Installation time

The installation time is approx. 2.75 hours, but may vary depending on the condition of the car and the equipment in it.

Important information

These installation instructions are primarily designed for use within the BMW dealership organization and by authorized BMW service companies.

In any event, the target group for these installation instructions is specialist personnel trained on BMW cars with the appropriate specialist knowledge.

All work must be completed using the latest BMW repair manuals, circuit diagrams, servicing manuals and work instructions, in a rational order, using the prescribed tools (special tools) and observing current health and safety regulations.

To avoid unnecessary extra work and/or costs, if any installation or function problem occurs, after a brief troubleshooting session (approx. 0.5 hours), please contact the following:

1. Either your national subsidiary or your regional office, or

2. The Support team via the Aftersales Assistance Portal (ASAP), using the optional technical parts support application.

Specify the chassis number and the part number of the installed retrofit kit and give a precise description of the problem.

Do not archive the hard copy of these installation instructions since daily updates are made by ASAP!

Installation information

Ensure that the cables/lines are not kinked or damaged as you install them in the car. Costs incurred as a result of this will not be reimbursed by BMW AG.

Additional cables/lines that you install must be secured with cable ties.

If the specified PIN chambers are occupied, bridges, double crimps or twin-lead terminals must be used.

Ordering instructions

The handle strip with rear-view camera B is not included in the retrofit kit and must be ordered separately (see EPC for part number and details).

5. To install the handle strip with rear-view camera

Mark the specific dimensions on the trunk lid (1) starting from the speed nuts (4) and the edge (3).

Drill through the trunk lid (1) at the drilling position (2) using a 12 mm twist drill bit.

Deburr the hole and coat the bare surfaces with preservative.

Unclip the handle strip (1) from the trim (2).

Do not damage the painted exterior of the trim (2).

Mark the specified dimensions on the trim (2) and saw out the marked area (1).

Clip the handle strip with rear-view camera B into the trim (1).

Push grommet Z onto the camera cable (2).

Not illustrated:

Route the camera cable (2) through the hole in the trunk lid.

Insert grommet Z into the hole in the trunk lid and fit the trim (1).

6. To install and connect the wiring harness

Connect the connection plug (2) of the rear-view camera and branch A1 (black 12-pin socket casing) to control unit C.

Affix protective strip D to control unit C. Cut off any excess lengths.

Use cable tie E to secure control unit C to the existing hole in the trunk lid (1).

Route wiring harness A to the right-hand side.

Cars built before 08/06 only

Connect branch A2, green cable, to the blue/ yellow cable from plug X328 (PIN 3) using miniature connector G.

Cars built after 08/06 only

Connect branch A2, green cable, to the blue/ yellow cable from plug X328 (PIN 4) using miniature connector G.

All cars

Route wiring harness A along the standard wiring harness through the grommet (1) into the righthand side of the trunk.

Route wiring harness A along the standard wiring harness to the left side of the trunk.

Remove the draw-in tool (1) from wiring harness A.

Insulate branch A3, GN cable, and branch A9, WS cable, and tie them back.

Connect branches A4 – A8 to branch K1 as follows:

  • Branch A4, transparent cable, to PIN 24
  • Branch A5, black/brown cable, to PIN 11
  • Branch A6, black cable, to PIN 23
  • Branch A7, red cable, to PIN 25
  • Branch A8, brown cable, to PIN 12

  • Branch J3, brown cable, to PIN 13

7. To install and connect the switchbox

Connect branches J1 and K1 to switchbox L.

Route branches K2 and K3, violet/white cables, to the navigation computer (1).

If the violet/white cable has a cross-section greater than 0.75 mm², use a twin-lead

terminal with the terminal parts V – Y.3

Cut the socket contact off branch K2 and connect it to the violet/white cable from plug X1312 (Bordeaux 18-pin socket casing, PIN 3) using miniature connector G.

Route branches J4 and J5 to the navigation computer (1).

Disconnect blue plug X1313 from the navigation computer (1).

Connect branch J4 to plug X1313

Connect branch J5 to the navigation computer (1)

Install the navigation computer (1).

Secure switchbox L to the standard wiring harness (1) using cable ties F.

8. Concluding work and coding

Affix information sticker AA under the on-board monitor (1).

This retrofit system does not require coding.

  • Connect the battery
  • Conduct a brief test

Check the function of the rear-view camera as follows:
