Honda CIVIC 10G 2016 Audio And Visual System Page 1

Audio System Description - Overview
Basic Configuration
The Audio and Visual system consists of a digital audio/video playback function, communication with the customer's device, and
displaying the driver's support information.
Audio Unit
The audio unit acts as a processor which includes playback functions for the USB, Bluetooth
®
audio, iPod for music, and an internal
radio tuner or an external radio tuner that is controlled with digital communication. Select audio functions using the audio unit buttons,
touch screen (touch the display directly to select items on the screen), or the audio remote switch (on the steering wheel).
There are two kinds of audio units according to a vehicle model:
Display Audio Type (7-inch Screen) Color Audio Type (5-inch Screen)
With Navigation ×
Without Navigation ○○
Display Audio Type (7-inch Screen)
The audio unit exists as a Head Unit that controls external audio/visual system related devices which do not have an audio disc player
and a control module. The center display unit is located on the front of the audio unit. An antenna for Bluetooth communication, and
an antenna for wireless LAN communication are built into the audio unit. Audio, Navigation, HFL, and Telematics functions are
installed in the audio unit as application software. As an advanced feature, smartphone linkage and video playback functions are
available.
A
n audio unit with navigation function is referred to as an audio-navigation unit. This unit has a built-in gyro sensor and a navigation
map data (refer to the Navigation System Overview).
The SD card is a storage media that saves the navigation map data. The audio-navigation unit and the SD card cannot be substituted
separately because the SD card module is not a removable type.
Both the audio-navigation unit and the audio unit have a GPS antenna circuit. The GPS information is used for a function that needs
vehicle location other than the navigation function.
For vehicles with Sirius XM
®
radio, the XM receiver circuit is built into the audio unit circuit. The XM satellite/terrestrial signal is
received by the dedicated XM antenna. The audio unit holds XM presets and settings even when the 12 volt battery is disconnected
(AM/FM presets are stored in the tuner unit).
There are two audio systems available for the display audio type:
The system with stereo amplifier: An external stereo amplifier 10 (12
*
) channel output, 9 (11
*
) speakers and a subwoofer are
equipped. The audio unit outputs a digital audio signal to the stereo amplifier.
The system without stereo amplifier: 8 speakers are equipped. In this case, a power amplifier is built into the audio unit.
