Location 

The reversing camera forms a single component with the reversing camera (RFK) control unit (B84/3) (model 447.6/7, 448.7 with code W65 (Liftgate)) or the reversing camera (RFK) control unit (B84/5) (model 447.8, 448.8) or the rear-end door reversing camera (RFK) control unit (B84/10) (model 447.6/7, 448.7 with code W50 (Two-wing rear-end door, 180 degrees without window) or with code W54 (Two-wing rear-end door, 270 degrees)), and it is located in the handle strip of the liftgate or in the license plate molding of the left rear-end door.

Task 

The backup camera does the following:

Recording of the area to the rear of the vehicle 

The reversing camera is an optical parking aid. Its tasks include the recording of images of the area to the rear of the vehicle, the generation of dynamic guide lines and transmission of picture signals to the radio (Audio) (N87/2) (model 447.6/7, 448.7) or the radio (Audio/COMAND) (N87/6) (MODEL 447.8, 448.8). The recorded pictures are processed and electronically corrected.

Reading in of signals 

The following information is also read in over the front end CAN (CAN G) (model 447.6/7, 448.7) or over the user interface CAN (CAN HMI) (model 447.8, 448.8):

The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).

Evaluation of input factors 

The input factors that have been read in are evaluated and corresponding signals are issued.

Output of signals 

The signals are issued through the following connections:

Low voltage differential signal (LVDS) line 

The picture signals are sent over the low voltage differential signal (LVDS) line to the radio (audio) (N87/2) (model 447.6/7, 448.7) or the radio (Audio/COMAND) (N87/6) (model 447.8, 448.8).

Front end CAN (CAN G) (model 447.6/7, 448.7) 

The following signals also read out issued via front end CAN (CAN G):

The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).

User interface CAN (CAN HMI) (model 447.8, 448.8) 

The following signals also read out issued via user interface CAN (CAN HMI):

The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).

Body 

The backup camera is a color image camera with wide-angle lens.
