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 seconds after
disengaging the reverse gear. A manually front camera switching is
possible by external keypad.
Video input signal NTSC video sources compatible only.
NAC high-version If the two HSD connectors cannot be separated for the reconnection of
the white HSD socket, the separately available cable CAB-HSD-MF026 can
optionally be connected here.
Guidelines and PDC Displayed guidelines and the optical PDC are not available in all vehicles.

1.3. Warning notes:
Damage to the head-unit is possible, if this RL4-NAC08 interface is installed to older
Citroen / Peugeot SMEG or SMEG+ head-units (by Magneti Marelli)! Use this RL4-NAC08
interface only on Citroen/Opel/Peugeot/Toyota head-units NAC (by Continental) or RCC
(Bosch). Designs and features –see the following pictures:
NAC-Systems
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
-the 4pin HSD harness is connected to the vehicle monitor
Prior to installation, the head-unit’s version has to be determined (see following page).

Version 13.07.2023 HW: CAM(V100)/(V52) RL4-NAC08
Page7
1.4. Checking the head unit’s version
Prior to installation, it has to be determined if whether the head-units version is a
low version head-unit
(single black male 4pin
HSD on backside)
Attention: Bosch Low Version requires different
Dip 8 switch position (see following chapters)
OR
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.
The monitor resolution (dip 8) is independent of the version of the head-unit. A low-
version head-unit can also have the high resolution.

Version 13.07.2023 HW: CAM(V100)/(V52) RL4-NAC08
Page8
1.5. Connectors - 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.
1.6. 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.
*The front camera will automatically be switched for 10 seconds after disengaging the
reverse gear.
See the following chapters for detailed information.

1.6.1. Adjustment –power supply output (dip 1)
If set to ON, the video interfaces’ red wire will supply +12V (max 3A) with engaging the
reverse gear and additionally 10 more seconds delay for the time of the front camera’s back-
switching after the reverse gear has been disengaged. Furthermore, the red wire’s power
supply for the front cam becomes active with manually front camera switching (short press
of the external keypad).
If set to OFF, the video interfaces’ red wire will supply permanent +12V ACC (max 3A).
Description of the power supply output: see chapter “Power supply output”.
1.6.2. Enabling the interface’s video inputs (dip 2-3)
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.
1.6.3. 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.
1.6.4. Activating –front camera back-switching (dip 6)
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.
(Attend to correct adjustment of the power supply output (dip1)!
1.6.5. Head unit selection (Dip 8)
Dipswitch 8 is used to set the corresponding resolution of the factory monitor.
Dip switch position ON supports the low resolution monitor.
Dip switch position OFF supports the high resolution monitor.
Note: If you do not know the resolution, test both settings.
Note: Dip4 and 7 are out of function and have to be set to OFF.
After each Dip-switch-change a power-reset of the interface box has to be performed!

2. Installation
To install the interface, first switch off the ignition and disconnect the vehicle’s battery.
Please read the owner`s manual of the car, regarding the battery`s disconnection! If
required, enable the car`s Sleep-mode (hibernation mode)
In case the sleep-mode does not succeed, the disconnection of the battery can be done
with a resistor lead.
As with any installation of retrofit equipment, a stand-by test is neccessary after the
installation of the video interface, to ensure that the unit also switches off after reaching
the vehicle‘s sleep mode.
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.
Erfahrungswerte zu Einbauorten:
Radio/Navi in Peugeot 2008 FY 2019 vehicles: Directly behind the display.
Head Units in Peugeot 5008 and Opel Grandland X vehicles: Behind the centre console (for
this, remove the panel in the passenger footwell).

Disconnect the vehicle harness’ female double 4pin HSD
connector at the head unit’s rearside, separate
the white 4pin HSD connector from the
black one and again connect the single
white 4pin HSD connector to the
head-unit’s same male 4pin HSD
connector, where it has been connected before.
Special case: If the two HSD connectors cannot be separated
for the reconnection of the white HSD socket, the cable
CAB-HSD-MF100 or CAB-HSD-MF026 can optionally be connected here.
Connect the female black single 4pin HSD connector to the waterblue coloured
male 4pin HSD connector of the 4pin HSD harness.
Connect the opposite waterblue coloured female 4pin HSD connector of the 4pin HSD
harness to the previously become free male 4pin HSD connector of the head-unit.
Attention: The picture’s representation of the double 4-pin HSD connector may be reversed.
Make sure that the white 4pin HSD connector is reconnected to the same position of the
head unit, where it has been connected before!
