Audio insertion
This interface can only insert video signals into the factory infotainment. If an AV source is
connected, the audio insertion has to be performed by a factory aux input or an 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, for audio switching an additional
electronic part is required.
2.4.3.
After-market rear-view camera
Some vehicles have a different reverse gear code on the CAN-bus which the video-interface
is not compatible with. Therefore, there are two different ways of installation. If the video
interface receives a signal of the reverse gear, the green wire
“Reverse-OUT”
of the 20pin
cable should carry +12V while the reverse gear is engaged.
Note:
Do not forget to set dip5 of the video-interface to
ON
before testing.
2.4.3.1.
Case 1: Video interface receives the reverse gear signal
If the CAN-bus interface re12V on the green wire of the 20pin cable when reverse
gear is engaged, it will automatically be switched to the rear-view camera input “Camera IN”
while reverse gear is engaged.
Connect the interface cable’s female 12pin connector to the interface’s 12pin
connector.
The 12 V power supply for the rear-view camera (max 3A) has to be taken from the
green wire of the 20pin cable to avoid an unnecessary, permanent power supply to
the camera electronic.
For the operation, both green cables
“Reverse IN”
and
“Reverse OUT”
have to remain
connected.
