GNote the safety instructions of the vehicle manufacturer (airbags, immobilisers etc.).
• When routing the cables, ensure that they cannot become jammed, kinked or ripped out.
• Before installation, park the vehicle in a safe and level place and remove the ignition key.
• If using branch connections, it is important to note the relevant cable section.

GPeople with pacemakers should avoid physical contact with the magnetic antenna and should not carry the antenna
on their person, as this may affect the function of the pacemaker.
Keep the magnetic antenna away from data storage media (disks, credit cards, magnetic cards etc.) and electronic and
precision engineering equipment, as this may cause data to be deleted.
Do not use the antenna in areas at risk of explosion.
It is important to secure the antenna so that it cannot become detached in a collision or sudden brake manoeuvre.

a. Attach the antenna to a flat, pre-washed metal surface.
b. Then guide the antenna cable into the vehicle interior.
GThe maximum vehicle speed for the antenna if magnetically attached is 180 km/h. The antenna must be removed or
specially secured at higher speeds.
The antenna is not suitable for car-wash facilities.

)The antenna can only be installed on a non-metallised windscreen.
)When selecting the installation position, ensure that the antenna has a clear view of all directions, and that it
is not covered by the windscreen wipers. Obstructions caused by the bonnet, window crossbeams and roof
should be avoided as far as possible.

a. Secure the antenna to the base plate (1) with magnets.
b. Remove protective strip from top of adhesive tape (2) and stick to the centre of the base plate underside.
c. Remove protective strip from bottom of adhesive tape (2) and stick the antenna and base plate onto the vehicle
console beneath the windscreen at the installation position.
)GPS reception can be affected by screens with screen antenna, windscreen heating or thermally insulated
screens. Some thermally insulated screens are coated with titanium or silver oxide. Installation of the GPS
antenna in the vehicle interior can considerably impair the function of the navigation system.

signal is usually connected to the DIN - ISO plug of the car
radio. The assignment of the DIN - ISO plug may vary de-
pending on the vehicle type.

A speed sensor which generates a digital, speed-dependent signal must
be installed in the speedometer cable.
The VDO adapter 2152.30300000 or a vehicle-specific adapter which
satisfies the minimum requirements can be used. The VDO speed sen-
sor is suitable for direct installation on the gearbox (no further installa-
tion parts required) or in the speedometer cable (in conjunction with
additional universal installation parts).
)If the sealed speedometer cable is released, a correct dis-
play cannot be guaranteed. Incorrect installation leads to
improper functioning of the navigation system or of the
speedometer.

In order to install the speed sensor, the speedometer drive cable must be
cut in one even piece for insertion of the speed sensor. When removing
the speedometer cable from the vehicle, ensure that the location of the
evenly running piece is established and marked accordingly.
Installation is illustrated without reference to any specific vehicle. In
addition to the sensor, the following VDO universal parts are required:
1 x connecting piece 1040 1300 025 (VDO part number)
2 x knurled nuts1 040 1000 003 (VDO part number)
2 x hose sleeves 1040 1000 031 (VDO part number)
2 x dogs 1 040 1000 049 (VDO part number)
2 x friction washers 1040 0900 003 300 (VDO part number)
2 x fuel washers 4.0 KN07.0570.18 (VDO part number)
2 x washers KN11.1904.122 (VDO part number)
An appropriate, complete kit from VDO (part number X 39397106191)
can also be used.

Recommended tool: Cable installation tool for speedometer cables
from VDO, order number: 1999.10.13.000.110
If you require vehicle-specific parts, please consult the vehicle manu-
facturer or your nearest VDO branch.
• Using a metal saw, saw into the cable approx. 1 mm at right angles
to the profile and break off (Figure 3).
• Then cut the cable in the centre with side-cutting pliers
(Figure 4).
)For protective hoses with wire netting, the hose and flex ca-
ble can be cut directly with the side-cutting pliers.
• Shorten the protective hose again at both ends up to the plastic
sheathing. Check whether the ends of the flex cable still engage in
the speedometer and the gearbox.
• Shorten the inner cable to a projection of 13 mm (Figure 5).
• Connect the union nut and hose sleeve (Figure 6) and push onto the
hose ends (Figure 7).
• Connect friction washer to dog (Figure 8).
• Remove grease from flex cable and connect dog to flex cable. Us-
ing a suitable installation tool, press the dog onto the flex cable
(Figure 9).

)When pressing in, ensure that the dog is securely positioned
and that it runs smoothly.
• Pull the hose sleeve and nut as far as possible in the direction of the
dog, to achieve approx. 1-2 mm play (Figure 10).
Slightly squeeze the hose sleeve with pliers. Wrap with isolating
tape to secure (Figure 11).
• Screw the connecting piece and the speed sensor into the cable
(Figure 12).
• Connect speed sensor using the extension cable from VDO (part
number: 2152.90 30 0100).
