Automobile giants at the world's biggest mobile fair are showing off a new technology that turns a car into a smartphone accessory, allowing a driver to use cutting-edge apps without veering off the road.
Called MirrorLink, and adopted by 85 big manufacturers from Ford to General Motors, Chrysler, Nissan, Honda, Hyundai, BMW, VW, Fiat or Renault, it connects a smartphone and car entertainment system with a two-way audio, video and data link.
MirrorLink requires a compliant car entertainment system and a smartphone with the software, which can be downloaded.
Drivers then can access their favourite apps.
The apps must meet legal requirements for screens that face drivers, for example the text must be a certain size and some functions such as typing must be disabled while the car is moving.
General Motors announced before the show it will embed 4G connectivity in all 2015 model cars in North America.
