navigating when using an in-car navigation system.
In-car navigation systems are common and many drivers use them regularly. Typically,
three types of systems are in use: (1) built-in systems offered by the manufacturer
(2) specific navigation add-on devices offered by third party companies, and (3) navigation
applications on mobile phones which include GPS. Sales trends show that these
devices are increasingly being used and that it will be the norm to use a navigation system
within the next few years1.
