  Just as the world of consumer devices was forever changed by the introduction
of computer controlled solutions, the introduction of the engine control unit
(ECU) gave rise to the automobile's transformation from a transportation
product to a technology platform. A modern car is capable of processing,
analysing and transmitting data in ways that could not have been foreseen only
a few years ago. These cars often incorporate telematics systems, which are
used to provide navigation and internet connectivity over cellular networks, as
well as data-recording devices for insurance and product development purposes.
We examine the telematics system of a production vehicle, and aim to ascertain
some of the associated privacy-related threats. We also consider how this
analysis might underpin further research.
