Information from one of the BMW navigation systems is just as important: directions are shown either on the Control Display or are available as audio instructions. The Professional navigation system provides extra convenience by allowing you to specify your destination by voice - and also to select the major iDrive functions acoustically. How do you navigate through a library of 10,000 songs? Thanks to the optional USB/audio connection, passengers in the BMW M3 Convertible can access and listen to their entire music libraries. The navigation system displays all the folders and tracks stored on all widely available MP3 players, USB sticks, iPods and mobile phones and the device's functions can be operated using the multifunction steering wheel, the iDrive button or the Professional radio. To protect your device, the optional armrest comes with a choice of one of the different-sized multimedia bags. Bluetooth-compatible mobile phones register with the on-board computer via the optional interface as soon as the driver approaches the vehicle. Telephone numbers, addresses and call lists are then automatically synchronised with the on-board computer. During the journey, the mobile phone can be operated using the multifunction steering wheel or the hands-free equipment. Your local BMW dealer will be happy to inform you of the mobile phones with which the Bluetooth interface is compatible.

These functions include the Digital Motor Electronics (DME system), Dynamic Stability Control (DSC), Electronic Damper Control (EDC), Servotronic steering and the engine. Just one touch of the M Drive button on the steering wheel and all preselected settings are reactivated - for exceptionally comfortable or exceptionally dynamic driving.
