Overview
The audio-navigation unit or audio unit acts as the processor for all audio functions. To select audio functions, use one of the following inputs:
Audio-navigation unit or audio unit
Audio remote switch on the steering wheel (with navigation)
Navigation voice control system (with navigation)
The audio display provides the current audio status. For vehicles with navigation, additional audio information is available by touching the audio button on the navigation screen.. The system accepts auxiliary audio inputs using a 3.5 mm stereo miniplug.
The audio unit has a built-in EEPROM (electrically erasable programmable read-only memory). This memory holds the audio presets (AM/FM radio frequency, sound settings, etc.) even when the battery is disconnected.
A security signal is daisy-chained between the audio and vehicle components and integrated into the vehicle's security system.
Speed-sensitive volume compensation (SVC)
The audio system is equipped with speed-sensitive volume compensation (SVC). The audio unit receives the vehicle speed pulse (VSP) from the ECM/PCM. The system processes the speed input and increases the audio system volume level as the vehicle speed increases to compensate for the interior noises that occur at higher speeds. When the vehicle slows down, the volume returns to its normal level. The SVC has four settings: SVC OFF, LOW, MID, and HIGH that can be adjusted using the audio unit. The factory default setting is MID (see the Owner's Manual for more information).
USB adapter
The audio system supports compressed audio files that are saved on a USB audio device and connected to the audio unit through the USB adapter.
The audio unit supports GA-Net address and commands for the USB adapter unit (without navigation).
When the USB device with audio files is connected to the USB adapter, you can select and play the music files using the audio unit controls.
The audio or audio-navigation unit powers the USB audio device through the USB adapter.
Connect the USB audio device using the USB adapter cable located in the glove box (see Owner's Manual).
NOTE: Not all players and player functions work with the USB adapter. See the Owner's Manual for more information.
Muting Logic
The navigation system allows voice control of the audio system and the CD player. Voice control commands are communicated on the GA-Net. When using the navigation TALK/BACK button, the audio is muted on all speakers and you get navigation sound on the front channels. When using the navigation or route guidance (RG), the front speakers give the navigation sound and the rear speakers continue to play. For more information, see the navigation section. The outline of the interruption function is shown in this table.

ATA (PC Card) |
A type of card that is used for playing WMA and MP3 music files in the PC card slot. |
Audio remote switch |
The switches on the steering wheel that control the audio system. |
Auxiliary jack |
Allows the customer to use a portable audio device to input audio recordings. |
Balance |
A control that changes the relative volume of the left and right channels. |
Band |
A range of frequencies between two definite limits. Bands are assigned by the Federal Communications Commission for specific uses. |
Bass |
An adjustment for the low frequency sounds of around 160 Hz and below. |

Allows the customer to play audio recordings stored on their cell phone through the audio system. |
Byte |
A unit of storage for computer files and memory. A CD holds approximately 700 million bytes. |

CD |
A 4.5-inch plastic disc containing digital audio recording that is played optically on a laser equipped player. Never use discs with a paper label. In a hot vehicle, labels can curl up and jam the unit. |
CD changer |
CD player that can store and play more than one CD. Two types are available. Some units accept CDs fed into the changer one at a time, and others accept a magazine (with CDs stacked in a container). |
CD player |
A component designed to play compact disc recordings using a laser optical pickup. The signal from a CD player usually requires amplification. |
CSF (Cold Start Fix) screens |
These screens are displayed if the system requires a GPS initialization. The vehicle should be moved outside into an open area away from buildings/power lines. |
db (Decibels) |
A method of measuring sound or radio signal strength received by the audio unit antenna. |
Distortion |
Inexact reproduction of an audio signal caused by playing music at levels the audio system cannot handle. |
DUET |
A serial data communication line used for sub display. |
DVD (Digital Versatile Disc) |
A 4.5-inch CD-like format used for storing movies with digital audio and video features. The DVD-A format is a DVD format designed for DVD audio systems. Some vehicles can play DVD and DVD-A formats. |
Equalizer |
A device that changes the relative volume of individual frequency bands to suit personal tastes of the listener. |
Fader |
The control that adjusts the relative volume levels of front and rear speakers in a four-speaker system. |
Format |
To prepare a PC Card to receive files this function is done on a PC. Always choose either FAT or FAT32, as the NTFS format is not accepted by the system. Pick the default sectors for the format method selected. |
FM (Frequency Modulation) |
The form of modulation used for radio and television sound transmission in most of the world. Less prone to interference than AM. The FM broadcast band in North America covers roughly 87.7 to 107.9 MHz. |
GA-Net |
The GA-Net allows the audio unit to communicate with all the audio and navigation components in a vehicle. If there is an open in the GA-Net or components, the entire audio and navigation system may appear inoperative. |
GB (Gigabyte) |

Mute |
When the navigation gives guidance, the front speakers are muted (no music). When you use the voice control system, all of the speakers are muted. |
Noise |
Unwanted random sounds like buzzing, hiss, pops, static, whine, etc. |
PC card |
The slot used for playing MP3 and WMA music files. The PC card is usually a combination of a small flash card in a PCMCIA adaptor that slides into the slot. The ATA, SD, and compact flash types of cards have been tested up to 1 GB. |
PCMCIA |
A computer standard for the slot that the PC card slides into. Another term for the PC card slot. |

Woofer |
A speaker that is designed to reproduce low (bass) frequencies only. |
XM radio |
