    1.4.1.1. Activating the front camera input (dip 1) If set to ON, the interface switches for 10 seconds from the rear-view camera to the front camera input after having disengaged the reverse gear. In addition, a manual switch-over to the front camera input is possible via keypad (short press) from any image mode. Description of the front camera power supply: see chapter “Power supply output”.

    2.6. Connection – Video sources It is possible to connect an after-market rear-view camera, an after-market front camera and two more video sources to the video-interface. Before the final installation, we recommend a test-run to detect a incompatibility of vehicle and interface. Due to changes in the production of the vehicle manufacturer there’s always a possibility of incompatibility.

  • Page 14: Audio Insertion

    2.6.1. Audio insertion This interface is only able to insert video signals into the factory infotainment. If an AV- source is connected, the audio insertion has to be done by the factory audio AUX input or an FM-modulator. The inserted video-signal can be activated simultaneously to each audio- mode of the factory infotainment.

    2.6.3. After-market rear-view camera Some vehicles have a different reverse gear code on the CAN-bus which doesn’t communicate with the interface’s CAN. In this case there are two different ways of installation. If the interface’s CAN is able to detect an enabled vehicle’s reverse gear, the green wire of the 12pin cable should carry +12V while the reverse gear is engaged.

    2.6.3.2. Case 2: Interface does not receive the reverse gear signal If the video interface does not receive +12V on the green wire of the 12pin interface cable when reverse gear is engaged (not all vehicles are compatible), an external switching signal from the reverse gear light is required.
