    I have had this receiver a couple months now and it is great. I mostly use it for the blue tooth phone (excellent) and the radio (very clear). I had to knock off one star because it completely resets itself if you disconnect the battery (ugggh).

    Pros: All around great receiver, and with Crutchfield's free extra install parts it was a breeze.

    Cons: It takes about 20 minutes of dedicated attention to do a basic set up for this device, all of which is lost if the battery gets disconnected.

    Easy swap great sound

    I installers this unit in a 2001 Tahoe it was easy because of the tech support from crutchfield . Main body and wiring harness were easy to install but when I finished there was no sound one call to the tech line fixed this the guy new exactly what the problem was . Sound is good and I like the Bluetooth interface also the tuner works well

    Pros: USB. And Bluetooth includes mic so you can make calls through it

    Cons: No scan feature and with so many features it takes a long time to scroll through sources

    Good value, good sound. But the instruction manual is so long. Why is everything so complicated? Fancy lights, tiny controls, when all I really need is a radio & CD player. Who the heck cares about "coolness factor?"

    Rhonda was very knowledgeable and helpful choosing the right unit for my 2004 F150. I wanted Front USB and Bluetooth connectivity for my I Phone 5. I also wanted to be able to upgrade the the unit with additional amps and subs if I choose. This unit provided all of that and for only $20.00 more than a unit with no CD Player and no RCA jacks in the back and this unit has multiple RCA jacks in the back for upgrades. Excellent Bluetooth Connectivity for my I Phone 5. I have not asked my callers how it sounds on their end but on my end bluetooth calls are excellent. The multiple color settings are perfect for my truck and the advanced EQ adjustability allows you to tune the music just how you like it. The Bluetooth syncs right up every time I start the truck. The Sony also has 3 more watts of power than the Pioneer I was considering. I am a complete novice and it was very easy to wire up and install with the Kits included by Crutchfield. I also called with a couple of stupid questions and they answered right away and helped me out.

    Pros: Connectivity with I Phone 5, 17 watts of power, color choices, EQ Settings and ease of install.

    Cons: My vision is not great and the Single Din size vs. the Factory Double Din size makes the buttons small and harder for me to read. I have that problem with most electronics though.

    Be sure to connect power antenna wire for newer vehicles to improve reception, but still not as good as factory stereo reception. Very cool that bt automatically connects and light color can be customized.

    Pros: Cool phone features. Excellent value.

    Cons: iPhone requires USB cable to stream Pandora (while android phone can stream thru bt).

    I love the radio. It sounds and looks great. The display is a little "busy", and it is a little cumbersome to use at first. I wired up the amp wire and was able to leave the "beep" feature on with no security reminder. I have an iPhone 4S and have noticed that if I go to truck to start it and stay in truck it will automatically connect via blue tooth, however if I go to truck, start it and go back in house to let it warm up, I have to go to settings and click on sony in my phone to connect when I go back out to leave. I think the 2 biggest drawbacks if this unit is the fact that it will not display the clock and rds at same time. And scrolling through the menu to get to the one I want seems time consuming. The app feature is Absolutly useless, it doesn't work very well and it doesn't do anything the supplied remote won't do

    Pros: Sound and looks awsome. Bluetooth is very clear on other end. ( others have told me it sounds like I'm in my house with phone to my head, and I drive a dodge diesel ( very loud in cab). Radio display works great

    Cons: Can't see clock. Or if u have click in display u won't see song title and artist. Can be a little complicated to use

    I bought this for my 94 Ranger which had an aftermarket Kenwood that was also bought back in 94. I was looking for something with Bluetooth connectivity and a front facing USB port. When I found the Sony MEX-BT4100 it had just had a big price drop, which is just fine with me as it has everything I was looking for, which makes for a great investment. So far i've had no problems with the unit. The only problem I did have was during installation. The last installer left a real rats' nest for me, but one call to the help line and the pro had me back on track in no time. I will definitely recommend Crutchfield to everyone.

    Pros: Great sound, easy pairing to my cell phone, Looks great, easy to install

    Cons: none

    I had gotten use to the Bluetooth connectivity in my previous car (2012 Mazda 3) and when I started driving my 2003 Lancer, I really missed the hands free calling and Bluetooth audio so I had to get rid of the stock stereo and get something that would be comparable, or better, than what I had in the Mazda. For the price, the Sony MEX-BT4100 CD is a great unit. The installation was pretty easy, though routing the antennae wire for the optional SiriusXM tuner was a bit time consuming. Overall it was a pretty easy job. The only complaint I have is that the first unit I received did not play the radio evenly across left and right channels, everything else seemed to be ok, like the CD and Bluetooth audio, so The folks at Crutchfield sent me a new unit. While I was waiting for it to arrive, I did some more testing and it turned out that only one FM station had the issue with the uneven volume across left and right channels, and I didn't care much about that station, so I went ahead and activated the SiriusXM tuner, but when I tried to access the SAT stations, there was no option for it! So when the new unit arrived, I hooked it up and was able to access the SiriusXM. I still have the problem with the one radio station, but since I don't listen to that station I really don't care. Over all this stereo is excellent, the hands free phone sound quality is great, and the stereo sounds awesome!

    Pros: Lots of configurability in the controls, great value, excellent sound quality

    Cons: First unit I received was defective.

    2003 Element had flaky radio, no AM reception, various issues. Bought this unit. Install stuff made the install easy (less than one hour, local mechanic and I did it.) Ran Microphone to visor edge nearest driver. While folks can tell you are on hands free, no complaints RE ability to use,, understand and have a good two way communication, even at 75MPH in a very noisy car. Wiring Harness and instructions made first time install a snap. Put in unit, still no AM. Hmmmmmm. Checked online re Element, saw it had a roof mounted POWERED antennae (i.e. 12 volts to antennae, must have amplifier in base). antennae slightly loose on roof as well. Ordered new antennae and when it came in took to same local mechanic. Taking apart headliner too get to unit took 20 minutes (lots of plastic trim pieces to remove.) One large nut holds on antennae to body. removes, found some corrosion on antenna plug, checked 12 volts good to antenna with Volt meter, scuffed up where antenna grounds to body via the nut that holds on antennae to body, put it all back together after checking and now - all AM and FM reception perfect!

    Bought radio to fix AM and volume control issues with old radio, plus get hands free blue tooth for cell due to newly enacted Illinois law that requires hands free for cell use. Read manual and it will do whatever you want and then some. Pairs flawlessly with iPhone 4S. Downloaded their ap for iPhone, but haven't tried to use. Good sound, features, front USB/Aux

    Pros: Sound, Blue Tooth, Hands Free Pandora, nice look, loved the free install bits that work

    Cons: OK, you should read the manual, at it's core this device is a sophisticated computer with custom applications to create it's various operational features. Read the book, have less frustration and use more of the unit's capability

    Awesome deck, Love the 7 band EQ. The interface is a little confusing but able to figure it our quickly. The install was a bit tricky because of the lack of remote wire, had to tie in the car wire which made it a bit tough because of the wire length. Not a deal breaker at all because you can always just add some if you have issues. I had enough to not have to add any. Over all I'm super happy with this deck and it sounds great.

    Pros: 7 band eq, looks nice, sounds great, easy to use features

    Cons: No Remote wire, not intuitive display

    Prepare for the color show
