Voice connection to vehicle, function - GF82.95-P-2006RM

MODEL 230.4 as of 1.7.04 with CODE (359) TELE AID emergency call system with CODE (494) USA version 

Regardless of the type of emergency call made, after the SMS has been sent, a voice connection is immediately established to the service center and the user can speak with a service receptionist. If the service center cannot establish a connection to the vehicle, the emergency call system control unit (N123/4) attempts to establish a connection from the vehicle to the service center. Both emergency call and the info services are provided free of charge by Mercedes-Benz customer service.

The hands-free system microphone group (A67b1) is used for voice input. Voice output occurs exclusively over the left front emergency call speaker (H4/46) and the right front emergency call speaker (H4/47). Both speakers are actuated discretely by the emergency call system control unit (N123/4). Normally, the telephone connections are established via the telephone antenna (A2/22). If the standard telephone antenna should happen to malfunction (A2/22), such as due to the a vehicle rollover, there is also a TELE AID backup antenna located in the area of the rear shelf (A2/50). The emergency call system control unit (N123/4) detects the failure of the telephone antenna and then automatically actuates the TELE AID backup antenna (A2/50).
