TomTom devices gives access to engine info for smartphone use

TomTom Business Solutions is launching a new device the TomTom Link 100. This connects to the engine management unit (EMU) via the standard CAN-bus and has a built in 3D accelerometer. This then can connect to a smartphone device via Bluetooth allowing easy diagnostics in the event of a crash or even the vehicle breaking down.

All modern cars use the standard bus interface so it should work will most cars on the road.

The device can also be used by insurance companies to track driving habits etc (though no GPS information is available), drivers could also use the device to improve their driving.

TomTom have not said what data is exposed (apart from RPM, load and temperature), though the EMU provide a lot more information and with the right application many minor faults can be reset by such a device making trips to the garage less frequent (and also allowing drivers to check what faults garages etc are charging them for and whether it is a major or minor fault).

If the all the data is exposed and TomTom allow read and write information it could allow app vendors to make interesting solutions to make the driving experience better, though of course insurance companies will want these devices to ensure drivers drive better.

TomTom support not so supportive

Recently my TomTom GO910 computer voice stopped working even though upgrades etc had taken place using the supplied TomTom Home software. The pre-recordered voices worked fine, only the text-to-speech system from Loquendo seemed to have failed.

After logging a support incident with TomTom, they recommended removing the LogquendoTTS directory from the device and then a long protracted support dialogue took place. After backing-up several directories and performing various set-up steps an email came in asked to restore the LoquendoTTS directory that had been deleted (before any back-ups were requested).

Now the unit has to go back to TomTom at their expense, but even so it means not having a navigation device for a while. Not the most optimal use of my time and a bit of a support failure.
