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

MODEL 215.3, 220.0 /1 with CODE (383a) Tele-Aid fixed installation telephone with CODE (494a) USA version 

Irrespective of the type of emergency call, a voice connection is established to the service center immediately in parallel to transmitting the SMS and the user can talk to a service receptionist. If the service center is unable to establish a connection to the vehicle, the telecommunications control unit (N112) itself tries to establish a connection between the vehicle and the service center. Both, the emergency call and the information service are free services provided by Mercedes-Benz customer support.

The hands-free system microphone group (A67b1) is used for the voice input. The voice output occurs exclusively via the left front speaker (H4/9) and the right front speaker (H4/10). Both speakers are actuated discretely by the telecommunications control unit (N112). Usually, the telephone connection is established via the telephone antenna (A2/49a1) (model 220) that is located at the rear window, or via the telephone antenna (A2/22) (model 215) at the tailgate. If the telephone antenna (A2/22) (model 215) or the telephone antenna (A2/49a1) (model 220) is defective, e.g., in the event of a rollover, 2 emergency antennas are available in the rear bumper of the vehicle, which are called emergency call system left backup antenna (A2/54) and emergency call system right backup antenna (A2/55). The telecommunications control unit (N112) detects the antenna failure and consequently actuates the emergency antennas automatically.
