Our take on the Sony MEX-BT3700

by Ken Nail
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.

Go beyond just playing music with your stereo. You'll enjoy hands-free calling with your compatible phone when you've got the Sony Xplod MEX-BT3700 CD receiver in the dash. Bluetooth® technology lets you hear calls through your car's speakers, so you can keep your phone in your pocket and your hands on the wheel.

Musical options abound
The MEX-BT3700 brings out the best in your CDs, whether they're store-bought discs or ones you've burned with MP3, WMA or AAC files. The front-panel USB input features Sony's 1-wire connection — plug in your iPod® or many other music players and enjoy convenient control of your music.

You can use the handy front-panel auxiliary input to connect other audio sources. To further expand your options, hook up a Sony satellite radio for commercial-free music, or add a Sony HD Radio™ tuner for superb radio reception and extra programming from your local participating stations.

Strong sound
The internal amplifier offers power and clarity that'll make your music pop with excitement, and you can control and adjust the MEX-BT3700's sound with its 3-band equalizer or seven preset EQ curves. For even more dynamic impact, use the three sets of preamp outputs to connect amps and subs in an expanded system.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

Note: If you're going to use your iPod with this receiver, be sure to check "Details" for specific iPod model compatibility with this receiver.

    Features

    Overview: The Sony MEX-BT3700U single CD receiver is equipped with Bluetooth technology, offering hands-free calling as well as music streaming from a compatible Bluetooth phone or music player. In addition, you can connect other music sources, such as an iPod, HD or Satellite Radio tuner, or CD changer.

    CEA2006 Compliant: The power specifications for the MEX-BT3700 are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Electronics Association (CEA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers. The power output specs for the MEX-BT3700 are as follows:

    • CEA2006 Specs: 17 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Maximum Power Output: 52 watts x 4 channels (208 watts total)

    AM/FM Tuner: The MEX-BT3700U features a built-in AM/FM digital tuner. The built-in AM/FM tuner offers the following features: Auto/Manual tuning, Preset tuning (6 presets each in 5 bands), Best Tuning Memory, Local Seek Mode, and Mono Mode.

    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. The headunit can recognize up to 150 folders and 300 folders and files combined. The unit also displays ID3-Tag information up to 32 characters.

    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.

    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 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.

    EQ3 Stage 2: EQ3 Stage 2 offers 7 EQ presets, each of which has a preset value for 3 bands: Low (60Hz), Middle (1kHz), and High (10kHz). The EQ presets and the band values are as follows:

    • Xplod: Low: +6, Middle: +0, High: +2
    • Vocal: Low: +2, Middle: +6, High: +0
    • Edge: Low: +4, Middle: -2, High: +5
    • Cruise: Low: +2, Middle: +0, High: +1
    • Space: Low: +2, Middle: +3, High: +6
    • Gravity: Low: +6, Middle: 0, High: +2
    • Off (flat): Low: 0, Middle: 0, High: 0
    • Custom: Adjustable -10dB to +10dB for each band (Low, Middle, High)

    Loudness: This feature allows you to listen to your music clearly at low volume levels by reinforcing the bass and treble. The bass level is increased to +4 dB at 100 Hz while the treble level is increased to +2 dB a 10 kHz.

    Preamp Outputs: The MEX-BT3700U contains three pairs of RCA preamp outputs - a front pair, rear pair, and subwoofer (non-fading) pair. The Subwoofer output has an adjustable low-pass filter with a selectable cut-off frequency of 160Hz, 140Hz, 120Hz, 100Hz, 80Hz, or Off. You can also adjust the subwoofer's output phase to Normal or Reverse. In addition, 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 BT3700U has a high pass filter for the front and rear preamp and speaker outputs, with a selectable cutoff frequency of 80Hz, 100Hz, 120Hz, 140Hz, or 160Hz.

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

    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.

    Dimmer: To change the brightness of the display you can set the MEX-BT3700U to one of two dimmer modes - Dimmer Off (deactivates the dimmer) or Dimmer On (display always dim).

    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.

    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.

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

    Remote Control: The MEX-BT3700U comes with the RM-X304 wireless remote commander for operating the basic audio functions of this unit, as well as the Bluetooth Communication functions. Dimensions: Width = 1.667", Height = 3.938", Depth = 0.443".

    Optional Wired Remote Control: This unit also has a 3.5mm minijack input for the optional RM-X4S wired rotary commander. In addition, the PAC SWI-PS steering wheel remote interface is compatible with this head unit. The SWI-PS interface allows you to retain the use of your steering wheel and/or rear seat radio controls when replacing the factory head unit in select vehicles with a Sony head unit with wired remote capability. In some GM vehicles, this adapter allows you to retain heater control buttons as well.

    External Device Controls

    Bluetooth Wireless Communication: The MEX-BT3700U has built-in Bluetooth hardware to integrate with Bluetooth-enabled cellular phones and audio players. Bluetooth (Standard Bluetooth version 2.0) is a two-way wireless communication system allowing you to make and receive cell phone calls, and listen to a Bluetooth audio device. Up to 8 phones or audio devices can be registered with the MEX-BT3700U. You can adjust the volume for each connected Bluetooth audio device from -8 to +18dB. Bluetooth wireless technology operates on a 2.4GHZ frequency band within a range of about 10 meters (about 33 feet). For a list of compatible Bluetooth devices, please visit the Sony e-support website (esupport.sony.com). The MEX-BT3700U supports the following Bluetooth profiles:

    • Hands-Free Talk (HFP 1.5/HSP): Incoming calls can be received through this head unit, and the ring tone is output from your car speakers. Incoming calls can be rejected if desired. To make a call from this unit, only redial is used. To call another phone, you will need to dial the number on your cell phone, and then transfer the call to the head unit. The unit can be set to automatically reconnect to the last connected Bluetooth device when the ignition is turned on. The phone rings, and you hear the caller's voice through the front speakers (left, right, or both). The BT3700U has a built-in microphone located behind the detachable faceplate or your can purchase an external microphone (158XAMC10, sold separately) for added clarity. The MEX-BT3700U also supports Voice Dial Activation which allows you to activate voice dialing with a compatible Bluetooth enabled mobile-phone by saying the voice tag stored in your cellular phone.
    • Music Streaming (A2DP/AVRCP): You can listen to music from an audio device that supports A2DP Bluetooth technology. Cellular phones that support A2DP and have music stored in its memory can be played through this head unit. You can listen to and perform some operations on an audio device that supports AVRCP Bluetooth technology. On some devices, you can pause and resume playback and skip tracks by pressing buttons on the head unit.

    USB Port: The receiver is equipped with a front-panel Type-A USB input for plugging in a USB Mass Storage Class device, or a compatible USB audio player. The head unit can play music files stored on the USB device in MP3, WMA, or AAC formats. The head unit can recognize up to 128 folders with up to 500 tracks each when connected to a USB Mass Storage Device.

    iPod Direct: The front-panel USB input can also be used to plug in, charge, and control an iPod via a single cable for audio playback. This is the same cable that comes with the iPod (Type A USB-to-iPod dock connector), or can be purchased separately (472USBCABL). In Audio Mode, the iPod is controlled by the head unit. You can switch the head unit to Passenger Mode and control the iPod directly using the iPod's controls. The receiver is compatible with the following iPods:

    • iPod video (5th generation)
    • iPod classic (80/120/160GB)
    • iPod nano (1st/2nd/3rd/4th generation)
    • iPod touch (1st/2nd generation)
    • iPod phone/phone3G

    Note: The iPod video (5th generation) and iPod nano (1st generation) does not support Passenger Mode.

    HD Radio Ready: The MEX-BT3700U 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.

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

    • SIRIUS Satellite Radio: To receive SIRIUS Satellite Radio, you can connect the optional SCC1 SiriusConnect Vehicle Tuner and the optional SNYSC1 Sony interface module (package item number 700SIRSONY).
    • XM Satellite Radio: To receive XM Satellite Radio, you can connect the optional CNP2000UC XM Mini Tuner and the Sony CNP-SON1 adapter cable (package item number 700XMSON1).
    • Auxiliary Input: A portable satellite radio receiver, such as the XM 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 (item number 158XA300).

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

    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. 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.

    Junk

    Written By John, Grand Junction, CO on Sunday, August 28, 2011
    Crutchfield Customer Review (What's this?)
     
    i-pod control is very bad, until it quit today. I-pod would quit play when we hit bumps and had to be unplugged and reinserted to the USB. FM reception very weak. Now that this stupid thing broke, after less than 2 years it is time realize what a piece of junk. Replacement for sure will not be Sony.

    Sony MEX-BT3700U CD Receiver

    Written By LarryS, Clyde, NC. on Monday, July 12, 2010
    Crutchfield Customer Review (What's this?)
     
    When you turn it on, this radio works great. Great sound no matter what your doing. Blue tooth, iPod, Satellite radio, CD, whatever. BUT..................
    You have to manually turn the radio AND blue tooth on every single time you start the vehicle. What a pain in the rump that is. I've never in my life seen or heard of a radio in a car that doesn't automatically start right back where you left it. Just imagine if every time you got in your car you had to rearrange all the mirrors and the seat position. It's kind of like that. I don't know what Sony was thinking but it sure does put a bad taste in my mouth. And now that I've talked to their technicians (at least they are English speaking) I'll probably never buy Sony again. I've had several Sony components in the past for home and car and have been very pleased up till now. Engineering something to not work as it's supposed to does not sit well with me.

    Great for music - average for Bluetooth phone calls

    Written By agaurav, Andover, MA on Sunday, July 11, 2010
    Crutchfield Customer Review (What's this?)
     
    I have this for about 7 months now and it has worked just fine. A few points:

    1. Music is great over USB stick, iPhone via USB or Bluetooth.
    2. FM quality is decent as well. I replaced an HD radio so I definitely miss the HD option now.
    3. Phonecalls are just about OK even with the external mic. I placed it at a few different spots but the remote party almost always dislikes the quality.
    4. Biggest issue - the USB option stopped working when I upgraded the iPhone 3GS to iOS 4.0 in July 2010. It now plays music for 5 seconds and stops. Now I have to struggle and put it on Bluetooth for the music. The trouble with that approach is that I have to select that manually every time I start the car since USB is the default option. A real pain plus I do lost the display since Bluetooth audio doesn't send the title information over to the car stereo.

    Crutchfield Customer Review (What's this?)
     
    A great stereo for the money. Pros: Bluetooth phone and music connectivity work great even without an external mic, Great sound, install was super simple with the Crutchfield supplied adapter and wiring harness. Cons: Unable to dim the lights on the faceplate, Ipod is hard to control through the unit and have been unable to switch it to control the Ipod via the Ipod. 5 Stars because of the great bluetooth sound on a low price unit.

    Installed in a 2001 Chrysler Sebring convertible. Works perfectly. Like any other USB stereo, if you constantly take things in and out of the USB port, it gets a little shaky. I also installed the external sony microphone for this unit. It's supposed to attach to your sun visor, but that's no good in a convertible. I attached it to the top of the steering column, behind the steering wheel. Works great.

    Great BT Phone and BT Media Player

    Written By Peter, Austin, TX on Thursday, January 14, 2010
    Crutchfield Customer Review (What's this?)
     
    I installed in my my wife's Infinity QX4, and she loves the BT Phone and media player capabilities. Phone sound quality is great, and people on the other end of the phone cannot tell you are talking on a hands free device.

    Amazingly, the BT media connected fine with her new ATT Tilt2. This was an unexpected surprise since the phone is recent to the market. She is able to play music just fine, and the quality is as if she was plugged in directly.

    Best head unit for my Jeep

    Written By Dento97, Juana Diaz, Pto. Rico on Wednesday, January 13, 2010
     
    Bought to replace the factory unit in my Jeep Wrangler. Straight foward
    intallation with the included instructions. My kids enjoy talking to her mother
    troungh the bluetooth while offroading. The best radio ever bought. The sound is
    great. Why it was discontinued? I was thinking of buying the same unit for my
    daily driver.

    Installed in a 03 Honda Odyssey

    Written By Kenneth, New Orleans, LA on Thursday, December 31, 2009
    Crutchfield Customer Review (What's this?)
     
    Received the Sony MEX BT-3700 as a Christmas gift from my wife (she purchased from Crutchfield). I installed the Sony as a replacement for my stock head unit in a 03 Honda Odyssey EX. Crutchfield supplied all necessary wiring harness adapter, Master Installation Sheet and Receiver Kit. Installation was straight forward with no surprises (the wiring adapter from Crutchfield was the key to an easy installation - I will always buy from Crutchfield when upgrading any car stereo component. You may find the product cheaper elsewhere on the web, but when you factor in the support/adapters furnished by Crutchfield it makes up for any price differential!!!).
    Head unit works as advertised. My Audiovox XM Receiver (Model XMC-10A) plugs right into the AUX input on the front and it sounds so much better now! Built-in bluetooth is pretty much a basic unit (for instance it does not display the incoming phone call Caller ID, but to me it's not a big deal). I have the Bluetooth in the Sony paired to my Blackberry Curve and it works flawlessly. I can dial out from the BB and the Sony will automatically pick up the call. One button to answer incoming calls. People I have spoken to on my Bluetooth cannot tell that I am on a Bluetooth system!
    Sound quality and amplifier is much superior to the head stock unit. You will not be disappointed in the Sony. Strongly recommended!

    Solid Choice, Good price and performance

    Written By pdok, Oklahoma on Monday, December 28, 2009
    Crutchfield Customer Review (What's this?)
     
    I'm very satisfied with this receiver. My main concern was the BT handsfree
    option, and that works very well. I drive an older Toyota and have no trouble
    whatsoever with sound quality on BT phone calls. The receiver does a great job
    of pausing my CD for me, too, when I get a call. Limited redial function,
    however, unless you have voice-dialing set up on your phone (which I don't use.)

    The unit itself has some flaws, which are pretty easy to live with in my
    opinion. There is no way to dim the backlighting, as other reviewers noted.
    True enough, it is bright, but not so much that I "hate" it. It's a little
    disappointing that the dimmer wire in my Toyota is now disconnected, but it's a
    small thing overall.

    The faceplate is somewhat loose, so you can feel it shift around some when you
    tap the buttons. Again, not a big thing.

    There was no 47" A/V Cable in my package, despite what's listed on the site
    here. I don't care personally, since I use either BT or the Aux port for
    external audio.

    The Sony wiring plug seems to have 22AWG wires coming out of it, and that seems
    a little cheap. Sure it's not pushing 500W, but the Crutchfield free harness
    wires were huge by comparison. Thought that could be a little better done by
    Sony. They could also have pre-stripped the ends for me! Every other audio
    product I've bought recently had that done already.

    The one-knob menu navigation is a little cumbersome at first.

    I'd buy it again.

    More Bang for your buck

    Crutchfield Customer Review (What's this?)
     
    This receiver rocks. I put it in my sons Nissan paired with Alpine Speakers and the sound is tremendous. It works great with his IPOD touch 2nd gen. He just hooked it up and was scrolling through his play lists in seconds. The receiver paired with his cell phone in no time. The extra microphone is a must. We mounted it above the visor. Again works great. Very Happy with this purchase.

    I also want to add a special thanks to Crutchfield. The directions for the install were perfect. Right to the letter. I had no trouble setting and installing everything. Remember also the installation gear is free....FREE!. I did some checking around and they wanted to charge me About 50 bucks for the installation gear. Then another 35 dollars to install the receiver and another 120 to install both sets of speakers. That's and extra 205 dollars over the cost of the receiver and the speakers. The time my son and I spent installing everything was about 4 to 5 hours. Please remember though we took our time. Double checking everything. So I saved 205 dollars and spend some time with my son working on a great project. Thanks Crutchfield!

    Very easy to install, less than one hour at home, clear directions, everything you need was included with kit. Great sound, bluetooth reception is clear, recommend external mic for system, picks up some road noise.

    Sony MEX-BT3700

    Written By Jon, Buffalo, NY on Thursday, December 03, 2009
     
    I really like this stereo! I had just the stock factory stereo in my 04 saturn
    ion before i got this. I had already put in 2 12" subs and an amp before the
    stereo, but when i put this stereo in, it made my subs sound 100 times better! i
    really love the bluetooth feature. I have a blackberry curve so when i get in my
    car, it automatically connects to the stereo. then, all i have to do is start a
    song on my phone, and i can control it from my stereo. its soo cool. the
    auxillary ports are sweet too. i love this stereo and im definetely glad i got it

    Crutchfield Customer Review (What's this?)
     
    Just installed the head unit and it is awesome. I need to read the book 100% for all of the features but so far so good. The bluetooth with the external mic is flawless and everyone I've talked to said they can not tell the difference between the bluetooth and the handset.
    I was a little bummed by how long it took to receive it (7 days). I thought 7 days was dumb considering the pony express used to get mail across the country in 7 days by horseback, but the shipping was free so I'm over it. Next time I will pay for the faster shipping.

    Great for the price

    Written By cbsystems, Ohio on Saturday, November 21, 2009
     
    Just installed this in my older Chrysler. Crutchfield tech was very helpful in determining why I could only get sound on tuner mode---my car's built-in Infinity amp needs slightly different connections than normal. Wiring harness and dash kit included free made this a pretty simple job. The included guide to installing speakers and antenna weren't needed, but were a nice touch.

    Pros:

    The stereo sounds great---I was amazed at how much better it sounds than the stock system, which I've always thought sounded pretty good anyway. USB works great, Bluetooth audio works very well, sounds better than expected, and the radio controls will operate my Blackberry's music player. Handsfree calling works pretty well too. Tons of features and fairly intuitive controls. The CD player will play discs that I thought were pretty much unsalvageable. "Zap" button is a nice feature.

    Cons:

    -VERY tight fit in the dash front-to-back --be sure to check whether this will fit in your car.
    -Why doesn't Sony provide a terminal on the unit to auto-dim with the car's lights? My stock radio and even some cheapies I've had in other cars have provided this.


    Overall very pleased with this unit and with Crutchfield's service.

    Nice overall receiver - great features

    Written By Steve, Madison, WI on Friday, November 20, 2009
    Crutchfield Customer Review (What's this?)
     
    I had an Alpine 9852 that I replaced with a Kenwood MP342U that turned out to be a terrible idea and replaced that (thanks crutchfield!) with this Sony BT3700. Reception on the Sony is better than the Alpine and WORLDs better than the Kenwood. Overall features and quality have been great. The bluetooth audio streaming is now a must have feature for me.

    Beeps - mine does not do it on car power off. Never has, never did. I killed the USB beeps by just leaving a tiny SD/USB in all the time. No issue there.

    Lights are bright but not distracting for me.

    Sound quality is very impressive. Cleaner and better reproduction than my Alpine did which is very impressive.

    Had some clipping issues on the bluetooth audio streaming but upped the bitpool on the phone to 64 and sound quality is great now.

    External mic has a hiss in it and cuts off my words if I don't talk loud enough but is great otherwise.

    Definitely recommend.

    I'm a 47-yr old semi-audiophile, and I put this in a 2000 Honda Civic with no additional
    amp, and upgraded front & rear speakers with 6-1/2 and 6x9 Kickers--this combo vastly
    improved my commute. This is our son's college ride, but it's been home this
    semester, so when he gets back for holidays, he's going to be blown away. It's crisp,
    EQ allows plenty of bass, love the 3-level EQ and ability to tune multiple settings. Plenty
    of power for the little car, great IPod control, and very good audio thru the BT mic w/ my
    phone. Have not yet used Sat hook-up, but if I get one of these for my regular-driver, I'll
    probably add that too.

    Great Product!

    Written By Drew, Montgomery, AL on Wednesday, November 18, 2009
    Crutchfield Customer Review (What's this?)
     
    I highly recommend Crutchfield and this product. I recently installed this radio in my wife's 2004 Honda Accord and I had no problems at all due to Crutchfield's excellent easy to follow instructions. The radio works flawlessly and the bluetooth option is a God send. Now my wife doesn't have to dig for her phone when driving nor do I have to listen to her music when I'm talking to her because the radio pauses the music so she can speak through her "free" microphone that Crutchfield included. The only complaint that I have is glare and I wish that there was a way that you could dim the blue lights on the radio because they are extremely bright at night. For the price that is a very small discrepancy.

    Great unit! Does everything I need. Installed it (with the external Mic) in my 1996 Camry and paired it with my 8830 Blackberry. Paired up immediately and works better than expected. Calls are clear and static-free, iPod connection is perfect and allows control from the headunit. Best of all, the unit allows me to make voice activated calls without having to unlock my Blackberry.

    (Haven't tried it with just the internal mic yet, but the external mic is excellent)

    I rarely rate products, but I've been very satisfied with this one. A lot of features at a attractive price. I was looking for USB (or SD) & Ipod support and for just a little extra got bluetooth support. All aspects have worked very well Ipod, USB & bluetooth. Handsfree dialing with my blackberry has been sweet. I don't have an issue with the brightness, perhaps if the unit is higher on your dash and more in the line of sight. Installation was a snap. With the free Mic and wiring harness, Crutchfields price was extremely competitive and you get the backing of the Crutchfields experts, although I didn't need it. I highly recommend this unit through Crutchfield.

    Bluetooth is great, USB could be better

    Written By Anonymous, Amherst, MA on Thursday, November 12, 2009
    Crutchfield Customer Review (What's this?)
     
    The bluetooth function works with my iPhone 3G flawlessly.

    Audio bluetooth:
    Pairs with my phone when I turn the car on. Navigate the Source to "Bluetooth
    Audio" and start playing music using the phone.

    Phone bluetooth: Pairs with my
    phone when I turn the car on. If I'm listening to music, and I get a call, the
    music fades away and I hear a ringtone over my speakers. I press the big dial
    button and it picks up the call on the receiver.

    My order included the Sony external mic which I ran up the side of my
    windshield, inside the plastic between my driverside window and front
    windshield. It's clipped onto my visor. When I talk to people on it, they don't
    know I'm using bluetooth, though they
    can hear some background driving noise or wind. They do NOT hear themselves
    talking due to echos!

    One annoyance is that when I shut my car off, the song I
    was listening to on my phone doesn't pick back up, especially with the USB cord.
    It will also sometimes just not work, and I will need to unplug, and re-plug it
    back in.

    It comes with a remote control, but some useful functions on the
    receiver and remote either don't match up, or are hidden (a learned thing, not
    intuitive).

    The receiver buttons can't be dimmed. The screen dims a bit with a
    menu option, but none of the button and dial LEDs dim. It's annoying at night
    time, and is distracting.

    The construction seems pretty solid, and the volume
    knob has a bit of rubber around it for better grip.

    Best entry level bluetooth/iPod/iPhone receiver

    Written By Edward, Hawaii on Tuesday, October 27, 2009
    Crutchfield Customer Review (What's this?)
     
    This unit is probably the best Bluetooth/CD/iPhone/iPod receiver in this price range.
    The iPod controls are much improved over the Sony CDX-GT610UI, which has painful slow scrolling through songlists and playlists. As a plus, the MEX-BT3700 is a straight physical swap for the CDX-GT610UI. Head unit installation took 5 minutes; remote mic installation took 10.

    iPhone 3G and Blackberry bluetooth integration is great. USB iPod integration (in "passenger" mode) is good.

    Pros:
    Easy management of multiple Bluetooth phones.
    Easy answering of Bluetooth calls.
    Good Bluetooth call quality with external mic.
    Good Bluetooth A2DP streaming.
    Adequate power and fidelity.
    Plays most CD formats.
    Passenger mode iPod control allows control by native iPod interface.

    Cons:
    Awkward access to Bluetooth calling (no dedicated button).
    No receiver-based Bluetooth phonebook.
    Awkward access to souces, with forced scrolling through multiple, inactive inputs.
    Dedicated buttons for infrequently used functions (ZAP, BTM).
    Prominent buttons with no function in most modes (BT, browse).
    iPhone confusion when simultaneously connected to USB and BT (use BT only).

    Awesome receiver. I bought this because I wanted built in blue tooth, great sound, satellite radio compatibility and blue tooth audio. The unit sounds great. The built in blue tooth works like a charm. I've had numerous cell phone conversations using the built in blue tooth and it works perfectly. I paired it with a sirius vehicle dock and play and a sony adapter to control my satellite radio and that also works seemlessly. I would recommend this unit to anyone. In fact, I'm thinking about buying another one for my other vehicle.

    Good Unit

    Written By Mark, Elkhart, IN on Wednesday, October 14, 2009
    Crutchfield Customer Review (What's this?)
     
    This is really a great stereo with a couple of caveats. It works with my iPod
    touch, both plugged into the USB port and via BT. It also works well with my G1.
    When I get in the car, my G1 is ready with BT audio and phone within secs.

    The caveats are that it really does have a glare problem in my 2003 Civic
    Hybrid. At night it is easy to see, but during the day most buttons are
    impossible to read. The display can be pretty difficult as well.

    I think the designers of this unit started out building digital watches in the
    80s. Why in the world someone would design a stereo to beep like this one is
    beyond me. There is a way to turn most of the beeps off, but not the "Caution
    Alarm" and not the USB "Hey, nothing is plugged in right now!" beep. (An
    unnecessarily high and loud beep to boot. I am not sure if it would wake the
    kids, but it might. It is certainly not a "value-add".)

    The "Caution Alarm" sounds when the car is turned off you don't take the
    faceplate off within about 2 secs. Even if I wanted to take the it off, I don't
    think I could do it in time.

    (My father-in-law suggests that the beeps may be an accessibly feature to
    assist blind drivers, but I am skeptical.)

    In the end, I love the features in this stereo. I am getting a lot of use out of
    the BT audio already. If I had to do it all over, I would consider others, but I
    am certainly not going to pull this out and change to another unit.

    My "advisor" didn't mention the mic was on backorder.

    Lots of features for the price, but a few quirks

    Written By John, Minneapolis MN on Monday, October 12, 2009
    Crutchfield Customer Review (What's this?)
     
    Had it in my 01 Mountaineer for a few weeks now.

    Praise:
    - Sound quality improved over OEM head unit. Still have lousy stock speakers, so you can only get so far.
    - BT Audio works flawlessly and pairs easily.
    - Call-interrupt is nice, but iPhone likes to default the speaker source to the Sony. Won't be an issue once external mic arrives (backordered!)
    - Power-on, source switching, and mute/unmute has fade in/out. Nice touch.
    - BT Audio, HD-ready, iPod interface, and remote for under $200

    Nits:
    - Like many others have noted, there is no auto-dim feature (you have to manually select the dimmer mode), and worse - the left side buttons and scroll wheel are obnoxiously bright at night even when dimmed.
    - No apparent way to directly toggle between BT last source. I frequently go between BT Audio and Tuner, but have to scroll thru 6-7 sources to get between the two.
    - The button fonts are awfully small and illegible at a glance. Having a flip-down faceplate for CD loading would help, but I'm sure that would ratchet up the price point.

    This is my first time ordering from Crutchfield, and am very pleased. Wiring harness, mounting kit, instructions, everything was included... if you compare costs - some online retailers are selling the unit for $30-40 cheaper - but by the time you get all the
    installation goods you're well over the price of what Crutchfield is selling it for. Makes it a no-brainer to come back for all my future car audio needs (as budget permits, of course).

    Great Unit

    Written By Adrian, San Francisco, CA on Tuesday, September 29, 2009
    Crutchfield Customer Review (What's this?)
     
    Great product for the price. I wanted a unit which would allow me to play my iPhone through the unit and which would allow me to use a hands-free set-up with my phone. I was actually about to buy a new car almost entirely for these two reasons. Overall I have been very pleased with both Cutchfield and the unit. I have never worked on any part of my car, but with the instructions I had the radio in place in about 2 hours. It would probably take about 45 minutes if I were to do it again.

    I agree with one of the previous reviewers, the unit with the internal microphone is pretty useless for phone conversations, but with the external microphone, there is very little difference in sound quality compared with speaking directly on my phone. It works very well. No difficulty in hearing me. I do find that every so often the volume varies while the other person is talking.

    Playing my iPhone through the bluetooth connection is genius and the sound quality is very clear. The sound quality is better than if the iPhone is plugged into the USB port in front. I have not, personally, found the dimmer nor the beeps when you turn the ignition off to be much of a problem. The three beeps that occur when the ignition is turned off are a bit of a nuisance and I have no idea why they have that function, but it's not the end of the world.

    Sony MEX-BT3700

    Written By Brad, East Tennessee on Monday, September 07, 2009
    Crutchfield Customer Review (What's this?)
     
    I installed this Sony BT3700 about a month ago to replace the existing factory cassette playing unit in a 2000 Ford Focus Wagon. Overall it's an outstanding unit, amazing for the price, and easy to install.

    Installation was pretty easy. The kit fits the Focus perfectly and looks like a factory installation. The kit also provides a small storage space just below the unit which is a perfect size to hold an iPhone.

    It makes the existing speakers sound much better (amazing for a 10 year old Focus), and the radio reception is at least as good as the stock unit.

    It works perfectly with an iPhone, easily allowing in-car phone calls, and music playback via either the USB or bluetooth, which means it can play streaming radio if the phone can find it. The display is too small to allow any decent searching of the iPhone though.

    The only major negative is that there is no way to dim the lights on the unit, other than the display itself, which is about 5% of the light coming at the driver at night. I've started carrying a pad to throw over the unit when it's dark outside.

    Almost perfect

    Written By Bret, Maryland on Saturday, September 05, 2009
    Crutchfield Customer Review (What's this?)
     
    Purchased this for my '97 Z3.
    Installation - easy with kit and instructions - needed support to make sure
    factory amp was powered, they knew exactly what to do.

    Bluetooth - Needs external mike to work well. Mic initally on back order, so
    went 1 month with basic unit built in mic.....noisy and virtually unusable.
    The external microphone should not be an option on this unit - it should be
    supplied with evey unit. Once external mic installed, very usable - even
    with the convertible top down.

    Display has no dimmer connection to headlight use. Display has only two
    manual settings (bright and really really bright!). This is a major distraction
    in my car at night - Sony pay attention and fix this!

    Overall though, sounds great, works well with external mic, and priced
    right. I would buy this unit again - even with the minor annoyances.

    Makes my old car new again!

    Written By Jack, Pittsburgh, PA on Friday, September 04, 2009
    Crutchfield Customer Review (What's this?)
     
    The radio was easy to install with the Crutchfield harness/instructions. Even adding Sirius using the Sony Sirius add-on was easy. The sound quality is excellent with the older Blaupunkt speakers I have in there. The Bluetooth works great. I can now answer the phone and drive the car without worrying about wrecking into someone or something (the car is a manual transmission).

    I use the radio with an iPhone 3G and yes, there is an issue if you have the phone plugged in via USB and you are using Bluetooth. I suspect this is an Apple/iPhone issue and not a Sony issue. I decided to get around the issue by using a USB key that I just keep in the car. The USB key works great and I love how it remembers where you left off when you last turned off the car. That could be great for audiobooks.

    Pros:
    - The Bluetooth is included and works great even without the external mic.
    - The USB function is easy to use and provides a great listening experience.
    - The radio works great with Sirius and the sound quality is great.
    - The EQ settings are good and should be enough for you to get great sound out of your car speakers.

    Cons:
    - The first button where the "channel" buttons are is not for a station. This can be confusing while driving. I need to get used to this.
    - The instructions could be a bit clearer about the iPhone being plugged in and the Bluetooth phone cutting out the sound.

    Mercedes 1996 Install

    Written By Charles, Ridgeland, MS on Wednesday, September 02, 2009
    Crutchfield Customer Review (What's this?)
     
    I have not worked on a Mercedes before and have been putting off getting
    a new radio as I assumed the installation would be a non ending task.
    Every car audio shop I went to assured me that the many hundreds of
    dollars they would charge for installation would be well earned.
    I finally bit the bullet and ordered the Sony radio to replace my factory one
    with the fully faded LCD display. The Sony was backordered, however
    Crutchfield made the manuals available on the web and I downloaded them
    to review. When I did receive the unit I was ready to install and re-cable.
    The supplied adaptor fit the factory cable without modification and I
    matched the wires to the new adaptor with the supplied Sony wires. After
    that we used the Crutchfield supplied guides and tools to remove the old
    radio and clip the Sony connector into place. The radio came up
    immediately and has been working great ever since. I have an old
    analogue phone in the compartment below the radio and found information
    on the web about removal of the phone. The removal added area to work
    in the new wires and connectors without any crowding.
    All my Aux players, Flash USB Drives, and Bluetooth products have synced
    in a matter of seconds and I am a happy owner of a new radio with a great
    display and intuitive controls (well as much as can be expected with all the
    options.)
    Thanks to Crutchfield for all the document help and support.

    Deserving of a 5 but....

    Written By Tom, San Antonio, Texas on Monday, August 31, 2009
    Crutchfield Customer Review (What's this?)
     
    This Head Unit rocks. Very easy to use and has blue-tooth and ipod
    controls built in.

    I am a little disappointed with crutchfield this time. I have been waiting for
    the backordered blue-tooth mic for a couple of weeks now and the required
    bus interface was damaged when I installed my stereo. Crutchfield is
    sending a replacement for the bus interface but did not send it overnight so
    I had to put my dash back together and wait for the remaining parts to
    show up for a complete install.

    I always use Chrutchfield and will continue to use them. I was just a little
    disappointed that my new toy is waiting to be installed because of some
    faulty parts and backordered equipment.

    So close

    Written By Jim, Omaha, NE on Thursday, August 27, 2009
    Crutchfield Customer Review (What's this?)
     
    I just installed this stereo in my 2004 Toyota Tacoma. Installation went very smooth. No problems with the wiring harness.

    Pros:
    I wanted the blue tooth for my phone. I wanted a USB port for a flash drive with my music. Those work well and are easy to use. The mic makes conversations better than ever before. The sound quality is noticeably better than the factory. I am still running factory speakers, so the improvement is only going to be so good.

    Cons:
    There are some limiting factors on what the unit can read on a flash drive: 150 file folders, 500 songs per folder. It doesn't take long to run into the 150 folder limit. The way my folders are set up, I have one folder per group, and one folder per album. Get more than one album per group and you end up with a less than 50 artists available on your flash drive. Any more than that, the unit won't access them.

    Having the USB port on the front of the stereo works well for convenience, but the flash drive sticks out a little far. Given a second chance, I would get the rear mount USB and run an extension to a spot a little less damageable.

    The display is hard to read in sunny conditions. Glare from the sun makes it almost impossible. The text on the buttons is small and hard to read, especially the text over the radio buttons.

    Do I like it. Yes. Would I buy it again. No. Not because of quality or features, because of the small gripes that other units may do better.

    Defective Radio, Great Service

    Written By Jim, Bernalillo New Mexico on Saturday, August 22, 2009
     
    The receiver started acting up, Blue Tooth drop outs, etc. You were out of stock for a replacement when I called Tech Support, but they willingly gave me the offer to send it back with a full refund. You can find cheaper prices, but Crutchfields customer service is the Best. Jim

    Couldnt Be Easier

    Written By John, Richmond. VA on Monday, August 10, 2009
    Crutchfield Customer Review (What's this?)
     
    What a great piece of Equipment. Installation into my chrysler Minivan was a breeze 0 23 minutes... the hardest thing was running the cable for the bluetooth microphone. Mainly bought the unit for its Bluetooth capability. I use an iPhone and wanted wireless audio connectivity and Phone operation as well. Linking the unit to my iPhone took all of 30 seconds and the phone operation has been flawless. Controls take a little getting used to but that is to be expected on a unit with this many features. I had the clock set in 2 minutes(my bench mark for how easy a unit is to use) which was better than the previous Sony unit I had. My wife demanded the unit have preset buttons which this unit has but most units today do not. If seems all the manufacturers are getting away from buttons so they can fill up the display with flashing lights and bells and whistles. Thats a shame. IN the end most of us just want a unit that plays music and perhaps answers a call. This units does both flawlessly. I cant recommend this unit or Crutchfield more highly. Bravo Sony for creating a unit with the correct featurea and still EXTREMELY AFFORDABLE.

    Nice Deck, Right Price

    Written By Steven, Sacramento, CA on Monday, August 10, 2009
    Crutchfield Customer Review (What's this?)
     
    Overall, a great single DIN unit for the right price. Replaced the factory stereo and wife is extremely happy.
    Pros:
    * Works great with iPhone and BT Audio performance is good.
    * Ease of use; easier to use than other decks. Intelligent controls.
    * Very easy to configure and install; sound is excellent, no matter the source.
    * External mic and all adapters included.
    Cons:
    * Bluetooth mic performance is not as good as Pioneer's (using an external mic).
    * Would be nice to have USB hookup in the rear of unit, to hide cable.

    This and my iPhone 3GS...

    Written By Mario, Massachusetts on Saturday, August 08, 2009
    Crutchfield Customer Review (What's this?)
     
    works flawlessly. Bluetooth pairing is automatic and immediate (seconds) after pairing for the first time. After pairing and while streaming wirelessly go ahead and plug in that USB to charge and control your iPhone through the radio as well as see the track being played.

    I maxed this radio out with the SiriusConnectT tuner and adapter package for Sony. (dumped my old plug and play) and yeah..... I'm loving that feature too! 18 FM and 18 SIRI presets along with my iPhone tunes and I can drive to Austrailia without running out of fresh music!

    The blue illumination is not as distracting as I have read in other reviews and my radio sits high on the dash. Nor is the computerized jingle/warning the radio emits when turning off the device.

    Setup was a breeze even with my hitching up the Satellite Radio Package and Crutchfield Customer Service was very helpful with confirming my wiring hook up.

    Now that I'm back on the Crutchfield site I may as well have a look at a nice speaker package.... tweeters would be nice is what I'm thinkin'.

    Not Perfect for iPhone

    Written By Jim, Northwest Arkansas on Saturday, August 08, 2009
    Crutchfield Customer Review (What's this?)
     
    It is very good unit and works with the iphone via usb cable for music and bluetooth for phone. The problem is that it does not seamlessly transition between these modes. I believe this will be corrected when the iphone can stream bluetooth music but this feature is not available yet. If the iphone is connected via cable the bluetooth connection will block the music. If the phone is connected without bluetooth and music comes from the iphone it will cut the music but you must answer the phone directly.
    In all other ways this stereo met and exceeded my expectations. I was also very impressed with Crutchfield instructions. The installation went smoothly. It does play music from the iphone with very high fidelity. Handsfree seems to work well though I haven't tried it on the interstate.

    ILLUMINATION!

    Written By mateychak, Atlanta, GA on Friday, August 07, 2009
    Crutchfield Customer Review (What's this?)
     
    This unit does so many things so well that I hesitate to give it a 3. Unfortunately, the one thing it does horribly wrong is the illumination of the buttons. The dimmer only dims the display and none of the control buttons. I drive a Z3 convertible, and the light from the unit at night not only interferes with the open air night experience, but borders on an unsafe distraction that interferes with your night vision. I've had older SONY Xplod head units that not only dim the entire head unit, but also provide an illumination wire that automatically performs this function when the vehicle lights are selected.

    For those buyers that could care less about lighting, it's a truly great unit with excellent bluetooth hands free, auxiliary inputs, USB etc. It does so many things so well, and this one thing horribly wrong. I may have to change this unit soley based on this one problem. Sony, if you're reading this, PLEASE FIX THIS PROBLEM.

    Bluetooth music streaming!!

    Written By Bernie, Johnstown, PA on Saturday, August 01, 2009
     
    I purchased this unit solely based on the built in bluetooth so I can stream
    music from my iphone, and I am very pleased with it! Installation was a
    breeze thanks to the master sheets and accessories that Crutchfield
    provides. Pairing was a cinch with this unit and the included external
    microphone for calls is a nice touch. The menus are fairly easy to navigate
    and there are a ton of options for tailoring the sound quality to your taste.
    The only draw back of this unit is the lack of a dimmer feature. You can dim
    the display itself but not the buttons. The problem here is that the main
    selector knob has a bright white ring around it which is a little distracting
    when driving at night. This is not a deal breaker in my opinion however, it
    just takes some getting used to. If you're looking for a unit that has built in
    bluetooth I would definetly recommend the Sony MEX-BT3700. FYI for
    those of you that have an iphone, while you can stream music using
    bluetooth you CAN NOT skip/scan tracks directly from the unit.
    Skipping/scanning tracks must be done from the iphone itself. This is not a
    limitation of the Sony unit but of the bluetooth protocol the iphone uses. I
    highly recommend using a good car craddle to keep your iphone within
    reach.

    Great strero for its price

    Written By Jaime, Vega Alta, Puerto Rico on Saturday, August 01, 2009
     
    After a lot of reading and investigation I've got what I was looking for, great stereo, great features, lots of fun.

    Controls are easy to use, work great with my Samsung Behold phone for talking and listening music hands free via bluethoot, tested with an Ipod and with a USB and it keeps impressing me.

    Two thumbs up for Sony again...

    Sony MEX-BT3700

    Written By Tony, Alexandria, MN on Thursday, June 11, 2009
    Crutchfield Customer Review (What's this?)
     
    Controls are easy to use. Works great with my IPhone 3G. Very easy to switch the IPhone between "Direct Control" and "Passenger Mode" if you like to use other apps for music.
    A few nit-picky things:
    If you look through the manual you'll notice that there's settings for changing the dim, but it only changes the dim of the text display, not the buttons, which can be rather bright at night.
    I also haven't figured out a way to disable the security beep (the beep telling you to remove the faceplate when you turn off the vehicle). In the manual it describes a way to "Disable Beep" but that's only for the beep that sounds when you press any button.

    Great Radio

    Written By Cisco, Annapolis, MD on Friday, June 05, 2009
    Crutchfield Customer Review (What's this?)
     
    Very good radio overall. Radio reception is better than stock BOSE system on an 02 Nissan Altima it replaces. Bluetooth connection is seamless .... at least wth a Sony cell phone. Buttons are small and hard to read at times. Use of the microphone is recommended ... those I've talked to say I sound better compared to using the cell phone without bluetooth. Very easy to operate and to learn the features without cracking the owner's manual. Display is sharp and legible in almost all circumstances (haven't checked yet with direct and bright sunlight)

    Hi
    Very nice radio and it works well. bluetooth also works well, I have a loud mustang convertible, and people can hear me with very little wind noise. The mic is up by the visor.
    Installation was quick, the install kit makes it great. had to call to check on a couple wires and they were quick and professional. I use an Ipod plugging in to the usb port and it works great!! It has been installed a couple weeks now!!

    With the mic, people can hear you much better. I have a diesel truck and the background noise doesn't come through the mic.
    Great radio at a good price. Everyone should have one.

    More than I expected

    Written By hitech, Altus, OK on Friday, June 05, 2009
    Crutchfield Customer Review (What's this?)
     
    Bought this to replace the twice replaced failed factory stereo in my wife's Hyundai. I have never owned a Sony receiver before, but I took a chance and ordered this one based on the bluetooth being built in. The audio is very impressive and the bluetooth works great, with a very clear connection. Friends say, the phone connection and audio sounds great. The free Ext. Mic was a neat addition. This unit is fairly simple to use, especially for my wife, who is not very tech oriented. She likes the option of being able to press the volume knob to answer and end calls. The USB and Aux. inputs are a plus. overall this unit is simple yet versatile, and has decent features for the price. The only minor thing I could complain about is not having an auto illumination or dimming control wire. Although You can manually dim the unit through the menu.

    Well Featured

    Written By David, Frederick, MD on Saturday, May 30, 2009
     
    This sony has just about everything you could ask for in a head unit. It works flawlessly with the iPhone over usb for music and bluetooth for phone calls. I recommend the external mic because the internal mic is not as sensitive as it should be. The remote is fantastic and simple.

    Great value

    Written By Eric, Buffalo, NY on Wednesday, May 27, 2009
    Crutchfield Customer Review (What's this?)
     
    Just got the radio last week. Install went perfect, radio works fine. Bluetooth works flawlessly with my LG Voyager. Automatically connects and disconnects when getting in and out of vehicle. Bluetooth mic on faceplate is great, easy to understand both sides of the conversation without need for the external mic option. Nice bright display. Settings for each audio type, so you can get the right EQ mix. Ipod and flash drive work great, ability to search by album and artist, song names stream on display. The multiple EQ settings are great since most of my mp3's are at 128kbps, and need a bit more low end then cd's or radio. Switching usb devices, system remembers where it left off. Overall a great receiver for a good price.

    The bluetooth feature is a must, no longer fumbling with ear pieces or remembering to charge them. Call comes in, music mutes and you can answer, finish call music resumes. Voice dialing also works through stereo.

    Great unit. Works as advertised. Not complicated at all.
    Unlike Kenwood reciever bought several years ago, this unit was easy to understand. I think I will stick to Sony recievers from here on.

    I LOVE THIS RADIO!! typical Sony radio, sounds great, easy to navigate etc. what i really wanted this radio for is the usb interface and external mic bluetooth. My ipod sounds just as good through the radio as it does through headphones (unlike sony's $50 add on piece w/ some different models. DON'T GO FOR THAT OPTION). one of my wife's biggest complaints about my old radio was the bluetooth. she said that there was always an echo when she spoke into her telephone and that it sounds like your on a speaker phone. not the case with this radio and external mic, she says that it's as if i were just talking to her over the phone. GOOD JOB SONY!!
