be used while standing or to display fixed menus or rear-view-camera video when the

vehicle is moving, for example the MP3 menu for DVD upgrades.

Changes/updates of the vehicle’s software can cause malfunctions of the interface. We

offer free software-updates for our interfaces for one year after purchase. To receive a free

update, the interface must be sent in at own cost. Labour cost for and other expenses

involved with the software-updates will not be refunded.

1. Prior to installation

Read the manual prior to installation.

Technical knowledge is necessary for installation. The place of installation has to be free of

Mercedes-Benz

Vito (W447) since about 2019

Garmin Audio30/Audio40

Only for head-units made by Garmin - not

compatbile with Audio40 made by Pioneer

Limitations

Video only The interface inserts ONLY video signals into the infotainment.

For inserting Audio signals either the possibly existing factory audio-AUX-input or

a FM-modulator can be used.

In case that 2 AV sources shall be connected, a desired audio switching will

require additional electronic.

Factory rear-view camera Automatically switching-back from inserted video to factory rear-view camera is

only possible while the reverse gear is engaged. To delay the switch-back an

additional electronic part is required.

After market front camera The front camera will automatically be switched for 10 seconds after disengaging

the reverse gear. A manually front camera switching is possible by external

keypad.

1.2. Checking the compatibility of vehicle and accessories

1.3. connectors - video-interface

The video-interface (daughter PCB) converts the video signals of connected after-market

sources in a factory monitor compatible picture signal which is inserted in the factory

monitor, by using separate trigger options.

1.5. Dip-switch settings

1.5.1. 8 dip - black

Some settings have to be selected by the dip-switches on the

video interface.

Dip position down is ON and position up is OFF.

*The front camera will automatically be switched for 10 seconds after disengaging the

reverse gear (see following information).

After each Dip-switch-change a power-reset of the Video Interface has to be performed!

1.5.1.1. 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”.

1.5.1.2. Enabling the interface’s video inputs (dip 2-3)

Only the enabled video inputs can be accessed when switching through the interface’s video

reverse gear is engaged.

Note: Dip 4, 6, 7 and 8 are out of function and have to be set to OFF.

After each Dip-switch-change a power-reset of the Video Interface has to be performed!

1.5.2. 4 dip - red

By using the Dip-switches, the factory Head-unit or vehicle can be chosen which the

interface will be connected to.

2. Installation

Switch off ignition and disconnect the vehicle’s battery! The interface needs a permanent

12V source. If according to factory rules disconnecting the battery is to be avoided, it is

usually sufficient to put the vehicle to “Sleep-Mode”. In case it does not succeed,

disconnect the battery with a resistor lead.

If power source is not taken directly from the battery, the connection has to be checked

for being start-up proven and permanent.

2.1. Place of installation

The video interface is designated to be connected behind the vehicle`s head unit.

The daughter PCB is prepared to be connected inside the factory head unit).

2.3. Installation –daughter PCB

Remove the factory monitor and open the head-unit`s housing. The daughter PCB is built to

be installed into the optical lead between the monitor panel and mainboard of the vehicles

monitor.
