The mobile phone is detected/connected in the vehicle within a short period of time when the engine is running or the ignition is switched on.
The phone book entries of the telephone stored on the SIM card* or mobile phone are transmitted to the vehicle after detection, depending on the mobile phone.
Four devices can be paired.
Specific settings may be necessary in some mobile phones, e.g., authorization or a secure connection; refer to the mobile phone operating instructions.
