Legal Information

By law, watching moving pictures while driving is prohibited, the driver must not be

distracted. We do not accept any liability for material damage or personal injury resulting,

directly or indirectly, from installation or operation of this product. Apart from using this

product in an unmoved vehicle, it should only be used 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. Up to

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

update, the interface has to be sent in at own cost. Wages for de-and reinstallation and

other expenditures 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 must be free of moisture and away from heat sources.

1.1. Delivery contents

Take down the serial number of the interface and store this manual for support

purposes: ____________________

Compatibility

Limitations

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

For audio inserting, use the possibly existing factory audio-AUX-

input or a FM-modulator. If 2 AV-sources shall be connected to the

infotainment, for audio switching an additional electronic part is

required.

Factory rear-view camera Automatic 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, 15 or 20

seconds (adjustable) after disengaging the reverse gear. A manually

front camera switching is possible by external keypad.

Video input signal NTSC video sources compatible only.

Mirror cameras If mirror cameras are connected, use only cameras which are

resistant to continuous current.

Guidelines and PDC Displayed guidelines and PDC are not available in all vehicles.

Guidelines can only be displayed together with PDC.

1.3. Warning notes:

Damage to the head-unit is possible, if this RL4-NAC12 interface is installed to older

Citroen / Peugeot SMEG or SMEG+ head-units (by Magneti Marelli)! Use this RL4-NAC12

interface only on Citroen/Opel/Peugeot/Toyota head-units NAC (by Continental) or RCC

(Bosch).

Designs and features –see the following pictures:

Furthermore, even when installed to the correct NAC systems, there is also damage to the

head-unit possible if the 4pin HSD connectors of this harness are wrong-plugged.

Prior to installation must be determined whether the head-unit of the vehicle is a

low version head-unit

(single black male 4pin

HSD on backside)

high version head-unit

(double black male 4pin

HSD on the backside)

Please, carefully follow the manual for high or low version connection of the head unit!

1.4. Connection - Video-Interface

The video-interface 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. Further it reads the vehicle’s digital signals out of the vehicle’s CAN-bus and

converts them for the video interface.

1.5. Settings of the 8 Dip switches (black)

Some settings have to be selected by the 8 dip-switches at the

video-interface. Dip position down is ON and position up is OFF.

See the following chapters for detailed information.

*The front camera will automatically be switched for 10, 15 or 20 seconds (adjustable) after

disengaging the reverse gear.

The camera power supply +12V will automatically be provided by the green wire "Reverse-Out"

when the reverse gear is engaged, plus 10, 15 or 20 seconds delay for the front camera, and

also +12V when the front camera is manually selected by external keypad (see chapter "Power

Supply Output").

**The display of the guidelines only works with simultaneous PDC display (Dip8 = ON).

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

1.5.1. Enabling the interface’s video inputs AV1-R and AV2-L (dip 1-2)

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

sources. It is recommended to enable only the required inputs. Then the disabled inputs will

be skipped while switching through the video interfaces inputs.

1.5.2. Activating –front camera back-switching V3 Front (dip 3)

If set to ON, the interface switches for 10, 15 or 20 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.

To power up the front cam, the video interfaces’ green wire „Reverse-Out“ will supply +12V

(max 3A) with engaging the reverse gear and additionally 10, 15 or 20 more seconds power

delay for the time of the front camera’s back-switching after the reverse gear has been

disengaged. Furthermore, the green wire’s power supply for the front cam becomes active

with manually front camera switching (short press of the external keypad).

1.5.3. Activation signal –video sources (dip 4)

For source activation via CAN, dip switch position ON must be selected.

For manual source activation via trigger wires, the switch position must be OFF.

1.5.4. Rear-view camera settings (dip 5)

If set to OFF, the interface switches to factory picture while the reverse gear is engaged to

display factory rear-view camera or factory optical park system picture.

If set to ON, the interface switches to its rear-view camera input while the reverse gear is

engaged.

1.5.5. Activating the guidelines (dip6)

If set to ON, the guide lines will be shown on the display.

If set to OFF, the guide lines won’t be visible on the display.

Note: The display of the guidelines only works with simultaneous PDC display (Dip8 = ON).

If there is no communication between interface and the vehicle`s CAN-bus (several vehicles

aren’t compatible), the reverse gear guide-lines can`t be shown during the vehicle’s

operation, even if they once appear after having switched the system to powerless!

1.5.6. Activating the factory PDC display (Dip-8)

Dip 8 is used to activate the factory PDC display (if available) when retrofitting an after-

market rear view camera. When dip switch is set to OFF, the factory PDC display is shown on

the right side of the display. With Dip switch position ON, the factory PDC display is not

shown.

Note: Dip 7 is out of function and has to be set to OFF.

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

1.6. Settings of the 4 Dip switches (CAN function - red)

In contrast to the 8-dip switches

dip position up = ON and position down = OFF!

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

2. Installation

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

permanent 12V source. If -according to factory rules- a disconnection of the battery has to

be avoided, it should be sufficient to use the vehicle’s sleep-mode. In case, the sleep-mode

doesn’t succeed, the battery has to be disconnected with a resistor lead.

The Interface needs a permanent power supply! If power isn’t directly taken from the

battery, the connection’s power has to be checked for being start-up proven and

permanent.

Before the final installation, we recommend a test-run of the interface. Due to changes in

the production of the vehicle manufacturer, there’s always the possibility of

incompatibility.

2.1. Place of installation –video-interface

The video-interface is performed to be installed at the head unit’s rear side.
