How It Works  The Bluetooth handset engaged in the eject box is released by pressing the eject button. Lifting one side of the Bluetooth handset enables it to be removed more easily from the eject box. When the Bluetooth handset is engaged, the contacts on the Bluetooth handset and the contacts on the eject box touch. The connection to the integrated charger in the eject box and to the Telematic Control Unit (TCU) is established via the contacts.

NOTE: Activating the telephone functions. The "Professional car phone" functions can only be used when the SIM card is inserted, with the exception of emergency calls.
