 12 V / 4 mA at 24 V My question is: Why can't the GO9 be used to power the GO Focus Pro, especially when the documented power draw is so similar?Also, since the GO Focus Pro has an available OBD-II power harness, HRN-IOXGFPRO-OBD, could an OBD splitter be used so that the GO9 remains plugged into the vehicle's OBD port while the GO Focus Pro receives power from the same OBD connection?In other words, would this setup be acceptable?Vehicle OBD port → OBD splitter → GO9 + GO Focus Pro OBD power harnessOr is hardwiring the GO Focus Pro directly into the vehicle the only approved installation method?I have reviewed the GO Focus Pro wiki/documentation, and I do not see anything that clearly states the device must be hardwired. The documentation also mentions that the GO Focus Pro can be used alongside a GO9, so I'm trying to understand the best/recommended installation approach.Any clarification on the following would be appreciated:Can a GO9 power a GO Focus Pro directly?Can an OBD splitter be used with the GO9 and GO Focus Pro OBD harness?Is hardwiring required, or just recommended?What is the official best practice for installing GO Focus Pro alongside a GO9?Thank you.
