The mobile phone preparation is a hands-free device based on the Bluetooth hands-free profile (HFP). In order to work, the mobile phone must be connected to the hands-free device by means of a model-specific charger cradle or a universal Bluetooth pairing adapter. The charging cradle also links the phone to the external aerial and simultaneously recharges the phone. Optimum voice quality is ensured by a digital sound processor connected to the radio speakers and by a microphone in the headlining.
The mobile phone preparation supports mobile phones that use the Bluetooth profile A2DP (Advanced Audio Distribution Profile). This means that music can be transferred from the phone in stereo quality to the sound system in your Volkswagen.
