Audi are bundling in a mobile phone with the new Audi A1. This isn't just any phone however, once plugged into the car it controls GPS, audio/video, keyless ignition amongst other cool functions.
It is a common practice for leading car producers to manufacture cars with tight integration of mobile phones for benefiting the navigation, multimedia, security and other functionality - the last example of the result of such cooperation is the Renault Twingo Nokia edition with included Nokia 6110 Navigator.
Audi apparently not satisfied with this sort of cooperation, have introduced their own concept device dubbed the "Audi Mobile Device", a mobile phone that also takes full control over the car (please, don't lose it).
