This operating mode is mainly intended for
those using multiple SIM cards. As soon as
the mobile phone associated with the SIM
card is connected with the multimedia sys‐
tem in the vehicle, the SIM card is automati‐
cally activated for business telephony. The
association of the SIM card with the set
mobile phone prevents automatic activation
of business telephony via the SIM card if the
vehicle is borrowed by other persons, for
