1. Important notes

Installation time at least 2 hours, which can vary according to the condition and fittings of the vehicle.

Target group

The conversion work with installation kit for inside rear-view mirror with automatic anti-dazzle is to be carried out exclusively by a BMW specialist workshop. It is only here that the appropriately trained technical personnel who have the necessary tools and auxiliary materials are available.

Safety instructions

BMW accepts no liability for damage which occurs as a result of not following the work sequence and safety instructions. In addition, any warranty claim against BMW AG is extinguished in the event of improper fitting and handling whic h diverg es from the fitting and operating ins truc tions.

Electrical cables should be laid in such a way as to exclude any possibility of them being kinked, chafed or jammed.

Installation notes

Installation is shown on a left-hand drive model. For right-hand drive models, installation should be carried out in mirror image.

Tightening torques for screw fittings should be observed. For tightening torques required, please refer to the parts information system (TIS ).

Should specified pin terminals be assigned, bridges, double crimpings or parallel connections will have to be made.

On no account work with so-called ”Scotchlock quick connectors” as these can trigger faults in the on-board electronics.

2.3 Installation

Open fold-out page.
A


Install supplementary wiring harness (a) along the vehicle wiring harness as follows:
Branch cable A1-A3 to black, 10-contact connector (b) X18246 at interior rear-view mirror with automatic
anti-dazzle.
Branch cable A4 to ground post (1) X217 under the steering column.
Branch cable A5 to joint connector X428 in joint connector box (2) at fuse holder (3) X10016 in glove box.
Branch cable A6 to fuse holder (3) X10016 in glove box.
B


Guide branch cable A4-A6 between the A-pillar and the instrument panel (4) in the direction of the arrow.
C


Install the cable loom (5) of branch cables A4-A6 inside the recess (6) of the fresh air louvre over the body
plate (7) in the direction of the footwell.
Should cables have already been installed in this area, the cable loom (5) of branch cables A4-A6 should be
attached by a cable tie (j) (see parts overview) to the existing cable loom at the place where it passes over the
body plate (7) and goes into the footwell.
Cables should not interfere with the sphere of activity of the head airbag (8) inside the recess (6) of the fresh
air louvre.
D


To determine the precise attachment position of the cable holder (d) at the cable loom (9) of branch cables A1-A3,
measure the required laying length from the recess (10) via the A-pillar right up to the interior rear-view mirror on
the base plate.Then attach the cable holder (d) at the determined position with the aid of a piece of fabric adhesive
tape (not supplied in the parts kit) to the cable loom (9) of branch cables A1-A3 and press the cable holder (d) into
the recess (10).
In case cables have already been installed in this area, the cable loom (9) of branch cables A1-A3 should be
attached to the existing cable loom where it passes over the instrument panel (12) into the A-pillar using two cable
ties (j) (see parts overview).
Cables should not interfere with the sphere of activity of the head airbag (11) when they pass over from the
instrument panel (12) into the cable holders along the A-pillar.
E


Place cable loom (13) of branch cables A1-A3 in the cable holders (14) along the A-pillar.The cable holders (e and f)
included in the retrofit kit should be attached at the appropriate places to the cable loom (13) using fabric adhesive
tape (not included in the parts kit). Having pressed in the cable holders (e and f) the cable loom (13) should then be
attached at the notches provided for it.
In case cables have already been installed in this area, the cable loom (13) should be attached to the existing cable
loom with the aid of three cable ties (j) (see parts overview).
Cables should not interfere with the sphere of activity of the head airbag when they pass over from the A-pillar
into the roof body.
F


Pull the roof liner (15) down carefully and at the same time press the cable holders (g) provided in the cable set into
the notches designed for them.Then place the cable loom (16) of branch cables A1-A3 in the cable holders (g).
In case cables are already installed in this area, the cable loom (16) of branch cables A1-A3 should be placed in
the existing cable holders (g).
G


Guide the cable loom (17) of branch cables A1-A3 through the support (18) of the roof liner and then through the
recess (19). Guide cable loom (17) of branch cables A1-A3 through the rubber grommet (c).
In vehicles with rain sensor (manufacture date up to 9/98) there is a common cable covering instead of the
rubber grommet (c). In this case, the cable loom (17) of branch cables A1-A3 should be installed through the
common cable covering.
H


Vehicles without anti-theft alarm system:
Take the black, 10-contact connector (b) from the retrofit kit and separate it in order to be able to make the
connections of branch cables A1-A3 for the interior rear-view mirror with automatic anti-dazzle.

Vehicles with anti-theft alarm system:
In order to be able to make the following cable connections for the interior rear-view mirror with automatic
anti-dazzle, separate the existing black, 10-contact connector (b) and add, in addition to the connections
of the anti-theft alarm system, the branch cables A1-A3.
Vehicles with and without anti-theft alarm system:
Insert branch cables A1-A3 in the black, 10-contact connector (b) X18246 as follows:
Insert branch cable A1, cable colour green/white, in plug-in place 3.
Insert branch cable A2, cable colour brown/black, in plug-in place 10.
Insert branch cable A3, cable colour blue/yellow, in plug-in place 1.
Then reassemble the black, 10-contact connector (b).
I


The cable loom of branch cables A4-A6 should be attached to an existing cable loom in the area of the footwell
with the aid of four cable ties (j) (see parts overview).Then insert branch cable A4, cable colour brown black, at
ground post (20) X217 under the steering column at a non-assigned plug-in place.
If ground post (20) X217 is entirely assigned, use one of the two mini connectors (i) (2-way) supplied
in the parts kit.
J


Remove foam covering (21) at the centre console and install cable loom (22) of the branch cables A5-A6 through
the cable duct (23) in the centre console to the fuse holder X10016 on the front passenger side.
K


The cable loom of branch cables A5-A6 should be attached to an existing cable loom in the area of the fuse
holder with the aid of two cable ties (j) (see parts overview).
Undo joint connector box (24) at the support (25) of the fuse holder (26) and insert branch cable A5, cable colour
blue/yellow, in the same-colour joint connector X428.
If in the joint connector box (24) the joint connector X428 is entirely assigned, use one of the two mini
connectors (i) (2-way) supplied in the parts kit.
L


Insert branch cable A6, cable colour green/white, at fuse holder (27) X10016 Pin 48 plug-in place F24.
If the vehicle is not equipped with PDC (Park Distance Control), a flat-bladed fuse 5A (h) must be inserted
additionally at fuse holder (27), plug-in place F24.
Then put the black, 10-contact connector (b)on to the interior rear-view mirror with automatic anti-dazzle and
attach the interior rear-view mirror to the base plate at the windscreen.
Carry out function test.
Build back all dismantled units in the reverse order of disassembly
