Straight up and ready to rock

You want your sound strong and your tunes right at hand. Sony built the CDX-G3100UP CD receiver for you. A robust amp design delivers surprising power combined with an accurate, deep soundstage so your favorite tunes deliver an impact that most stock radios just can't match. And if you like to tweak the sound, Sony includes a 5-band equalizer for shaping your tone curve, along with their MEGA BASS feature for pumping up the lows.

Sony CDX-G3100UP CD Receiver

You can adjust the color of the display so it looks right at home in your dash.

Play your favorite tunes

Along with that great sound, this Sony gives you plenty of ways to enjoy your music. In addition to a CD player with MP3 and WMA playback, the CDX-G3100UP comes equipped with a front-panel USB input. You can plug in your iPod® or iPhone® — even many Android™ smartphones — and enjoy control from the receiver, with handy built-in controls to scan and find music quickly. And if you're a Pandora® Internet radio fan, you can plug in your iPhone then browse stations or rate songs from the receiver's controls. The front-panel aux input adds even more options.

Want to keep your steering wheel controls?

In most cars, you'll need an adapter to retain those controls with this car stereo. Connect a few wires, then program the adapter for your particular car and radio, and you'll retain the convenience of your steering wheel controls. You'll see the adapters that work with your vehicle when you add this receiver to your cart.

    Have always been a fan of Sony. After reviewing many other brand's specs, appearance and price, the choice was obvious!

    Pros: Simple to install and has great sound

    First of all, I drive a stripped`down 2002 Ford Ranger. Crank windows. No cruise control. Cloth seats. Paid cash for it in 2009. The factory radio/CD player bit the dust some months ago. Do you know what it's like for a creative person to drive anywhere without MUSIC? Agh. My son, the car guy/music guy/ electronics guy/ fix-it guy recommended Crutchfield. I liked the ease of ordering the right thing for my vehicle. It was a good reasonable price, and arrived promptly and packaged well (that's important to me). My son installed it easily. Nice sound, love all the styling and color changing options (cool), ease of use. Yes, I've hit the wrong button a couple times, but that was in initial use. It's so good to have music again. I'm a classic rock/ blues lover. Highly recommend this company and its products.

    Pros: Ease of ordering and installation. Looks. Style. Fit. Sound. Options.

    Cons: If I'm wearing my sunglasses (it's Texas, so that's 95% of the time), I can't always see the display, but that's b/c my glasses are polarized.

    Nice balance of features at a high school budget. USB and aux hookup make it easy listen to custom playlists, or go right to the presets. Not sure how much the CD player will get used. Would like a higher quality feel for the volume knob.

    Pros: Multiple media inputs. Good value. Easy install with the install kit into my Jeep.

    Cons: A CD player that will never get used, eliminate the player and lower the cost.

    Outstanding sound from a very moderately priced unit, and a huge upgrade from the factory supplied device.

    Pros: Very easy to instal and the extra instructions relating to my car were very useful. I had it up and running within an hour. Great sound from the I-Pod.

    Cons: It took longer to fully understand the menu and programing than it did to instal

    I love Crutchfield's website and installation instructions, and this Sony head-unit is fine for what it is; I'm sad that I didn't read the fine print under the Details tab under the sub-section titled Disk & USB Playback. This unit says: The USB port enables audio playback & control of MP3/WMA audio files stored on your portable USB

    Today, I noticed the next more expensive Sony says this: The head unit can play MP3, WMA, AAC, FLAC, and WAV music files stored on compatible USB device.

    Translation: This Sony will not play music that you copy from your iTunes folders.

    Caveat Emptor!!

    Old Sony went dead and needed a good cheap replacement and this did the job very well. I like my old Sony and this was the updated version of it. Setup is easy and took about 45mins total.

    This was a gift for one of our youth group students graduating from High school. The price was right and the look was perfect for her tastes. It should make a great first deck for her. The scrolling accent colors we knew would be a hit. The aux input and the USB are just what she needed in addition to having a CD player. Her car still has the pathetic factory speakers so I cannot comment on sound quality. It sounds like mud to me, however she says that it sounds 10 times better than it did before.

    Pros: Looks great, priced right, lots of features and inputs.

    Cons: A little more challenging to operate and set-up than the older SONY units that I have purchased in the past

    Made driving way more fun. My previous stereo had no bass and now it's like I have subs! Would recommend. But the install is unclear and said to remove the antenna and get a new cord but after cutting it off we found you could simply remove it. Cost me 3 extra hours and $20 trying to fix the issue. Otherwise it is awesome

    I bought this unit to replace an older single DIN Sony that I thought was going south. I wanted a basic receiver that had a front aux input and a CD player, as well. I reused the old mounting kit and harness adapter and it went in with no problem. Until I turned it on. It sounded great for 15 minutes and then the sound just faded out. Turns out that the speaker in the driver's door was damaged and caused the internal amp to go into protection mode. After replacing both front speakers, the system has performed to my expectations. For a bargain priced stereo, it sounds great with the new Sony 6" speakers. My only quibble is with the very small and oddly shaped buttons that my big fingers have trouble getting to easily. The exception is the easy to use volume dial. Overall, a good value for the money.

    Pros: Ease of installation, front aux and USB port, selectable display colors.

    Cons: Except for the volume control knob, buttons for on/off/source and other functions are very small and oddly shaped.

    Radio is nice and as described but I guess I assumed or didn't think about seeing if it played ACC files from a flash drive (which is iTunes files too I think) which is kinda a bummer. Also can't go back a song when using the flash drive like my older Sony in my e30. Overall a good radio and good upgrade from most stock radios. Has a bunch of LED color options if that's your thing.

    Pros: lots of color settings

    Cons: doesn't play acc or iTunes files off flash drive

    Great Stereo for the price.

    Pros: Easy to use.

    Cons: Display will not dim with dash lights. The display must be manually set to dimmer on or off. It would be nice to have a connection to the dash lights so the display brightness could be controlled with the dash lights rheostat.

    While this radio does have a little bit of a learning curve, it sounds amazing and I love the mega bass button on the front

    Pros: sounds awesome and looks great
