multimedia system and the monitor.
Note. Video interface is connected without damaging stock wiring and there is no need to modify stock
cables and jacks. To control the video interface, one needs to install an optional 7” touch panel
(glass\plastic).
Switching between modes
To enable the video interface display mode and switch between its operating modes, one can do the
following:
Press and hold NAV / BACK / FAVORITE keys on the control panel.
Press the remote button (comes in the package).

hold “Menu" button, which will bring up the settings window. Use "Menu" button to switch between menu
items and "+", and "–" buttons to change settings.
Contrast: image contrast adjustment.
Brightness: image brightness adjustment.
Saturation: image saturation adjustment.
Position-H: horizontal image adjustment.
Position-V: vertical image adjustment.

Touch panel calibration
One needs to calibrate the touch panel to ensure its correct operation. Calibration menu pops up
automatically when you switch on the video interface for the first time. To calibrate the touch panel, tap
the icons appearing on the screen as accurately as possible. Once the calibration procedure is complete,
press Android logo (for Gazer VI700A-PCM31 model) or OK button (for Gazer VI700W-PCM31 model).
Caution! If the SD card slot is empty or DIP switch No. 6 is set to "On", the touch panel calibration
procedure will have to be repeated on every startup.
Audio connection
There are several ways one can arrange audio playback from the video interface:
1. Connection via Bluetooth in audio transmission mode (for VI700A-PCM31 only).
To do this, connect the stock multimedia system to the video interface via Bluetooth. Then select “Only
audio” in the video interface Bluetooth settings. This is required for correct operation of Hands-Free
function when a mobile phone is connected to the stock stereo system. In this case, when the engine is
running and all equipment is fully operational, two devices (the phone and the video interface) will be
simultaneously connected to the stock stereo system. The phone will operate in Hands-Free mode, while
the video interface will playback all navigation system voice prompts as well as audio tracks.
2. AUX input connection.
In this case, the audio output of the video interface (”AUX” jack) is connected to the “AUX” jack of the
stock multimedia system. Depending on the car model, such connection requires reconnecting the AUX
cable (from the car stereo jack) on each multimedia system startup and then selecting the “AUX” audio
source in the stereo system menu.

One needs to disassemble the display for touch panel installation. There are several display size options
for these multimedia systems. To select the correct touch panel, one needs to measure the display size in
inches and then find a matching touch panel. The touch panel is installed between the plastic panel and
the display image sensor. The panel must be secured with adhesive tape prior to installation.

Troubleshooting
Malfunction
Cause
Possible solution
No image/ black
screen
(manufacturer
image).
Not all plugs have been connected to the stock head
unit or monitor after installation.
Connect the remaining
plugs.
No power supplied to CAN unit (not all CAN unit
LEDs lite up).
Check CAN unit power
supply. Check CAN bus
and CAN unit
connectivity.
CAN unit is connected to CAN bus in a wrong place.
Consult the manual for
information about CAN
bus connection.
No power supplied to the video interface (not all
video interface LEDs light up).
Check whether CAN
unit is connected
properly. + 12V (ACC)
voltage must be
supplied to the red wire
output on CAN unit
terminal.
No image/ black
screen / white image
(picture insert) or
manufacturer logo is
displayed
incorrectly.
No image from the video source.
Check the video signal
on a different monitor.
Video source is not connected to the selected video
interface input.
Check whether the
settings of video
interface DIP switches 2
and 3 matches the
configuration of
connected devices.
LVDS is connected in a wrong place.
Check how LVDS
cables are connected;
consult the manual if
needed.
Incorrect image size
or positioning.
Inserted image is
doubled or 4
pictures are
displayed on the
monitor.
Incorrect video interface image display settings.
Change the combination
of video interface DIP
switches 7 and 8. To
ensure correct
application of modified
settings, reconnect the
power supply every time
you change the position
of DIP switches. Use
image configuration
buttons available on the
video interface.
Inserted image is
distorted, flickering,
or displayed in black
and white.
Video sources connected to the video interface
operate in different video signal standards.
Set the same video
signal standard for all
video sources (PAL or
NTSC).
If the error occurs only after the video source is
turned on.
Use one video standard
for all video sources.
Some video interfaces can process NTSC video
signal only.
Set the video source to
NTSC standard.
Poor quality image.
Incorrect image settings.
Use 3 buttons on the
video interface body to
configure image display
parameters.
Incorrect image
size.
Incorrect image
positioning.
Black screen
instead of camera
feed.
Camera draws power directly from the reverse light.
Use an extra relay to
ensure signal stability.

17
Distorted camera
feed.
Unable to configure
the backup camera
image.
Camera image configuration is available in AV2
mode only.
Set video interface DIP
3 switch to ON (if AV2
input is not activated
yet) and connect the
camera to AV2. Then
switch to AV2 and
configure the image
parameters. After that,
connect the camera to
the camera input and
disconnect AV2 with a
DIP switch if this input is
not in use.
The display shows
parking guide lines
although no parking
sensors are
installed.
PDC function is enabled in the video interface image
settings.
Parking sensor guide
lines are displayed in
compatible cars only. If
you do not need this
function, disable it in UI-
CONTROL menu.
Video interface
operating modes fail
to change when the
stock button is
pressed.
CAN unit does not support changing video interface
operating modes with the stock button in this
vehicle.
Use an external button
for switching between
modes. You can also
use the CAN unit white
wire to switch between
video sources. This
requires supplying it
with + 12V of power.
Button presses are too short.
A longer button press
(about 2.5 seconds) is
required to switch to
another video source.
The interface fails to
switch to camera
input when the
reverse gear is
engaged.
CAN bus does not support this function for this
vehicle.
Cut the green wire
connecting CAN unit
with the video interface
and supply + 12V from
the reverse light. Use an
extra relay for a stable
signal.
Video interface
switches between
video sources on its
own.
CAN unit compatibility for this vehicle is limited.
Cut the gray wire
coming from CAN unit
and insulate both of its
ends. If the problem
persists, cut the white
wire as well.
