Antenna Amp (A2/64)

C  L 

The antenna amplifier(A2/64) receives the signal from the antenna mast (A28). It filters, amplifies and relays the radio, phone and central locking signals. Power for the antenna amp is supplied by N10/2f8 (5A).

N123/4

• Located next to to the the Digital Digital Tele Aid Aid control unit (N123/4) • Splits the signal received from from the GPS antenna (A2/23) (A2/23) • Provides it to the the Digital Tele Aid Aid control unit (N123/4) (N123/4) and to the Navigation module (N41/1). 32

3. Digital Tele Aid Back-up Antennae (A2/54 & A2/55)

The control unit (N123/4) detects faults or poor  reception with the mast  antenna and then switches to  the back-up antennae.

• Back up antenna antennae e (A2/54-left (A2/54-left & A2/55-right) A2/55-right) • Installed Installed at both ventilation ventilation grates in the left and right corners corners of the trunk • If a fault or poor reception reception characteristi characteristics cs are detected detected in the antenna antenna mast (A28), these these antennae are automatica automatically lly selected selected by the 33 Tele Aid control unit (N123/4) .

Backup Antenna Combiner (A2/53)

• Receives Receives and combines combines the signals signals from from both back up antennae (A2/54 & A2/55) • Combined signal signal is transmitted transmitted to the Tele Aid control unit (N123/4). 34
