Carphones could be set to make a comeback, but they've come a long way since the bricks of the 1980s. Soon they may even be able to help catch car thieves.
Audi on Wednesday revealed an iPhone-like mobile phone that also doubles as a portable music player and enables the owner to unlock his or her car with no key, or turn on the sound system or heating from the comfort of home.
The device can also alert car owners in the event of a theft and even transmit a picture of the thief to the phone.
