Audio insertion
This interface can only insert video signals into the factory infotainment. Audio insertion
must be done by factory audio AUX input, the optionally available AUX-in interface AUX-110
(only for MMI3G, not for MMI3G+) or FM-modulator. The inserted video-signal can be
activated simultaneously to each audio-mode of the factory infotainment.
If 2 AV sources shall be connected to the infotainment, additional electronic is necessary to
switch the audio signals.
2.8.2.
After-market rear-view camera
Some vehicles have a different reverse gear code on the CAN-bus which the included CAN-
box is not compatible with. Therefore, there are two different ways of installation. If the
CAN-box detectes the vehicle’s reverse gear, the green wire of the 6pin to 8pin cable should
carry +12V while the reverse gear is engaged.
Note: Do not forget to set dip5 of video-interface to ON before testing.
2.8.2.1.
Case 1: CAN-box detects reverse gear
If the CAN-bus interface de12V on the green wire of the 6pin to 8pin cable when
reverse gear is engaged, the video interface will automatically be switched to the rear-view
camera input CAM while reverse gear is engaged.
Additionally, the +12V (max. 500mA) power supply for the rear-view camera can be
taken from the green wire of the 6pin to 8pin cable.
