■
Digital (standard):
☞
Route the black/white A1 cable of the
wiring harness to the speedometer signal
pick-up point. Refer to the vehicle-specific
data sheets for location and connection
details (available on CD-ROM).
Digital speedometer signal requirements:
❑
Frequency: 0 Hz - 4 kHz square-wave
signal (no inductive sensor)
❑
Low - level: < 1 V
❑
High - level: 4 V - 24 V
■
Analogue (for retrofitted speedometer
senders and magnetic sensors):
☞
Connect the short black/white A3 cable
(directly at ISO chamber A connector) of
the wiring harness to the output of the
speedometer sensor or the magnetic
sensor.
■
Operation without speedometer
signal
Operation of the navigation system is possible
without a speedometer signal. However, in
the absence of a speedometer signal the fol-
lowing functional restrictions may arise:
❑
Inaccurate navigation
❑
Inaccurate or invalid information in trip
computer
❑
Limitations with regard to SDVC (speed-
dependent volume control)
Other signals (ISO chamber A):
☞
Connect the white/yellow wire (A2) to a
suitable point of the reversing signal
lead (positive lead of reversing lamp).
☞
Connect the grey wire (A6) to a suitable
point of the low beam (not to the dash
panel illumination!).
✎
Connection to the dash panel illumina-
tion may result in malfunctions of the
navigation system (e.g. extremely slow
reactions to operating steps and system
crashes.).
Connecting system components
(ISO chamber B)
■
Active remote control holder
RCD 5400 (accessory):
☞
Connect the remote control cable plug
to the mini-DIN socket on the signal
cable.
■
Loudspeaker (accessory):
☞
If required, connect separate loudspeaker
to signal cable (B5 and B6). The loud-
speaker impedance should be between
4 and 8 Ohm.
■
Loudspeaker mute/MUTE (option):
☞
Connect the brown/white wire (B4) of
the signal cable to the MUTE input of
the car radio.
Playback of voice messages via the
vehicle loudspeaker
For playback of the acoustic guidance in-
structions via the front left vehicle loud-
speaker, an MA 1300 adapter cable (acces-
sory) can be connected between the loud-
speaker lead and the audio output of the
navigation computer.
☞
Connect the brown/white wire (B4) of
the signal cable to the MUTE input of
the adapter cable.
