Display Features

Fluorescent Display: The unit features a large, 4-line full-motion fluorescent display. The dot-matrix text is blue with your choice of backgrounds: 3 spectrum analyzer displays, 3 static wallpapers, a full-motion movie, or combinations of displays that rotate through all categories. In addition, the button illumination can be changed from blue to red or green.

Auto Scroll: This feature allows long displayed items to scroll automatically across the display when the track is changed on a disc.

Dimmer: You can manually dim the display at night, if desired. You can operate the display dimmer automatically, when the vehicle's lights are turned on, or manually. If the dimmer is set to automatic, the orange/white wire in the power harness must be connected to the vehicle's headlight circuit in order to properly work.

Display Illumination/Clock Display: Pressing the Off button once will turn off audio output, but the clock display and button illumination remain on. This makes the clock display and face/button illumination "Keyed" instead of "Unit On" only. To turn the unit off completely, you must press the Off button for two seconds.

Auto Off: When installing in a vehicle without an accessory power wire at the radio location, you can set the unit to turn off all lighting a set amount of time after you turn the power off. The Auto Off feature can be set to 30 seconds, 30 minutes, 60 minutes, or No.

Audio Section

EQ 3 Parametric: You may select one of the following EQ presets: Xplod, Vocal, Edge, Cruise, Space, Gravity, Custom or Off (flat). For the Custom setting you can make your own equalizer settings. You can set the center frequency and bandwidth (Q) for the following bands: Low (60Hz or 100 Hz, Q: 0.5, 1.0, 1.5, or 2.0), Mid (500 Hz or 1 kHz, Q: 0.75, 1.0, 1.25, or 1.5), and High (10 kHz or 12.5 kHz, Q: 0.75 or 1.25). The volume levels of each band is adjustable from +10 dB to -10 dB in 1 dB increments.

DM+ Advanced: The unit features Digital Music Plus Advanced (DM+ Advanced) which uses sound enhancement technologies to improve the sound of digitally compressed audio, such as MP3, WMA, and AAC files from your iPod or USB device. You can turn the feature off/off in the menu as desired.

Dynamic Soundstage Organizer (DSO): The GT930UI features the Dynamic Soundstage Organizer, which uses proprietary circuitry to virtually raise the soundstage and spread it wider across the dash. This is especially helpful if your vehicle has speakers mounted low in the door panels. There are three levels of DSO, each with an increasing amount of effect.

Preamp Outputs: The CDX-GT930UI contains three pairs of 4-volt RCA preamp outputs - front and rear pairs, plus another pair on a 10" pigtail for subwoofer operation. The subwoofer output is non-fading with a low pass filter with a selectable cut-off frequency of 80Hz, 100Hz, 120Hz, 140Hz, 160Hz, or Off. You can adjust the subwoofer preamp output's volume level independently from the head unit's volume control from -10 to +10 in 1dB increments.

High Pass Filter: The Sony CDX-GT930UI features a High Pass Filter which allows you to select the cutoff frequency for the front and rear speakers and preamp outputs from 80Hz, 100Hz, 120Hz, 140Hz, or 160 Hz. You can set the cutoff frequency for the front and rear channels independently or all together.

HD Radio technology, where available, offers higher quality sound than conventional analog broadcasts and receives text data. HD Radio provides FM broadcasts that are equal to CD sound quality and AM broadcasts that are as good as analog FM stereo broadcasts. HD Radio also provides a variety of data, including station name, song title, artist name, album name, etc. Once connected, all AM and FM broadcasts are received by the XT-100HD. HD appears as an additional source, with five preset banks; HD1 (FM1), HD2 (FM2), HD3 (FM3), HD4 (AM1), and HD5 (AM2). In addition to conventional broadcasts, with HD Radio broadcasting it is possible to choose from up to 8 multicast programs (HD1 to HD8 and analog). There are also data programs for each program.

Disc Playback

Disc Compatibility: The CD receiver will play CDs, CD-Rs, and CD-RW discs. The head unit also supports CD Text. The receiver will also play MP3, WMA, and AAC files stored on a CD-R or CD-RW.

Quick-BrowZer: The unit's Quick-BrowZer feature allow you to search for a track on a CD or USB player/memory. When there are many items in one category, you can search for the desired track quickly by using the Jump function which skips in steps of 10% of the total tracks listed in the current folder. Note: When entering the Quick-BrowZer mode, the repeat/shuffle setting is canceled.

Zappin': You can search for a track on a CD or USB player/memory through the Zappin' feature. When the Zappin' feature is engaged, the unit will play a short sample of the track (about 1 minute into the track), then skip to the next track. You can select the length of the sample: 6 seconds, 9 seconds, or 30 seconds.

Eject: The CD disc can be ejected with the power off. The CD player will automatically reinsert the disc if it's ejected but not removed for 15 seconds or more.

The volume level of the auxiliary input is adjustable from -8 to +18 dB to compensate for any difference between the unit and your portable device. The aux input can be deactivated in the menu so it doesn't appear as an available source.

Optional Auxiliary Input: You can connect an auxiliary audio device (such as a portable digital memory player, cassette, MiniDisc, or VCR) when used with the optional XA-300 UniLink Auxiliary Input Adapter (158XA300, sold separately).
