Safety instructions
Installation and connection regulations
While installing and mounting this equipment, you must
disconnect the negative terminal of the battery. Important: You
must also comply with all safety instructions given by the auto
manufacturer (alarm system, vehicle immobilizer, airbag)!
Before drilling holes for mounting the equipment or laying the wiring,
make sure that no existing wiring or auto parts (such as the petrol
tank, fuel line) will be damaged.
Use wire bushings on sharp-edged holes.
In order to avoid any interference, lay all wiring far enough away
from the wire harnesses.
Equipment fuses:
Basic unit: 5 A wire fuse
5 A miniature fuse
GPS receiver: 5 A wire fuse
Magnetic field sensor (electronic compass)
Note: You must determine the optimum mounting location for
the magnetic field sensor in each vehicle individually. Before
permanently installing the magnetic field sensor, attach it
temporarily and then test the chosen location with the installation
and calibration CD-ROM to make sure everything operates
correctly.
The magnetic field sensor must be installed in the passenger room. It
determines the driving direction by measuring the horizontal earth
magnetic field component. Since the earth magnet field is relatively
small, you must ensure that there is no magnetic or electromagnetic
interference affecting the magnet field sensor at the chosen mounting
location.
Use the enclosed mounts to attach the magnet field sensor to a window
which cannot be opened or, especially where estate wagons or liftback
cars are concerned, mount it without fasteners underneath the inside roof
lining using double-sided sticky tape.
Note: If the magnetic field sensor is mounted in the direct vicinity
of an AM radio antenna integrated into the rear window, it may
cause occasional interference in the radio reception in the long
wave range.
Notes on the operation of the system
In order to ensure the trouble-free operation of the navigation system, a
calibration must be performed after the equipment has been installed. A
special installation and calibration CD-ROM, including operating
instructions, is required. Software available for the Berlin RCM 303 A
operating panel from version 04.11.94 is capable of controlling the
navigation componentry. Older software must be replaced by the most
recent update, whereby an update for the tuner software is also required
(at least version 08.09.94).
Note: An error message list, a service checklist and diagnostic aids have
been included at the end of these installation instructions.
Componentry Fig. 1
The navigation componentry consists of a navigation computer with an
integrated CD-ROM drive (navigation unit), a NAVI interface, a GPS
receiver with an antenna, a precision resistor for the rear window
defogger, a magnetic field sensor, wheel sensors, a loudspeaker and
mounting material.
Mounting location for the navigation unit
Remove the transport block (two brass screws in the upper plate)
before beginning the installation work. Keep these screws in a safe
place in case the unit must be set in for servicing. After removing
the screws, insert the enclosed plugs into the holes in the upper
plate.
The navigation unit need not be installed at any particular position.
When choosing the mounting location for the navigation unit, you must
make sure that the unit is installed lying in a horizontal position (you must
be able to read the writing on the flap).
Make sure that there is enough room to insert the navigation CD into the
CD drive. Use the enclosed installation material in order to mount the
navigation unit.Positive connection Fig. 2
Positive connection Fig. 2
The navigation unit must be connected to permanent plus 12 V and
positive via the ignition.
Lay the permanent plus 12 V wire (red) to the battery (do not lay the wiring
directly by the wire harnesses). Attach the fuse carrier to protect the
positive wire and connect it to the positive terminal on the battery (if
necessary, drill a hole through the splashboard and use wire bushings
accordingly).
Connect the switching plus wire (black) with the fuse carrier at terminal
15 (switched to plus via the ignition) behind the fuse. In cars in which it
is not possible to connect the wire in the fuse box, use the enclosed fuse
carrier to connect the wire directly to terminal 15 at the ignition. Remove
the steering wheel panelling first.
Negative connection Fig. 2
Screw the negative wire (brown) directly onto the chassis. Scratch the
contact point for the ground down to the bare metal and grease it with
antiseize graphite petroleum (important for good grounding).
Testing the mounting location of the magnetic field
sensor
Two different tests are required.
1. Test for permanent magnetic interference
Load the installation disk.
Select „find compass location“, and then „compass ellipse“ and drive the
vehicle in a circle. A circle should appear on the display inside the
squares (ideally the circle should be in the centre). If this circle is partially
or entirely outside of the squares, then you must mount the magnetic field
sensor in a different place.
2. Testing for interference caused by other electrical equipment
Load the installation disk, select „find compass location“ and then
„compass error“.
Press „reset“, switch on the consumers (e.g. sliding sun roof, rear
window wiper).
The value indicated for „Loc. error“ must be less than 3.5.
Press reset each time you switch on a different piece of electrical
equipment.
After having tested each piece of electrical consumer individually,
check logical combinations as well. The sum of the values for the
consumers must not exceed a „Loc. error“ of 3.5.
If the value registered exceeds 3.5, then you must mount the
magnetic field sensor in a different location.
Note: Do not switch on the rear window defogger while testing for
interference from the electrical equipment. Any interference caused
by the rear window defogger is registered separately during
calibration and then compensated.
Precision resistor for the rear window defogger
(shunt)
The precision resistor has 2 connection wires and 1 measuring wire:
1. Connection to the ground contact of the rear window defogger
(length: 250 cm),
2. Connection to the vehicle chassis (length: 75 cm),
3. Measuring wire to the navigation unit (length: 50 cm), Fig. 3
The mounting location of the precision resistor depends on the length of
the wiring.
Do not lengthen the connection wires for the ground contact and the
vehicle chassis. Do not attach the connection for the vehicle chassis to
the liftback in estate wagons or liftback cars. Select the mounting location
for the precision resistor so that any heat build-up will be eliminated
(chassis metal).
Lay the measuring wire to the navigation unit and connect it to the
corresponding jack of the compact plug, Fig. 3
Note: No other electrical equipment (e.g. rear window wiper) may be
connected to the ground contact for the rear window defogger, except for
the rear window defogger.

Wheel sensors and magnetic strips Fig. 4
Safety instructions
Never screw the wheel sensor clamp onto any stress-bearing
parts.
Never drill holes in any stress-bearing parts.
Do not attach the sensor wiring to the brake lines or to any
moving parts.
The wheels must be tightened using the torque recommended
by the factory (approx. 100 Nm).
Mount the wheel sensors and the magnetic strips on the free-rolling
wheels, for four-wheel drive cars, on the rear wheels.
In order to mount both the wheel sensors and the magnetic strips, the
vehicle must be jacked up.
Screw the wheel sensors onto the sensor mounts and look for a suitable
mounting location. The sensors must not swing mechanically and they
should be placed in a sheltered location.
While mounting the wheel sensors, it is essential to comply with the
installation tolerances, Fig. 5
Mounting the magnetic strips
After you have found a suitable location for the wheel sensors, you must
determine the position of the magnetic strips on the inside of the wheel
rims. Mark the location selected for the magnetic strip and remove the
wheel.
Before unscrewing the wheel nuts, mark the position of the wheel on the
wheel hub.
Because the magnetic strips are glued into position, the rim must be free
of rust, dirt, grease and water. Clean the inside of the wheel rim
thoroughly (brake cleaning fluid, brake and clutch cleaner).
To ensure that the glue adheres properly, the rims must be at room
temperature.
After thoroughly cleaning and perhaps allowing the rims to warm up, glue
the magnetic strips onto the marked spots over the entire area parallel to
the outer edge of the rim, Fig. 4
Notes
Do not glue the magnetic strips directly onto the edge of the rim, as here
they can be damaged very easily.
Do not piece the magnetic strip together and cut it only at the
marked points (maximum gap between the beginning and end
point, one field = 25 mm).
Mount the wheels and tighten the nuts. Align the wheel sensors in
keeping with the installation tolerances, Fig. 5, and screw them on.
Lay the sensor wires into the interior of the vehicle (use any existing
bushings or drill new holes) and lay them to the navigation unit.
GPS receiver
Mounting the antenna
Important information:
- Mount the antenna on a metal roof only. It is not permissible to
mount the antenna on synthetic roofs or aluminium.
- When mounted on a roof (held only by a magnet), the antenna
must not be exposed to temperatures lying outside a range of -20°
C to +80° C.
- It is not permissible to mount the antenna on roofs covered with
leather or synthetic material.
- Use protective sheathing to protect the antenna wire from being
pinched.
- The adhering surface of the antenna must be free of dirt, snow, ice,
etc.
- You must not lengthen, shorten or bend the antenna wire. Do not
remove the plug during the installation.
- If the antenna is painted with the same colour as the vehicle,
especially paints containing a high percentage of metal, this may
adversely affect the reception. There is no guarantee that the
antenna will operate properly after it has been painted.
Seen from the driving direction, the antenna is to be mounted on the righthand side in the rear of the vehicle (passenger’s side, in Great Britain,
driver’s side). On notchback vehicles, mount the antenna on the lid of the
boot using the corner clamps, Fig. 6.
On estate wagons and liftback cars, set the antenna on the roof with its
magnetic foot, Fig. 7.
For a roof mount, remove the corner clamps, Fig. 8.
For estate wagons and liftback cars, lay the antenna wire along the rain
gutter downwards and into the interior of the vehicle, Fig. 9.
Any obstacles near the antenna, such as roof or bicycle carriers, may
adversely affect or even prevent satellite reception.
Lay the antenna wire into the interior of the vehicle and connect the BNC
plug on the antenna wire with the antenna jack on the GPS receiver.
It is advisable to remove the antenna from the roof when driving through
a carwash.
Installation of the GPS receiver
The mounting location of the GPS receiver depends on the length of the
antenna cable (2.5 m) and the connection line to the navigation unit (1.5
m).
Screw the GPS receiver into a dry position in the boot . Do not use screws
longer than 7 mm, otherwise you may destroy the GPS receiver, Fig. 10.
Loudspeaker
Install the loudspeaker for the voice directions in the foot area of the
vehicle so that it is possible to understand the voice instructions clearly.
Connecting the sensors for the navigation unit
Lay the connecting wires for the precision resistor, the wheel sensors, the
loudspeaker and the magnetic field sensor to the navigation unit and
connect them to the compact plugs, Fig. 11.
Display
The display is mounted on a swivel base.
If it is not possible to mount the display on a swivel base, you may
alternately use a gooseneck. You can order the gooseneck as an
accessory under the order number 7 607 039 100.
The hook-up wire can be laid into the base either from the side or from
underneath. In order to lay the wire into the base from underneath, drill
a 15 mm hole where the display is to be installed and pull the plug from
the display.
Warning: Make sure not to damage any other wires, the airbag, etc.
while drilling the hole.
In order to pull the plug in the display, screw it apart as follows:
1. Loosen the four screws on the back of the display and remove the
rear plate (Fig. 12).
2. Loosen the two screws on the strain relief inside and remove it
(Fig. 13).
3. Remove the plug carefully and push it through the base. Push the
wire through the hole where the display is to be installed, push it from
underneath into the base and plug it in. Screw the display back
together (Fig. 14).
The base can also be mounted on the back of the display. Proceed as
follows:
1. Loosen the four screws on the back plate of the display and remove
the rear plate (Fig. 12).
2. Loosen the two screws on the strain relief inside and remove it
(Fig. 13).
3. Remove the plug carefully and push it through the base.
4. Remove the cover from the back plate of the display and remove the
retaining spring (Fig. 15).
5. Pull the base off the back plate and insert it where the cover was
located (Fig. 16).
Push the retaining spring into the notch in the base, insert the cover
where the base was located, lay the wire through the base and reassemble the display (Fig. 17).
In order to mount the base, unscrew it and use four screws to fix it to the
installation location (Fig 18).
