Overview
For new series 7 vehicles with existing telephony equipment (option code 633 or option code 644), the BMW Group offers the rear-seat telephone unit with cordless handset* (option code 6NB). The option code 6NB can optionally be operated via the SIM card of a GSM carrier or mobile phone that supports the SAP (SIM Access Profile) Bluetooth® profile.
Option code 6NB includes a Snap-In Adapter with GSM module? with the slot for a SIM card as well as the cordless handset. As standard, both components
are built into the centre armrest. The GSM Snap-In Adapter is thereby directly connected to the external aerial of the vehicle.
