OEM telematics is the telematics system built into a vehicle at the factory by the manufacturer (OEM — Original Equipment Manufacturer): the SIM, the connectivity module and the antenna are already on board when the vehicle leaves the production line. It contrasts with aftermarket telematics, where the device is added after purchase.
How it works
On recent connected vehicles, OEM telematics collects and transmits data (location, fuel use, diagnostics, vehicle status) to the manufacturer’s systems with no extra hardware. That data feeds the manufacturer’s apps — and, with the fleet owner’s consent, it can be made available to a third-party platform through Cloud OEM, in line with the EU Data Act.
In short, OEM telematics is the source of the data; Cloud OEM is the channel that delivers it to your fleet management system. For how this works at one manufacturer, see how Stellantis Mobilisights works.
OEM vs aftermarket for fleets
OEM telematics removes installation cost and time and covers the vehicle from day one, but it depends on make and model year. Aftermarket is still needed for older or unsupported vehicles, so many fleets run a mixed setup. In Optivo’s fleet tracking platform the difference is transparent: the data lands in the same dashboard.
FAQ
Are OEM telematics and Cloud OEM the same thing?
No. OEM telematics is the factory-fitted hardware that generates the data. Cloud OEM is the way that data is shared with a third-party platform, over the cloud and with consent.
Do all vehicles have OEM telematics?
No. Most connected vehicles from 2019 onwards have it, but coverage and data availability depend on the make and model.
