Great Onboard Processing Capabilities

Deliver fast responses to complex problems

Whether it is for truck or car fleet management, driver monitoring or ecodriving, our C4 OBD solution is ready to fulfil your technical requirements. With its Arm 11 500Mhz chipset it will run through the most challenging on-board processing demand. 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 OBD-II 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.

Open framework gives you complete access

Deliver tailored solution and rapid time to market

The C4 obd-II dongle runs Morpheus3 OS, so you can directly access parameters such as accelerometer or GPS. The device also comes without pre-embedded application and is entirely programmable using Morpheus3 SDK and its 3000 APIs !


Access third party OBD stacks

Deliver beyond-standard, relevant OBD data analysis

Standard protocols are rapidly proving to be limited for today’s requirements. Mileage, fuel consumption, and the guarantee that the service will work on all vehicles depend on extended EOBD stacks. To simplify access to the multitude of third party stacks, Mobile Devices has created a multi-source EOBD stack with API access 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.


How instant fix makes the difference

• Dramatically reduced Time to First Fix in most environments

• Increased autonomous acquisition sensitivity

• Robust starts and continuous navigation in urban canyons

• Continuous connectivity not required

• No constant downloading – reduced data cost

• Download supported through any connectivity type

• Extended Ephemeris (EE) file valid up to seven days

• Seamless operation between EE file and broadcast ephemeris

• No set up required when connected to CloudConnect
