Special information Video interface connection The product supports Plug&Play ("jack-to-jack ) connection to LVDS cable between the stock 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). Configuring DIP switches on the video interface body Switch No. ON (down position) OFF (up position) 1. RGB input On Off 2. AV1 input On Off 3. AV2 input On Off 4. RGB input display resolution 5. Camera selection 800X480 If the vehicle has a rear view camera connected to the video interface Toggle down once for IR 480X240 If the vehicle has a factory-installed rear view camera 6. Programming or calibration mode programming Normal use 7. Not usable - Always up 8. Not usable - Always up 7

Display configuration buttons on the lower panel There are Menu, +, and buttons on the video interface lower panel that one can use to configure how the image from the video interface will be displayed. To access the image settings menu, press and 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. IR-AV1/AV2: IR control settings menu for devices connected to AV1/AV2. When"None" value is set, control buttons will not pop up when you tap the touch panel.

V-SIZE: vertical image size adjustment. Note. Depending on the car model, the type and the number of settings may vary. 8

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. 9

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. 15

No image/ black screen (manufacturer image). Troubleshooting Malfunction Cause Possible solution Not all plugs have been connected to the stock head Connect the remaining unit or monitor after installation. plugs. No power supplied to CAN unit (not all CAN unit LEDs lite up). No image/ black screen / white image (picture insert) or manufacturer logo is displayed incorrectly. Incorrect image size or positioning. Inserted image is doubled or 4 pictures are displayed on the monitor. Inserted image is distorted, flickering, or displayed in black and white. CAN unit is connected to CAN bus in a wrong place. No power supplied to the video interface (not all video interface LEDs light up). No image from the video source. Video source is not connected to the selected video interface input. LVDS is connected in a wrong place. Incorrect video interface image display settings. Video sources connected to the video interface operate in different video signal standards. Check CAN unit power supply. Check CAN bus and CAN unit connectivity. Consult the manual for information about CAN bus connection. Check whether CAN unit is connected properly. + 12V (ACC) voltage must be supplied to the red wire output on CAN unit terminal. Check the video signal on a different monitor. Check whether the settings of video interface DIP switches 2 and 3 matches the configuration of connected devices. Check how LVDS cables are connected; consult the manual if needed. 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. 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. 16

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. Video interface operating modes fail to change when the stock button is pressed. The interface fails to switch to camera input when the reverse gear is engaged. Video interface switches between video sources on its own. PDC function is enabled in the video interface image settings. CAN unit does not support changing video interface operating modes with the stock button in this vehicle. Button presses are too short. CAN bus does not support this function for this vehicle. CAN unit compatibility for this vehicle is limited. Parking sensor guide lines are displayed in compatible cars only. If you do not need this function, disable it in UI- CONTROL menu. 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. A longer button press (about 2.5 seconds) is required to switch to another video source. 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. Cut the gray wire coming from CAN unit and insulate both of its ends. If the problem persists, cut the white wire as well. 17
