Our take on the Sony CDX-GT310

by Robert Ferency-Viars
Sony

Why replace your factory radio?

Two good reasons - sound quality and cool features. A new car stereo offers power that's superior to most factory radios, along with more sophisticated tone controls. And most car stereos offer built-in or optional features that add safety and fun to life in your car, including inputs for your iPod or MP3 player, Bluetooth connectivity for hands-free cell phone calls, satellite radio or HD Radio reception, and connections for building an audio system in your car.

Take charge of your audio system with the Sony CDX-GT310 CD receiver's EQ3 3-band equalizer. Adjust the treble, midrange, and bass to tune in the sound you like and bring out the best in your music. If you don't have time to fine tune, you can make quick, on-the-fly sound adjustments with the seven preset tone settings.

The CDX-GT310 can play discs loaded with MP3 and WMA files, and the front panel auxiliary input makes it easy to connect your portable player. You can even adjust the level of the auxiliary source so that you don't have to turn up the volume when you switch from the radio or CD player. For other listening options, you can add Sony's iPod® adapter or a satellite radio tuner. A set of preamp outputs is on hand for connecting an external amplifier or powered subwoofer.

    Features
    External Device Controls

    Features

    Drive S: The CDX-GT310 features the Drive S chassis platform. Drive S includes the CD mechanism, audio stages, 12 V power supply, and tuner section. The CD mechanism includes a suspension to resist shocks, a motor that draws less power, and a fast low-current pickup that improves durability and CD playback accuracy. The 52W Peak x 4-channel S-MOSFET Power IC produces clearer, more accurate sound, less distortion, and a higher signal-to-noise ratio than previous designs.

    Detachable Face: The CDX-GT310 features a detachable face for theft prevention. The radio does not come with a protective face case.

    Disc Compatibility: The CD receiver will play CDs, CD-Rs, and CD-RW discs.

    MP3/WMA Capability: The CD receiver will also play MP3 and WMA files stored on a CD-R or CD-RW. Below are the following requirements for MP3/WMA playback.

    • ISO: The unit is compatible with the ISO 9660 level 1 / level 2 format, Joliet/Romeo in the expansion format, and Multi Session.
    • The Maximum number of:
      • folders or albums is 150 including root and empty folders
      • MP3/WMA files or tracks and folders contained in a disc (300 if a folder/file names contain many characters, this number may become less than 300).
      • Displayable characters for a folder/file name is 32 (Joliet), or 64 (Romeo).
      • ID3 tag versions 1.0, 1.1, 2.2, 2.3, and 2.4 apply to MP3 only. ID3 tag is 15/30 characters (1.0 and 1.1) or 63/126 characters (2.2, 2.3. and 2.4). WMA tag is 63 characters.

    MP3/WMA Playback Functions: The CD receiver offers the following playback methods for MP3 and WMA files.

    • Track Repeat
    • Album Repeat
    • Album Shuffle
    • Disc Shuffle

    MP3/WMA Display Information: The CD receiver's display can display the following information: Track number/Elapsed playing time, Disc/Artist Name, Album Number, Album Name, Track Name, Text Information and Clock.

    Note: The Album number is displayed only when the album is changed.

    Radio Tuning: The CDX-GT310 allows you to manual tune or seek tune AM/FM stations. In the Local Seek Mode, the unit will only tune in stations with very strong signals during Seek tuning. The Mono Mode allows you improve poor FM reception by selecting a monaural signal instead of a stereo signal. The radio features 5 memory bands to store and receive AM/FM stations. You can store up to 6 presets in each of the following bands - FM1, FM2, FM3, AM1 and AM2. Other tuner features include:

    • Best Tuning Memory (BTM): This feature selects stations with the best signals within the selected band and stores them in order of their frequency. You can select from FM1, FM2, FM3, AM1, and AM2.
    • Manual Tuning: You can manually tune and find your favorite radio stations one by one for FM1, FM2, FM3, AM1, and AM2.
    • Auto Tuning: You can use the seek button to help you search quickly through the available stations and then choose your own presets from these available stations.

    EQ3 Stage 2: You may select one of the following EQ presets: Xplod, Vocal, Edge, Cruise, Space, Gravity, Custom or Off. For the Custom mode, you can adjust the following bands:

    • Low: +10 dB to -10 dB at 60 Hz
    • Middle: +10 dB to -10 dB at 1 kHz
    • High: +10 dB to -10 dB at 10 kHz

    Amplifier Section: The head-unit's amplifier is CEA-2006 compliant and rated at 17 watts RMS x 4 channels at 4 Ohms and 1% THD. The unit is also rated at 23.2 watts per channel minimum continuous average power into 4 ohms, 4 channels driven from 20 Hz to 20 kHz with no more than 5% THD. Peak power is rated at 52 watts per channel.

    Switchable Preamp Outputs: The CDX-GT310 contains one pair of RCA preamp outputs that can be set for the rear channels or for subwoofer operation. When set to subwoofer, the output becomes non-fading and a low pass filter is activated with a selectable cut-off frequency of 125Hz, 78Hz, or Off.

    Front Panel Auxiliary Input: A front panel stereo 3.5mm mini-jack is provided to allow the connection of a portable audio source. Just connect your portable cassette, MD or MP3 player to this unit, and you can listen to the audio from the portable player through the speakers in your mobile audio system. The aux input can be deactivated in the menu so it doesn't appear as an available source.

    Mounting Angle: For flexibility of installation, this unit can be mounted between 0 (horizontal) and 45 degrees.

    Display Illumination/Clock Display: Pressing the Off button once will turn off audio output, but the clock display and face/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 automatically after a set amount of time. The Auto Off feature can be set to 30 seconds, 30 minutes, 60 minutes, or No.

    Dimmer: The CDX-GT310 feature a dimmer mode to dim the brightness of the display. You can choose from either "Dim On" or Dim Off".

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

    Eject: The CD disc can be ejected with the unit powered off. The CD player will automatically reinsert the disc if the disc is ejected and left on the lip opening of the player for 15 seconds or more.

    External Device Controls

    iPod Ready: You can connect an iPod to this unit and control it via the front panel controls and remote. The optional XA-110IP iPod Control Interface (item #158XA110IP) is required.

    Satellite Radio Ready: There are several options for connecting an optional XM or SIRIUS Satellite Radio receiver to this receiver:

    • XM Satellite Radio: To receive XM Satellite Radio, you can connect the optional CNP2000UC XM Mini Tuner (220CNP20UC) and the Sony CNP-SON1 adapter cable (package item number 700XMSON1).
    • SIRIUS Satellite Radio: To receive SIRIUS Satellite Radio, you can connect the optional SIRIUS SIR-SNY1 Satellite Tuner for Sony (item # 607SIRSNY1).
    • Auxiliary Input: A portable satellite radio receiver, such as the Delphi SkyFi3 or SIRIUS Sportster, can be connected to the head unit via the auxiliary input or the Sony XA-300 UniLink Auxiliary Input Adapter--158XA300.

      Note: A subscription is also required to receive satellite radio programming from SIRIUS or XM.

    HD Radio Ready: The CDX-GT310 is compatible with Sony's optional XT-100HD add-on HD Tuner (sold separately) through its UniLink Bus connection. 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.

    Changer Controls: This unit is compatible with Sony Unilink CD/MP3 and MD changers. In addition, this unit can control compatible Sony Mobile Memory Stick players.

    Multiple Changer Control: A maximum of 5 CD changers, 5 CD/MP3 changers, or 5 MD changers may be connected to this receiver. When connecting CD, CD/MP3 and MD changers, you may connect up to a total of 7 changers (but there must not be more than 5 of one type of changer). When connecting more than one changer to this receiver, you must use the Sony XA-C40 source selector.

    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. The XA-300 uses the Unilink and Bus Audio inputs on the back of the receiver, and allows you to connect an optional CD/MD changer in addition to the auxiliary audio source.

    GREAT DEAL - SOUNDS VERY GOOD

    Written By Bizler, Southampton, MA on Thursday, August 30, 2007
    Crutchfield Customer Review (What's this?)
     
    Installed this yesterday in a 2004 Dodge Ram Quad Cab. I replaced a factory stereo with this deck and Sony XS-V690HP's in the front and Sony XS-V160HP's in the rear. For small money, it sounds excellent. Much, much better than the factory stereo/CD player. Everything I needed came in one, nice shipment. Installation is easy if you follow all the steps sent to you in the Crutchfield directions sheet. Total time spent installing four speakers and the new CD receiver - about 3 1/2 hours.

    Super-Sony!

    Written By Greg I., Mattoon,Il. on Monday, August 06, 2007
     
    I bought this receiver earlier in the year and installed it around Memorial Day. What a gem! I haven't installed an after-market radio in 21 years. Took me a bit because of the time from changing sterios but not to difficult to get in my '99 Dodge Ram 1500. BIG boost over the stock radio.
    Love the number of EQ settings , the frount aux-in, and satellite capability. I was expecting descent sound and functions from it but I just couldn't believe all it had for the price. DEFINITELY worth every penny! Now if I can find the time to put in my rear Kicker speakers I bought through Crutchfield.

    Best Value for the Price

    Written By Lee, Wichita, KS on Saturday, March 17, 2007
    Crutchfield Customer Review (What's this?)
     
    I have a '97 chevy blazer with a six speaker Delco system. About a year ago I decided to upgrade my speakers when 2 of them started to go bad. I replaced all six with Focals that sounded awesome from a local car stereo dealer. I was disappointed in the sound once they were installed in my truck. So this year I repaced my factory head unit with the Sony CDX-GT310. I wanted a head unit that I could easily connect my sons iPod to, play my MP3 disc on and had a custom EQ setting. After a week of research, online and the local dealers, I decided on the Sony CDX-GT310. The Sony CDX-GT310 had everything that I wanted. For the price you get more of everything than the other car receiver manufacturers. You get more EQ pre-sets, plus one for a custom setting. Even the presets can be adjusted according to the owners manual. You get better FM sensitivity and CD signal-to-noise ratio than the other manufacturers in this price range. You can even adjust the sound level of the auxilary input. Basically, you get more of everything for the money. I do have one minor complaint though, the onscreen display is unreadable when i open my sunroof. Best of all, my Focal speakers are truely singing now with this Sony head unit. It is just so amazing how much life this Sony head unit has brought to my sound system. to put it quite simply... IT ROCKS!!!

    I've always been a fan of Sony products, and this one keeps my faith in Sony alive. Well laid out, easy to operate, display is visible in all kinds of lighting, and above all else, sounds great!
    I REALLY like the front aux-in, which makes connecting my MP3 player or satellite radio a breeze. I wish more stereo makers would take note of this and quit putting the aux-in's on the rear.

    This unit installed easily and required no re-enginering. Eaze of operation has a learning curve some will not achieve readily. Compared to many other similar units, this one gives more for the money and provides much listening pleasure through custom adjusted settings and even preprogrammed settings.
