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.
