1.2. Check compatibility of vehicle and accessories
1.3. Setting the dip switches of the USB-box USBC-M500
The default dip switch settings of the USB-box
need to be changed ONLY if an after-market
rear-view camera shall be connected or if the AV
of the usbLOGiC shall be deactivated. The dip
switches are located inside the USB-box.
For changes it is necessary to open the box.
Default settings are:
dip1 = ON, dip2 = OFF, dip3 = ON
1.3.1. Automatic switching to rear-view camera
If an after-market rear-view camera shall be connected, in order for
the usbLOGiC to automatically switch to its camera input on engaged
reverse gear,
set dip2 = ON (up).
Note: With after-market cameras, automatic switching works only from
usbLOGiC mode.
1.3.2. Deactivating usbLOGiC AV-input
If no peripheral AV-source shall be connected to the usbLOGiC, we
recommend to disable the AV-input, to avoid customers switching by
mistake to black/no picture of the AV-input. In order to disable the
AV-input of the usbLOGiC,
set dip1 = OFF (down).

3. Installation
Switch off ignition and disconnect the vehicle’s battery! If according to factory rules
disconnecting the battery has to be avoided, it is usually sufficient to put the vehicle in
sleep-mode. In case the sleep-mode does not show success, disconnect the battery with a
resistor lead.

3.1. Connections to the Comand
Place of installation is behind the Comand. Remove the head-unit from the dash-board.
If female 8pin C1 connector of factory harness exists, transfer pins from female 8pin
C1 connector of C2C-MB25 to corresponding slots of female 8pin C1 connector of
factory harness. If slots are occupied remove and isolate factory wires (take notes
before removing).
Otherwise use female 8pin C1 connector of C2C-MB25 instead of factory connector.
Connect yellow loose wire (CAN high) C2C-MB25
to pin 18 of chamber C2. Connect loose blue wire
(CAN low) of C2C-MB25 to pin 17 of chamber C2.
Connect loose red wire of C2C-MB25 to pin 4
of chamber A (+12V battery power).
Connect loose black wire of C2C-MB25 to pin 8
of chamber A (ground).
Plug female 8pin C1 connector of factory harness
(if not existing, of C2C-MB25) into C1 slot of
Comand’s male system connector.
Plug male 5pin DIN connector of harness C2C-MB25 into female 5pin DIN socket on

3.3. USB and optional IR-remote control set
Connect USB-connector of USB-installation socket USBC-EXT to USB-socket of
USB-box USBC-M500 and install the USBC-EXT socket in a well accessible location,
e.g. the glove-box. Make sure there is enough space to load USB-media.
Installation socket for the connection of USB-media.
The USB-IRSET consists of the external C3C-SENSOR IR-sensor and the USBC-RC IR-
remote control and can be used to control the usbLOGiC’s internal USB functions
additionally to the control through the navigations buttons. Connect the C3C-
SENSOR to the female black/red/blue 3pin AMP connector of harness C3C-AVIR and
locate the sensor in an accessible place.
3.4. Connecting peripheral devices
It is possible to connect an after-market AV-source, an after-market rear-view camera and
rear-seat-entertainment to the usbLOGiC.
Before final installation of the peripheral devices, we recommend to test-run the usbLOGiC
functions to detect incompatibility of vehicle, navigation, factory accessories or peripheral
devices as soon as possible.

3.4.1. AV-source
The usbLOGiC has the possibility to connect and remotely control by navigation buttons a
pre-programmed device. The device list in the device control table (appendix A) shows the
pre-programmed remote channels and the related IR-remote cables STA-xxx which must be
ordered separately for the control of the device.
Using the respective STA-xxx IR-control cable, interconnect the yellow female 3pin
AMP connector of harness C2C-MB25 and the IR-port of the AV-source.
Using an RCA-cable, interconnect the female RCA-port AV-IN of the USB-box
USBC-M500 with the AV-output of the AV-source.
The pink ACC-output wire (+12V max 1A) of harness C2C-MB25 can be connected to
the ACC-input wires of the connected device to switch it on. It carries +12V when the
head-unit is running.
3.4.2. Installing AV-source’s IR-sensor additionally
Additionally to the control via OEM navigation, it is possible to install the original IR-sensor
of a connected device. By using the respective Y-adapter (e.g. STA-Y35MM or STA-RJ12) for
the IR-Port of the connected device, the controls of navigation AND device’s IR-sensor can be
connected and used simultaneously. Installation of the IR-sensor is recommended as the
controls via navigation are limited, and not all functions may be covered.

3.4.3. After-market rear-view camera
Connect the video RCA of the after-market rear-view camera to female
RCA connector R-CAM IN of USB-box USBC-M500.
Connect the green wire of C2C-MB25 to the camera power supply (+12V max. 1A)
The green wire is high (+12V) when reverse gear is engaged.
Note: Automatic switching to camera only works from usbLOGiC mode.
3.4.4. After-market rear-seat-entertainment
Using RCA-cables, connect the rear-seat-entertainment to the female RCA-connector
VIDEO OUT of USB-box USBC-M500.
Note: As the output is a full output, not shared with the video signal for the
navigation system, splitting the video with an RCA Y-cable might give a good enough
picture for two rear-seat-entertainment monitors. If not, or if connecting more than
two monitors, use a video splitter.
