Checking the compatibility of vehicle and accessories

Compatibility

Limitations

C AN-bus compatibility|

• CAN-bus compatibility of interface may to some vehicles have no or
• limited compatibility. This can show on installation as well as later. Interface and all its video-inputs can be operated with analogue trigger signals, without connection to vehicle CAN-bus.
• Yet, in this case, some features do not work, see chapter 2.4.2 Analogue connection without CAN-bus.

---|---
Video only| Interface inserts only video-signal s into the infotainment. To insert audio signals a possibly existing factory audio-AUX-input or other optional products (e.g. AUX-UNI0x, FM-Modulator) must be used. Only for Comand Online NTG5-205, the optional OBD-coder for factory audio-AUX is available (OBD-N5-X-01).
Factory rear-view camera| Automatic switching to factory rear-view camera input is only possible while reverse gear is engaged. For deviating switching times optional accessories are required.
After market front camera| Front camera will automatically be switched to for 5, 10, 15 or 20 seconds (depending on menu setting) after disengaging the reverse gear. Manual switching to front camera is possible by external keypad.
Driving-path lines and PDC| It is possible that the vehicle CAN-bus is not fully compatible to the interface. In this case driving-path lines and optical PDC display will not be supported.

Boxes and connectors – interface
The interface converts connected after-market sources’ video-signals into a video-signal compatible with the factory monitor. It can then be inserted, using separate trigger options. The interface also reads the vehicle’s CAN-bus signals and uses them for own functions.

Settings – 8dip switch bench (interface functions)
Interface box, right side, black
Dip position UP = OFF and DOWN = ON.

• The front camera will automatically be switched for 5, 10, 15 or 20 seconds after disengaging reverse gear (depending on OSD-menu setting).
• On RL4-MBN51-A, dip 5 and dip 6 have no function. Set both OFF.

See following chapters for detailed information about 8dip switch bench.

1. Video inputs V1-Left and V2-Right (dip 1-2)
   With dip 1 (dip 2) = ON, the CVBS/AHD input V1-Left (V2-Right) for side-camera or other video-sources is enabled. Only enabled video inputs can be accessed – no matter whether automatically or manually switched. We recommend to enable only used inputs to avoid unwanted switching.

2. Front camera input V3-Front (dip 3)
   With dip 3 = ON the interface switches to its CVBS/AHD front camera input V3-Front after disengagement of reverse gear. Additionally, manual switching to front camera input is possible by the external keypad (short press) from any video mode.
   In the OSD-menu settings it is possible to set the automatic front camera display time from 5, 10; 15 or 20 seconds or shut it off. Therefore, it is also possible to connect a video-source other than from camera.

3. Rear-view camera settings (dip 4)
   With dip 4 = OFF, the interface switches to factory picture while reverse gear is engaged, to display factory rear-view camera or factory optical park system picture.
   With dip 4 = ON, while the reverse gear is engaged the interface switches to its CVBS/AHD rear-view camera input V4-Reverse (provided that dip 5 is set to OFF) or to its HDMI-input*
   (provided dip 5 and dip 6 are set to ON).
   Note: V4-Reverse remains without function with HDMI rear-view camera (dip 5 = ON).

4. Rear-view cam connection type (dip 5)
   With dip 5 = ON, the HDMI-input will be used as rear-view camera input. Additionally, the HDMI-input must be enabled with dip 6 = ON.
   With dip 5 = OFF, the V4-Reverse input is used as rear-view camera input.
   Note: Automatic switching to front camera for the pre-set time, after disengaging reverse, is working in both cases.

5. HDMI-input (dip 6)
   With dip 6 = ON, the HDMI-input is enabled and can be used for various HDMI- sources (e.g., rear-view camera or 360° camera-system, smartphone, laptop, streaming stick, DVB-T2 tuner, etc.). For rear-view camera or 360° camera system, additionally set dip 5 = ON.
   With dip 6 = OFF, the HDMI-input* is disabled.

6.  Driving-path lines (dip 7)
   With dip 7 = ON, the driving-path lines are enabled and shown on the display.
   With dip 7 = OFF, the driving-path lines are disabled and not shown on the display.
   Note: On vehicles, where driving-path lines due to lack of CAN-bus compatibility are not shown or are subject to post installation problems, the function cannot be used. In this case set dip 7 = OFF.

7.  PDC Graphic (dip 8)
   With dip 8 = ON, the interface PDC-graphic will be enabled and shown picture- in-picture in combination with the rear-view camera image.
   With dip 8 = OFF, the rear-view camera image is shown full-screen, without PDC-graphic.
   Note: On vehicles, where the PDC-graphic due to lack of CAN-bus compatibility cannot be used or is subject to post installation problems, the function cannot be used. In this case set dip 8 = OFF.

Installation

• For installation, first switch off the ignition and disconnect the vehicle’s battery following the instructions of the vehicle manufacturer regarding battery disconnection! If disconnecting battery is not suggested, enable vehicle sleep-mode (hibernation mode).
• In case the sleep-mode does not succeed, the disconnection of battery can be done with a resistor lead.

Before final installation, a test-run of interface and all connected devices is recommended to ensure compatibility of the complete installation. Due to at any time possible changes  in the vehicle manufacturers’ productions, incompatibilities can never be ruled out.
As on any installation of retrofit equipment, a stand-by test is necessary after installation to ensure that the retrofit products switch off after the vehicle enters sleep mode.

1. Place of connection
   The video-interface has to be connected at the head-unit’s rear side.
   Attention! Do not connect to vehicle monitor damage to hardware!

2. Connection schema

3. Connection – picture signal cable
   Remove head-unit.

1. Connect waterblue female HSD+2 connector to waterblue male HSD+2 connector of interface.
2. Disconnect single blue female HSD connector of factory harness from rearside of head-unit and connect it to bordeaux male HSD connector of picture signal cable.
3. Connect waterblue female 4pin HSD connector to blue male HSD connector at rear-side of head-unit.
   Note: If the factory HSD picture signal cable of the vehicle harness is too short for the installation, an HSD extension cable can be ordered separately with item number CAB-HSD-ML100.

Connection – harnesses, power supply and CAN-bus or analogue without CAN- bus

• The interface can be integrated via CAN-bus as well as operated in analogue mode without CAN-bus connection.
• When integrated via CAN-bus, the interface is switched on by the vehicle CAN-bus and R-gear signal and turn signals are usually recognized. In some vehicles also driving-path lines and optical PDC can be displayed, using CAN-bus steering signals and parking sensor data.
• Exceptionally, the CAN-communication is not (fully) compatible. If after connection of 10pin power/CAN cable with ignition on, no interface LED is on, the analogue connection described hereinafter must be made. Also, to avoid possible afterwards CAN-bus incompatibility, an analogue connection is also possible. Thereby the interface must be switched on  as well as switched over to its inputs by +12V switch inputs.
• With analogue connection, driving-path lines and PDC cannot be displayed.
• No matter whether connection is done with CAN-bus or analogue without CAN-bus, black GND wire and yellow +12V ACC/S-contact wire of 10pin power/CAN cable must be connected.

1. Connect female 10pin connector of 10pin power/CAN cable to male 10pin connector of interface.
2. Connect female 20pin connector of 20pin interface cable to male 20pin connector of interface.
3. Connect black GND wire of 10pin power/CAN cable to stabile vehicle’s negative ground.
4. Connect yellow +12V ACC/S-contact wire of 10pin power/CAN cable to +12V ACC (terminal 15r) or S-contact (terminal 86s) of vehicle.

Connection with CAN-bus

1. Remove the female Quadlock connector of the vehicle harness from the rear-side of the head-unit and connect the previously clipped out black female 12pin connector (see graphic) to the male 12pin connector of the PNP harness.
2. Clip in the female 12pin connector of the PNP harness in the previously become free position of the female Quadlock connector before finishing the Quadlock reconnection at the rear-side of the head-unit.

Attention! If connecting to CAN-bus in combination with yellow wire to +12V BATT (terminal 30), it could happen generally or sporadically, especially but not only on Opel vehicles, that the interface does not shut off in sleep mode. Therefore, connecting the vellow wire to +12V BATT is at own risk.
Analogue connection without CAN-bus
With analogue connection, the four CAN wires of the 10pin power/CAN cable are not connected – for this, the four wires of the 10pin power/CAN cable must be disconnected!

1. Disconnect and isolate the 4 CAN bus wires (grey, blue, white and green) of the 20pin interface cable about 4-5 cm behind the black connector.
2. Connect purple wire Manual ACC of 20pin interface cable to +12V S-contact terminal 86s or ACC terminal 15r of vehicle (e.g., cigarette lighter, glove compartment illumination).

Notes

• Only as long as the interface is switched on via +12V on Manual ACC, the monitor can show picture. Otherwise, also the factory picture is black.
• When selecting the switch-on signal, please check whether the factory picture is available in all desired operating states.
• With analogue connection, driving-path lines and PDC cannot be displayed.
• With analogue connection of interface (without CAN-bus), the connection of rear-view camera and side-cameras must also be made analogue.

See chapters :

• Case 2: Reverse signal analogue connection
• Case 2: Turn signal analogue connection

Power supply outputs

• The two red and green power supply cables ACC out 12V (max 3A) and CAM power 12V (max 3A) of the 20-pin interface cable can be used either as ACC power supply for external video-sources connected to the inputs V1-Left, V2-Right, V3-Front or HDMI-input (e.g., iOS/Android devices, laptop, streaming stick, DVB-T2 tuner), or as power supply for the after-market cameras connected  to the V1-Left, V2-Right, V3-Front, V4-Reverse or HDMI-input (e.g., rear-view, front and side-cameras).

1. External video-sources (no cameras) can be supplied with power via the red power supply cable ACC out 12V (max 3A) of the 20pin interface cable. The cable carries +12V ACC trigger out power permanently while interface is powered (see following chapters for connection).

2. The power supply for after-market cameras (e.g., rear-view, side and/or front camera) can be supplied by the green power supply cable CAM power 12V (max 3A) of the 20pin interface cable. The cable carries +12V trigger out power exclusively as long as any of the camera inputs is shown, regardless of whether the switching is by vehicle CAN-bus or by trigger wires (see following chapters for connection).

5. Connect power supply for other video-sources to red cable ACC out +12V (max 3A) of 20pin interface cable.

Note : The type of camera switching (by CAN-bus or trigger cables) can be preset in the OSD-menu settings individually for each input.

After-market rear-view camera
Automatic switching to rear-view camera is possible by CAN-bus or by analogue reverse signal.

1. Case 1: Reverse signal by CAN-bus
   • Basic requirement is that the interface is connected to CAN-bus. Furthermore, vehicle CAN-bus reverse signal and its detection by the interface must be compatible.
   • If so, interface supplies +12V on green wire CAM power 12V (max 3A) of 20pin interface cable while reverse gear is engaged and interface automatically switches to rear-view camera input V4-Reverse or HDMI-input*.
   • See also chapter 1.5 Settings – 8dip switch bench (interface functions).

The +12V (max. 3A) power supply for the rear-view camera can be taken from the green wire CAM power 12V (max 3A) of the 20pin interface cable, as it carries voltage only for the time of camera input activation (some cameras are not continuously current-stable).
Notes

• If HDMI-input* is defined as rear-view camera input by dip 5, V4-Reverse input remains without function!
• If reverse gear detection of interface by CAN-bus does not work, reverse gear signal has to be connected analogue.

Case 2: Reverse signal analogue connection
If interface does not deliver +12V on green wire CAM power 12V (max 3A) of 20pin interface cable when reverse gear is engaged (not all vehicles are compatible), an external switching signal from reverse gear light is required. As the power supply of reverse gear light is not voltage-stabile all the time, a normally open relay (e.g., AC-MR-312 or AC-MR-201) or filter (e.g., AC-PNF- RVC) is required. The diagram below shows the connection with relay.

1. Connect green wire Trig-Rear to output connector (87) of relay.
2. Connect the power cable of vehicle reverse light to relay coil (85) and vehicle ground to relay coil (86).
3. Connect output connector (87) of relay to power cable of rear-view camera, additionally to green wire Trig-Rear.
4. Connect stabile and permanent +12V to input connector (30) of relay.
   HDMI-input only available on HDV-MBN51

After-market front camera

1. The green wire CAM power 12V (max 3A) can be used to supply power to front camera (and all other cameras connected to the video inputs), as it only carries current for the duration of any camera activation (some cameras are not continuously current-stable). Requirement is
   dip 3 = ON (black 8dip switch bench). Then green wire carries +12V (max 3A) as power supply for the front camera as long as the front camera input is displayed.
   The time of display delay can be selected individually for 5, 10, 15 or 20 seconds in the front camera OSD-menu settings.
   Switching to front camera after disengaging reverse gear for the time set in the OSD-menu, takes place both, with connection by vehicle CAN-bus and with analogue connection of the rear camera.
   Note: In addition, manual switching to front camera input (short press) is possible by external button from any image mode (see chapter 3 Interface operation).

After-market side-cameras
Side-cameras can be connected with switching by CAN-bus or analogue.

1. Case 1: Turn signal from CAN-bus
   Basic requirement is that the connection is made with CAN-bus. Furthermore, vehicle CAN-bus reverse signal and its detection must be compatible with the interface.
   If so, interface supplies +12V on green wire CAM power 12V (max 3A) of 20pin interface cable for the duration of turn signal operations.

1. Power supply for side-cameras should be connected to green wire CAM power 12V (max 3A) of 20pin interface cable, as this cable is only powered during camera activation (some cameras are not continuously current stable).
   Note: If turn signal detection of interface is not compatible with the vehicle CAN-bus, the turn signals must be connected analogue.

2. Case 2: Turn signal analogue connection
   With analogue connection, e.g., because signals from the vehicle CAN-bus are not recognised, the analogue switching is possible the two +12V trigger input wires Trig-Left and Trig-Right. For switching to the side-camera inputs, an external switching signal from the turn signal bulb is required. Since the turn signal may contain electronic interference, for each input, a normally open relay (e.g., AC-RW-1230 with wiring AC-RS5) or a noise filter (e.g., AC- PNF-RVC) is required. The diagram below shows the connection of a normally open relay.

1. Connect light blue wire Trig-Left to output connector (87) of relay.
2. Connect power-cable of left turn signal to coil (85) of relay and coil (86) of relay to vehicle ground.
3. Connect output connector (87) of relay to power cable of rear-view camera, additionally to light blue wire Trig-Left.
4. Connect stabile and permanent +12V to input connector (30) of relay.
5. Same connection applies to right side-camera just the dark blue wire Trig-Right.

HDMI rear-view camera or other HDMI-source (only HDV-MBN51)
The HDMI-input* of the interface can generally be used for any video-source with HDMI-output, connected to it, e.g., rear-view camera, 360° camera-system or other video-source such as smartphones, laptop, streaming stick, DVB-T2 tuner, etc.

1. If an optional HDMI video-source (e.g., smartphone, laptop, etc.) is connected to the
   HDMI-input, the video shown on the display of the HDMI-source will be mirrored on the vehicle monitor. The video-signal from display-free sources (e.g., streaming stick, DVD-Player, DVB-T2 Tuner, etc.) will be displayed on the vehicle monitor. The power supply for the video-source can be taken from red wire ACC out 12V (max 3A).
   Received audio signals will only be supplied by the female 3.5 mm jack connector
   HDMI-Audio out of the 20pin interface cable. See following chapter 2.10 Audio-insertion.

2. If a rear-view camera or 360° camera-system is connected to the HDMI-input* (switched to by CAN-bus or analogue), the image displayed while reverse gear is engaged, and the image of a front camera connected to V3-Front is also displayed for the preset time when reverse gear is disengaged. Power supply can be taken from green wire CAM power 12V (max3A).
   HDMI-input only available on HDV-MBN51

Audio-insertion

• The interface can only insert video-signals into the factory infotainment.
  Audio signals of the HDMI-input are supplied through the 3.5 mm female jack connector HDMI-Audio out of the interface. For all AV-sources connected to the interface, their audio output must be connected factory AUX input or an optional audio-inserter (e.g., AUX-UNI0x, FM modulator. If several AV-sources are connected to the infotainment, an  audio-switch might be required additionally.

• Inserted video-signal can be switched simultaneously to any audio mode of the factory infotainment.

• Note: Only for Comand Online NTG5-205, the optional OBD-coder for factory audio-AUX is available (OBD-N5-X-01).

FAQ – Trouble shooting Interface functions – general
For any troubles which may occur, check the following table for a solution before requesting support from your vendor.

Symptom| Reason| Possible solution|
---|---|---|---
No picture/black picture (factory picture).| Not all connectors have been reconnected to factory head- unit or monitor after installation.| Connect missing connectors.|
No power on CAN-bus box (all LED CAN-bus box are off).| Check power supply of CAN-bus box. Check CAN-bus connection of CAN-bus box.|
CAN-bus box connected to CAN-bus in wrong place.| Refer to the manual where to connect to the CAN-bus. If not mentioned, try another place to connect to the CAN- bus.|
No power on video-interface (all LED video-interface are off).| Check whether CAN-bus box delivers +12V ACC on red wire output of 8pin to 6pin cable. If not cut wire and supply ACC +12V directly to video-interface.|
No picture/black picture/white picture (inserted picture) but factory picture is OK.| No picture from video source.| Check on other monitor whether video source is OK.|
No video-source connected to the selected interface input.| Check settings dips 1 to 3 of video interface which inputs are activated and switch to corresponding input(s).|
LVDS cables plugged in wrong place.| Double-check whether order of LVDS cables is exactly connected according to manual. Plugging into head-unit does not work when the manual says to plug into monitor and vice versa.|
Wrong monitor settings of video-interface.| Try different combinations of dips 7 and 8 of video- interface. Unplug 6pin power after each change.|
Inserted picture totally wrong size or position.|
Inserted picture double or 4 times on monitor.|
Inserted picture distorted, flickering or running vertically.|
Video sources output set to AUTO or MULTI which causes a conflict with the interfaces auto detection.| Set video source output fixed to PAL or NTSC. It is best to set all video sources to the same standard.|
If error occurs only after source switching: Connected sources are not set to the same TV standard.| Set all video sources to the same standard.|
Some interfaces can only handle NTSC input.| Check manual whether there is a limitation to NTSC mentioned. If yes, set source fixed to NTSC output.|
Inserted picture b/w.|
Inserted picture qual. bad.| Picture settings have not been adjusted.| Use the 3 buttons and the interface’s OSD to adjust the picture settings for the corresponding video input.|
Inserted picture size slightly wrong.|
Inserted picture position wrong.|
Camera input picture flickers.| Camera is being tested under fluorescent light which shines directly into the camera.| Test camera under natural light outside the garage.|
Camera input picture is bluish.| Protection sticker not removed from camera lens.| Remove protection sticker from lens.|
Symptom| Reason| Possible solution|
---|---|---|---
Camera input picture black.| Camera power taken directly from reverse gear lamp.| Use relay or electronics to “clean” reverse gear lamp power. Alternatively, if CAN-bus box is compatible with the vehicle, camera power can be taken from green wire of 6pin to 8pin cable.|
Camera input picture has distortion.|

Camera input picture settings cannot be adjusted.

| Camera input picture settings can only be adjusted in AV2 mode.| Set dip 3 of video-interface to ON (if not input AV2 is not already activated) and connect the camera to AV2. Switch to AV2 and adjust settings. Reconnect camera to camera input and deactivate AV2 if not used for other source.|
Graphics of a car in camera input picture.| Function PDC is ON in the interface OSD.|  In compatible vehicles, the graphics will display the factory PDC distance. If not working or not wanted, set interface OSD menu item UI- CNTRL to ALLOFF.|
Chinese signs in camera input picture| Function RET or ALL is ON (function for Asian market) in the interface OSD.| Set interface OSD menu item UI-CNTRL to ALLOFF or PDCON.|
Not possible to switch video sources by OEM button.| CAN-bus interface does not support this function for

vehicle.

| Use external keypad or cut white wire of 6pin to 8pin cable and apply +12V impulses for AV-switching.|
Pressed too short.| For video source switching a longer press of about 2.5 seconds is required.|
Not possible to switch video sources by external keypad.|
SW-version of interface does not support external keypad.| Use OEM-button or cut white wire of 6pin to 8pin cable and apply +12V impulses for AV- switching.|
Interface does not switch to camera input when reverse gear is engaged.| CAN- bus interface does not support this function for the  vehicles.| Cut the green wire of the 6pin to 8pin cable and apply +12V constant from reverse gear-lamp signal. Use relay to “clean” R-gear lamp power.|
Interfa ce switches video-sources by itself.| CAN-bus interface compatibility to vehicle is limited.| Cut the grey wire of 6pin to 8pin and isolate both ends. If problem still occurs, additionally cut the white wire of 6pin to 8pin cable and isolate both ends.|
