Full Technical Specifications

Deliver fast responses to complex problems.

Whether for truck or car fleet management, driver monitoring or ecodriving, our C4 OBD2 solution is ready to fulfil your technical requirements. With its Arm 11 500Mhz chipset, it will run through the most challenging on-board processing demands. On top of that, it can include GPS positioning, GPRS connectivity, 3 axis Gyro and Accelerometer, Bluetooth connectivity and an emergency battery.

Unbeatable GPS reception from inside the vehicle.
Deliver location precision from a plug-in solution.

With the C4 OBD2 Dongle, you get unparalleled location precision from inside the cockpit. With its updated SiRF AtlasV chipset, GPS Assistance technology (see below) and innovative internal antenna design, this is a powerful smartbox ready to send location data in less than 10 seconds.

Access third party OBD stacks
Deliver beyond-standard, relevant OBD data analyses

The C4 OBD2 Dongle supports a wide array of standard protocols from the starts. If the standard protocols are not adapted to suit your requirements you need extended EOBD stacks. To simplify access to the multitude of third party stacks, Mobile Devices has created a multi-source EOBD stack and an open market for third party providers.

Unique multisource OBD stacks

Thanks to Morpheus3 OS, service providers can open the device to third party OBD stack providers. This means that solutions, such as ecodriving or odometer can be implemented based on the instant consumption and absolute metering data from the OBD.

The third party stack providers get absolute IP protection (encapsulated communication protocol) and revenue generation based on a marketplace model.
