I am sure you all enjoy your cars the way you would like to. Look to a 36 month window before most luxury vehicles have some type of touch screen multi-level product intergration....

OEM headunits will be a thing of the past. Steering wheel controls standard. GUI interface will drive the system with realtime travel weather, xm radio, and satelite nav and DVD. Emergency program buttons for hospital navigation and authorties closest to your location (using satelite geo cordinates) One unit will do everything. It will be rolled out very soon in several SUV brands and then most other vehicles within five years.

Bosch and Becker have been working on these units for Merc, BMW and Volkswagen. Ford is on the wagon too here in the states.
