The Audi phonebox allows drivers to use their mobile phone in the car by placing it in the storage compartment provided in the centre console. A wireless connection is created to the vehicle's roof-mounted aerial via the integrated connector in the storage compartment.
This helps to boost the phone's mobile signal, as well as reducing transmission power. The phone can be charged via a USB port and operated via the MMI control panel, the multi-function steering wheel or voice control.
