With Code 347, 348 or 352 (Comand and/or Tele-Aid)

GPS antenna (A2/49a2)
The satellite signals received are amplified by the antenna amplifier integrated in the GPS antenna (A2/49a2). This is supplied with voltage via a co-axial antenna cable (phantom supply). The amplified signals are then conveyed via the same coaxial antenna cable to the integrated GPS control module:
- for code 347 or 348, in the TELE AID control module (A35/8)
- for code 352, in the COMAND operating, display and control module (A40/3)

If the vehicle is equipped with TELE AID and COMAND, the coaxial antenna cable of the GPS antenna (A2/49a2) is routed to the antenna splitter (A2/5). In turn the control modules (A35/8) and (A40/3) are connected to the two co-axial outputs of the antenna splitter.

The GPS antenna only serves to receive GPS signals (no signals are transmitted).

CTEL antenna (A2/49a1)
The signals received by the A2/49a1 are conveyed via a separate co-axial antenna cable as follows:
- for code 347 or 348, to the TELE AID control module (A35/8)
- otherwise direct to the CTEL transmitter and receiver (A35) or to the portable CTEL (A34/6)

The converse applies to the transmission of signals.


NOTE: The GPS reception frequencies are in the GHz range and the cellular telephone reception and transmission frequencies are in the MHz range. Each antenna is connected to the corresponding receiver via a separate co-axial cable.
