General 

Antennas are located at various positions around the vehicle depending on the function and task involved.

Function 

The antenna connection to the respective control units, antenna splitters, amplifiers and receivers is different depending on the function, equipment and body form.

Telephone antennas connection 

The driver's side telephone antenna (4) and the front passenger side telephone antenna (5) are connected to the telephone antenna splitter (10). Depending on the vehicle equipment, the antenna connection may differ:

• Vehicles with code 899 (Multifunction telephony) or  with code B24 (Remote control for auxiliary heating):

  Via a simple telephone antenna splitter (10) directly to the mobile phone cradle control unit or stationary heater radio remote control receiver (9)

• Vehicles with code 899 (Multifunction telephony) and  with code B24 (Remote control for auxiliary heating):

  Via a 2-way telephone antenna splitter (10) to the mobile phone cradle control unit and stationary heater radio remote control receiver (9)

On vehicles with code 899 (Multifunction telephony), the antenna signal to the mobile phone cradle control unit is amplified by the cellular telephone system antenna amplifier/compensator (11).

Emergency call system antennas connection 

The emergency call system 1 antenna (21) and emergency call system 2 antenna (18) are directly connected to the telematics services control unit.

GPS antenna connection 

Depending on the vehicle equipment, the following connection options are available for the GPS antenna (6):

• Vehicles with code 362 (HERMES - communication

  module LTE) without  code 355 (Extended MBUX functions):

  Directly to the telematics services control unit

• Vehicles with code 362 (HERMES - communication module LTE) with  code 355 (Extended MBUX functions):

  The antenna signal is forwarded to multimedia system control by a GPS splitter integrated into the telematics services control unit.

• Vehicles without code 362 (HERMES - communication module LTE) but with code 355 (Extended MBUX functions):

  Directly to multimedia system control

Rear window antennas connection 

The antennas in the rear window are connected via 2 antenna amplifiers:

• FM, AM, ZV, DAB and KEYLESS-GO antenna amplifier (20)
• FM2, DAB and TV2 antenna amplifier (19)

Windshield antennas connection 

The antennas in the windshield are connected via 2 antenna amplifiers:

• TV 1 antenna amplifier (8)
• TV 3 antenna amplifier (7)

Rear spoiler antenna connection 

The antennas in the rear spoiler are connected via the FM, AM, ZV, DAB and KEYLESS-GO antenna amplifier (20).
