CONTENTS
■
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)
OPERATION
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.
SETUP
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.
