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.
If you experience installation or function problems, restrict troubleshooting to approx. 0.5 hours for mechanical work and 1.0 hour for electrical work.
In order to reduce costs and avoid any additional expense, send a query immediately to the Technical Parts Support via the Aftersales Assistance Portal (ASAP).
Specify the following information:
– Chassis number
– Part number of the retrofit kit
– A precise description of the problem
– Work steps already carried out

Installation information
Due to the large number of bumper trims, the installation of the Side View cannot be shown in detail for every equipment variant. The installation work is to be carried out in the same way.
Ensure that the cables and/or 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.
All pictures show LHD cars; proceed accordingly on RHD cars.
In most cases, after installation of the retrofit, repairs or a software update of the car, an image
misalignment appears on the Control Display. To correct the image misalignment, the ACM Unit must be initialised.
The initialisation is to be carried out as detailed in the ACM installation instructions 01 29 0 420 167.
Ordering instructions
The rear view Y is not included in the Round Vision retrofit kit with 2 cameras and must be ordered separately (see EPC for part number and further details).

5.Installing and connecting Side View
Secure side view P to the holder Q using Philips screws S.
Side View P must not project beyond the outline of the car (1), otherwise the homologation for the car will be invalid.
Guide the camera cable (3) through the upper central section of the grille (4), if necessary sawing out one bar of the grille (4).
Position side view P in the centre on the underside of the bumper trim (1).
Mark the positions of the holes (2).
Drill through the bumper trim (1) with a 5.5 mm twist drill.
Use hexagonal screws U and hexagonal nuts T to secure side view P on the bumper trim (1).
Align Side View P horizontally to the cars axis by carefully bending the holder.
To prevent picture problems, do not connect and secure branch O1 (WS 4-pin socket casing) in the immediate vicinity of the headlight.
Route the camera cable behind the left headlight.
Connect the plug (1) on the camera cable to branch O1.
Install the bumper trim.
Route the Side View cable harness O to the brake servo unit.
To avoid damaging the reverse brake booster, carefully drill through grommet (1).
Drill through the grommet (1) in the marked area (2) using a 15mm step drill bit.
Route side view wiring harness O through the grommet (1)into the footwell.
Route side view cable kit O along the standard wiring harness to branch (1), black 18-pin socket casing, from retrofit cable ACM.
Connect branches O2–O5 as follows to socket
casing AA (black 18-pin).
– Branch )2, black cable, to PIN 7
– Branch O3, white cable, to PIN 16
– Branch O4, brown cable, to PIN 1
– Branch O5, red cable, to PIN 10
Keep pin casing (1) of the ACM retrofit cable, black 18-pin for further connection.
6.Installing and connecting rear view
Plug casing Z (green 2-pin) is attached to the connection cable of the button (3).
Disconnect the cable (2) of the button (3) from the existing plug (1) and connect to plug casing Z.
Connect plug casing Z on socket casing X13107 (2-pin SW) of the boot lid (1).
Route the connection plug (2) of the rear view into the tailgate (1) to the wiper motor.
Clip rear view Y into the tailgate (1).
Connect the connection plug (2) of the rear view on branch X1 (black 4-pin plug casing).
Route rear view wiring harness X along the standard wiring harness on the right-hand side of the boot lid (1).
Route rear view wiring harness X along the standard wiring harness through the grommet (1) into the bootspace.
Route rear view cable kit X along the standard wiring harness to branch (1), black 18-pin socket casing, from retrofit cable ACM.
