Sony builds wireless Bluetooth connectivity into the MEX-BT2500 CD receiver — make and receive calls without touching your phone while you pay more attention to the road ahead. You can also stream music files from your phone or any device with Bluetooth capability.

For sound quality, not many car stereos can keep up with Sony's ultra-clean CD playback. Slide in a disc, and the MEX-BT2500 recreates the music with incredible clarity and range. The powerful internal amp brings the music to life, while sonic adjustments come from the six preset tone curves and 2-band equalizer.

Bring along your MP3 portable because you can plug it into the handy front panel auxiliary input. The smart button arrangement makes it easy to control this Sony, or grab the user-friendly remote control to make adjustments without taking your eyes off the road.

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 or its optional iPod adapter.

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.

    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.

    Can't beat it for the price.

    Written By Raymond, Wappingers Falls, NY on Tuesday, July 15, 2008

    Everything works and works well for the price. The bluetooth doesn't sound great but it does sound good enough when using the phone. There are a lot of features for the price. Only issue I had was with the installation kit. It's not as flush like the original stereo. It's an issue with the replacement face plate.

    Decent product, one complaint

    Crutchfield Customer Review (What's this?)

    I am happy with the unit, I just have one complaint on the bluetooth. Just like everyone else that has written a review, it would be better if the microphone for the bluetooth phone was on the front of the detachable faceplate instead of behind the faceplate. It works, but with road noise it can be difficult for the person on the other end of the call to hear you.

    Crutchfield Customer Review (What's this?)

    Very good overall with easy, logical controls (I found the controls to be more intuitive than my old Pioneer stereo). The Blue tooth function worked easily. I can hear people fine through the speakers. However, they can't hear me very well. The mic is located behind the face plate, which I found very odd. An external mic on the visor would certainly make more sense, or relocating the mic to the front of the face plate may also help. Aside from the mic issue, this unit performs its main function (playing music) very well. I recommend it.

    Crutchfield Customer Review (What's this?)

    Unit is fine except they do not tell you that some phones may not becompatible. Now I paid to have unit installed and find out that my Treo Smartphone will not work. I then spoke with Sony and their solution is to replace the phone ! Sony should list this on the description, actually Crutchfield should add it! Service at Crutchfield was excellent, I'm deciding wheather to return ths or not and get a more powerfull deck.

    Crutchfield Customer Review (What's this?)

    I bought this because my wife was really uphappy with the Blaupunkt
    Melbourne SD reciever that was in her car. The installation was, as usual
    for Crutchfield, very simple. The car is a 1995 Saturn. The system works
    fine. The bluethooth feature intrigued me and that was it's biggest selling
    point. I use a Samsung T519 cell phone. Pairing went without any
    problems and voice communications is very good on both sides of the
    phone. It could be better, but is more than acceptable. I would not
    hesitate to put one in another car.

    Not bad for the money

    Crutchfield Customer Review (What's this?)

    I bought this unit because this was least expensive way to have BT (Blutooth), front aux & mp3 player. Mp3 plays well, front aux. has lower sound quality than cd, mp3 & radio. Picks up FM & AM radio frequencies fairly well. Overall sound quality is better than what I had before (pioneer mp3 player unit) but has only high and low controls (no mid). BT works ok. I can hear them well on my front speakers but they often have hard time hear my voice (specially when I'm driving over 50 mph) on my 05 Accord. If I buy something else next time, I would get one w/ external mic. & install it somewhere close to visor so people can hear better. BT music stream works fairly well. Once set up w/ your phone, it connects automatically every time you start the car. This unit has no pre-amp wire to connect to any amps.

    Crutchfield Customer Review (What's this?)

    As everybody says, the Crutchfield instructions and harness kit makes installation a breeze. It was an easy fit for my '95 Camry. Compared to the factory radio, the buttons are a little small for my fat fingers, but that's true for all din-mount units. The Bluetooth feature is very cool, even with the stupid placement of the mic behind the faceplate that everyone else has mentioned. The kids love the remote (although I can't figure out how other people use it when they're driving).

    Nice stereo

    Crutchfield Customer Review (What's this?)

    I bought this for my mom for mothers day and her birthday (2 days apart), and I installed it with ease in her 91 Camry, even tho someone had previously hacked the old headunit and and cut the harness!! So my crutchfield advisor emailed me the Toyota harness schmeatic (sp?)

    CD player / radio sounds great
    Bluetooth paired up to my phone (blackberry pearl) perfectly, and hers, the FREE AT&T phone, and sounds great.

    Everything works great on this headunit, it's not designed for expandability, cuz of lack of preouts (ZERO), but this is a GREAT stock replacement headunit and bluetooth unit! Good work Sony! even comes with a remote and FRONT AUX import for her non-ipod mp3 player!

    This is a great product for a basic of users, such as my mom! barely knows how to use her cell phone! hahah

    Crutchfield shipped the product in time with all required accessories to
    install in my Honda Accord. With instruction sheet from Crutchfiled it was no
    big deal to replace my OEM stereo.

    Sound was great and so was the bluetooth feature. You cannot make calls
    through bluetooth except for the redial feature. Overall a great product.

    Excellent Radio

    Written By Ernie, Maywood, NJ on Monday, May 05, 2008

    Crutchfield Customer Review (What's this?)

    This install was a
    pleasure from the
    start. First of
    all, I ordered the
    radio on a Wednesday
    and it was in my
    possession early
    Friday. Very fast
    and efficient

    The install itself
    was a breeze.
    Everything was
    straight-forward and
    easy. I didn't have
    a soldering iron, so
    I elected to
    purchase the crimper
    and make my
    connections. I
    thought this was
    going to be
    difficult and
    time-consuming, but
    to my surprise,
    every wire was
    labeled and color
    coordinated. I
    spliced the
    harnesses together
    and installed the
    radio. I was done
    in an hour, the
    splicing of the
    wires taking up the
    most time. The
    radio performs
    extremely well, even
    with factory
    speakers. Bluetooth
    is also very clear
    and the easy to set
    up. I am extremely
    happy with the
    purchase and the
    overall Crutchfield

    Great bang for the buck. I feel that the Bluetooth works pretty darn good. Great to be handsfree (esp with manual transmission). The remainder of the radio/mp3/cd player performs very well. Also I can't say enough good things about the Crutchfield experience and their support! Thanks.

    Crutchfield Customer Review (What's this?)

    Great stereo. Easy install. Intuitive controls. My last Sony stereo had an attenuate button, which was great for going through the drive through or something, but this does not. What it does have in it's place though, is a pause button that works with the disc player and BT Audio. While I'd prefer the attenuate button that works with every input, this is a good alternative.

    The only other issue I have is that the BT phone is very difficult to hear on the other end when my engine is doing anything but idling because of the engine vibrations. I would have liked to see the mic on the faceplate rather than behind it. Other than that the BT automatically connects with my phone, so I don't even have to think about it.

    FUN Radio to OWN

    Written By Teresa, Rock Hill, SC on Friday, April 11, 2008

    Crutchfield Customer Review (What's this?)

    I purchased this radio for the Bluetooth, satelitle capability and the light colors. I enjoy this radio very much, the remote control is to die for. It is very light weight, easy to control-I can control the radio while keeping my eyes on the road. I have so much fun using my new radio.

    The bluetooth on the other hand---it works fine however the microphone does need improvement. I can hear the caller perfectly but they have just a little trouble hearing me. I still like it very much, it's hands-free and it works for me. When programming your phone/Ipod, etc. read the instructions carefully and following them step by step.

    A good buy

    Written By Lance, New Jersey on Sunday, March 30, 2008

    Crutchfield Customer Review (What's this?)

    This radio more than met my requirements. All I do is listen to the radio on my way to and from work. Occasionally I might play a CD. The BlueTooth and other features that come with the radio I will probably never use. The sound is good and the operation is easy, especially with the remote. What I wanted was a radio for a low price to replace one that didn't work.
    The installation was a pain because of the way the car (a Honda) is built, but the instructions supplied by Crutchfield got me through the process easily even though it took some time. I initially ordered the wrong harness for the car and Crutchfield immediately sent the correct one when I contacted them. I'm happy with the radio and very satisfied with Crutchfield.

    Great receiver, great customer service!

    Crutchfield Customer Review (What's this?)

    I've been doing
    business with
    Crutchfield since
    1993. I will not go
    anywhere else. Their
    customer service and
    technical support is
    outstanding! I
    bought the Sony
    MEX-BT2500 to
    replace the factory
    cassette! on my 95
    Camry. The unit
    arrived the next
    day. Dallas was very
    attentive and
    helpful and blew me
    away when he told my
    receiver would be at
    my home the next
    day. It was.
    I installed it and
    everything worked
    except the tuner.
    All I had was white
    noise and no
    stations tuned up. I
    double checked all
    connections, the
    antenna was working
    with the cassette
    receiver and power
    to it was fine. I
    installed it on a
    Sunday afternoon and
    figured I would call
    tech support next
    day. I talked to
    tech support and
    they gave me a
    couple of
    suggestions which I
    tried the following
    week to no avail. By
    this time I had
    fallen in love with
    the unit. The cd's
    sound great, I love
    the EQ settings and
    you can customize
    the sound to your
    liking. The AUX
    input works great
    also. The reason I
    got this unit was
    due to the Bluetooth
    capability. It meets
    my needs as I get a
    lot of calls due to
    my job and I do not
    like to talk on the
    phone and drive. The
    sound is crystal
    clear, I do have to
    turn the volume down
    as my listeners
    sometimes complain
    about an echo but
    that is not the
    units fault. The
    volume is just too
    high. Once I turn it
    down it works fine.
    So getting back to
    the tuner problem,
    this past Sunday I
    went at it again. I
    took the unit out,
    disconnected the
    antenna and used a
    extended clothes
    hanger as a
    substitue on advice
    of tech support.
    Same result, nothing
    but white noise. I
    had tech support on
    my cell phone while
    doing this and Ray
    told me they would
    send another unit
    out to me right
    away. I was again
    blown away by the
    fast response. My
    new unit arrive
    Tuesday morning, I
    installed it today
    and everything works
    as advertised. I
    keep coming back to
    Crutchfield as they
    always exceed my
    expectations. Sure,
    I checked out other
    websites for the
    same unit and I
    could have saved
    $16.00 but it was
    not worth it to me.
    I really appreciate
    the quick service,
    the free
    installation guides
    for your particular
    vehicle, wire
    harness, and
    everything you need
    for your
    installation. And if
    you run into
    problems tech
    support is just a
    phone call away. I'm
    a customer for life!

    Great for the price

    Great radio for the price. Has all the functions you will need (plays MP3 +
    WMA, front AUX input, Bluetooth phone, remote control - handy for
    passenger to use).

    Downside (none are critical)
    1) can only re-dial last number called using radio (calling using the phone
    automatically connect to the radio..)
    2) no amp output
    3) annoying beeps every time you turn off the ignition (this is to remind you
    to remove the face plate)

    Great features for the price

    Great Stereo

    Written By johnr27, San Antonio, TX on Saturday, March 15, 2008

    Crutchfield Customer Review (What's this?)

    I just installed this stereo on my 1999 Ford Expedition. It took me about 15 minutes to wire the harness, although I did have to buy a crimper and connectors and about 20 minutes to read the included instructions and install into my vehicle.

    Right off the bat the stereo was easy to use and sounded better than my stock radio. The bluetooth works great. I haven't had any complaints from callers on the other end about being able to hear me. They all say they can hear me well. And hearing them throught the speakers on my car is great. I can even hear my wife wispering, which I can never hear on my earpiece.

    Good unit, awesome support

    Written By Eric, Charlotte, NC on Thursday, March 13, 2008

    Crutchfield Customer Review (What's this?)

    I haven't installed a car stereo since the late 80's, so I was a little worried that I might mess this one up. The unit arrived with a great set of instructions showing pictures of my dash! I followed the simple steps and installed it in about an hour.

    But it didn't work. The unit wouldn't turn on, so I called Tech Support and they helped me diagnose the issue in about 5 minutes (I had a bad connection on a power line). After a quick rewire, the unit powered up!

    Sony's user instructions weren't as clear as Crutchfield's installation instructions, but I found them perfectly adequate to help me setup the system (set the clock, channel presets, connect to my Bluetooth phone/media player, etc). The hands-free phone did sound a little strange, but the person on the other end could hear me clearly. I believe she said "You sound like you are in a box, but I can hear you fine".

    I would recommend this stereo to anyone who wants a good system without a huge price tag. I looked at pricier models, but all I really wanted was a solid stereo for a reasonable price. I would further recommend buying this system from Crutchfield. Nothing beats having free Tech Support for installation!

    Nice unit; unbeatable price

    Crutchfield Customer Review (What's this?)

    Our kids are always listening to their MP3 players. We were tired of
    messing with FM transmitters that don't work very well and wanted to
    replace the head unit in both our vehicles with one that has a front
    auxillary jack. After researching numerous units, we decided to buy this

    I installed this unit in my '99 Grand Caravan and my '01 Ram 1500. The unit
    works great and is a huge improvement over the factory units. The tuner
    works fine and the sound is great. The front auxillary jack works great as
    well. I also think the CD player sounds better than the factory unit in my
    Caravan. My Ram had a cassette deck, so, the CD player is great!

    The bluetooth function is a great plus. We have only used it a few times,
    but the sound on both ends of the conversation is satisifactory. Our
    phones connect automatically after starting the vehicle. This is a nice
    feature considering the price of this unit.

    The instructions for setting up the unit are easy to follow, although,
    depending on what source is selected, the menu choices are different. This
    makes the setup a little tedious as you can change settings for each source.

    This was the first time I have ever replaced a head unit in any vehicle. The
    instructions provided by Crutchfield were incredible. The installation was a
    breeze and took no time at all. I presoldered the wiring harness the day
    before. This took about 1/2 hour for both vehicles. I also preinstalled the
    units into the Dodge install kit. This was probably another 1/2 hour for
    both. Once I got into the vehicles, removal of the old units and installation
    of the new units was a breeze. The install kit fit like a glove and was very
    secure. I didn't have to trim anything! Each vehicle took no more than 1/2
    hour and they look great.

    Crutchfield Customer Review (What's this?)

    I gave this 4 stars. If I was rating the features separately, I would have
    given the stereo 5 stars and the bluetooth 1 1/2 stars.

    Great Stereo for the price. The instructions made it really simple to install.
    The stereo is wonderful. I love the BTM feature, as I travel a lot. It takes a
    lot of the work out of finding the best stations in new areas.

    I wouldn't buy it for the Bluetooth capability. The sound in the car is great,
    easy to hear, easy to use. Everyone I've talked to while using the BT
    function says I sound like I'm in a well. I usually just detach the faceplate
    when using the phone, which defeats the purpose of having the blue tooth
    capability. That said, it is well worth what I paid for an inexpensive, good
    quality stereo with some great features.

    Good sound, bluetooth just okay

    Written By case, Columbus, OH on Thursday, February 07, 2008

    Crutchfield Customer Review (What's this?)

    Sound is terrific for a budget stereo. Attractive design and controls are pretty straightforward. Bluetooth sound quality is not the greatest as you are cruising down the road due to road noise, but works very well when you are parked. One downside is it doesn't come with a storage case for the detachable face. I thought that was a standard issue with most stereos nowadays. All in all, though, a very good value and I would recommend it if you are looking for a stereo under $200 with some nice features. As always, Crutchfield delivered quickly and completely.

    Great Receiver, Reliable Bluetooth

    Written By Rob, Memphis, TN. on Thursday, January 31, 2008

    Crutchfield Customer Review (What's this?)

    Reciever is very good at pulling in week stations when traveling (both am & fm) - among the best I've had. Crutchfield does not show this receiver to fit the 87-95 Ford Bronco, but it does, as it is identical to F-150 dash. Used the F-150 install kit from Crutchfield for our 95 Bronco XLT.

    Great power and clarity pushing Polk dB series speakers (also from Crutchfield). The bluetooth phone connection is clear and reliable, despite the wind noise that is notorious in the Bronco. The high installation location of the head unit may contribute to this, as there is no interference from blower vents, etc...

    I would highly recommend this unit to anyone as a great upgrade!

    Good, great, but not the best

    Crutchfield Customer Review (What's this?)

    For years I have trusted only Pioneer brand receivers. I had most others, except Sony, and had problems with all, but Pioneer. I have recently been transfered to another work location and have become more concerned about driving safety. So I decided to purchase this receiver. Why not Pioneer, I am glad you asked. The turning knob they put on these receivers nowadays are junk.
    While Pioneer does have receivers with bluetooth, I didn't want that flimsy turning knob. So I searched for bluetooth ready receivers and was pleased of the decent price and features of this one.
    I have had it for one month now and all in all, I am pleased with it. Compared to the Pioneer SuperTuner 3 it replaced, it's performance is close. The reception is not as great as the Pioneer SueprTuner 3, but then again, it is not a Pioneer SuperTuner 3. The sound is not quite as comparable, but it does perform at an acceptable level. The bluetooth works great on this receiver. I have not had a person to complain at all about the way it sounds. This receiver can connect automatically to your bluetooth phone. The only thing is that you have to dial from the phone, but the receiver will connect automatically. Another great feautre is that it remembers the volume level from each source. For example, I like to keep the volume of my bluetooth phone source at around 20 and the tuner at 8. When I am listening to the tuner and a call comes in, the bluetooth phone kicks in and the tuner connects to the phone at volume 20. When I finish the call, the tuner comes back on at a volume 8.
    If you are looking for a decent blueetooth deck and are more concerned about driver safety than anything else, then this one's for you. It combines a great balance of performance, features, and price for a great choice for most people.

    This radio is perfect for my two hours a day commute. The Cd player is very fast even with mp3 discs. Bluetooth works very well, my cell phone holds about 350 songs and it's great that I never miss a call. The microphone does pick up noises, but I have learned to lean towards the radio and speak clearly . Most people say it sounds like I'm in a tunnel but they can hear me well enough.

I have NO experience with this type of thing, but the directions (with pictures specific to my car) and the mounting brackets that Crutchfield includes (FREE!) made it so easy.

    Crutchfield Customer Review (What's this?)

    After an initial problem with the unit blowing a fuse the second time it was turned on, the unit has performed superbly. (Crutchfield's customer service continues to be superb as they overnighted a replacement to me and this problem has not reoccurred.)

    I had read a number of reviews on this units where it was stated that built in microphone for Bluetooth use was less than adequate and the pickup noisy. I have not found this to be the case. The only noise problem that I had was quickly diagnosed and corrected. Since the radio is installed between two of my dashboard air vents, when the fan is running at high speed the noise that eminates from the vents does interfere with voice pickup. With automatic temperature and fan control, the fan goes to its highest speed when the car is first started. It is August here in Las Vegas and the daily average temperature around here hovers around 105 degrees, so this happens a lot. If I want to use the phone under these conditions, I just have to manually reduce the fan speed to a lower setting. After doing that, I would say the sound quality is at least as good as the On-Star unit which was in my last car. It is my opinion that if somone is having a noise proble, it is due to the noise level in their vehicle and not this unit.

    Everything else about the unit is very satisfactory.

    Good if you don't listen to the radio...

    For the price, I like the unit. The cons are the same - folks constantly tell me they can't hear me on the bluetooth. The other big problem I have is FM radio reception. I live outside of a metropolitan area, and because of that, get intermittent FM reception. I even tried changing the antenna on the car to a higher gain, but to no avail. Sound quality is excellent with the JBL speakers in my car, so I'm stuck listening to CD's and my iPod, which is okay, but I kinda like the idea of being able to listen to the radio, too...

    Great sound quality
    Easy to use
    Low price

    Bad bluetooth mic
    Poor FM reception in fringe areas
    Crowded controls

    Nice, simple bluetooth solution

    Crutchfield Customer Review (What's this?)

    I recently installed this stereo in my 1996 VW Jetta. I had my doubts beforehand - I was worried that the handsfree system would be ineffective, as the microphone is located behind the faceplate and because my car is, well, not exactly quiet on the freeway. But I didn't want a bluetooth system with an awkward external mic, and so far I've been pleasantly surprised. The sound quality from the head unit is good but not amazing - better than OEM, but not quite as good as the Kenwood unit I had before. The controls are straightforward. It was tricky for me to pair my phone with the unit initially (it turns out you have to hold the bluetooth button until the symbol flashes on and off, not just until it illuminates), but now my phone now connects quickly every time I start the car up, with no input needed from me.

    The bluetooth function is basic - if you place or receive a call, the music mutes and the call is played through the speakers. You can use the button on the unit to answer/reject incoming calls, hang up, or redial the last number. However, it does not integrate with my phone's (Blackberry Pearl) voice dialing or phone book, so if you want to place a call to someone other than the last number called, you still need to use the buttons on your phone. Callers can tell you're in the car, but I haven't had complaints; it's like being on speakerphone in the office.

    One other thing to note is that the unit has no pre-amp outputs, so if you're planning to run a sub or amp, beware.

    All in all, for the price I paid (scratch/dent with no scratches or dents) I'm very satisfied with the performance of this unit

    Crutchfield Customer Review (What's this?)

    I purchased this radio to replace my lame 1996 Montero OEM unit. After 11 years, it is a more than welcome change. It features all the needed & recent updates that make the vehicle so much more fun to drive.

    Power is more than enough...
    CD unit work great...
    Aux. Input is an A+ Plus...
    Fast learning curve...
    Really good illumintation...
    Bluetooth works like a charm and has become a necessary item... After using the unit, I have come to understand that owners who criticize it have vehicles with noisy interiors. My experience is so far A+++ and I recommend the it for it's price.

    So far, I have no negatives. Installation could not have been easier...


    nice, but not perfect.

    Crutchfield Customer Review (What's this?)

    i was looking to replace stock HU on ford ranger, along with bluetooth hands-free feature. i didn't really feeling the non brand name thingy, so i opted for this model, which is indeed a great product even if it has some flaws.

    i didn't want to spend top dollars on aftermarket radio since i hardly drive this truck. (my main car has pioneer d3 with bluetooth)

    so here is my review
    - good price.
    - bluetooth works with nearly all phones i've tried.
    - good sound quality.
    - front aux port has separate gain control.
    - quick pairing with the phone after initial set up.

    - built in microphone picks up all the road noise from the hood compartment since its location. other parties hear my voice really clean when the car is parked, or moving slow on local, but found impossible to use on freeway. definitely need revision for external mic input in the future.

    Unbelievable, but not in a good way.

    Crutchfield Customer Review (What's this?)

    I cannot understand why Sony would create such a feature rich deck, but not include even a single set of preamp outputs. I noticed this fact only after my order was shipped, but thought it would not be an issue because the amplifier I'm using has high level (speaker) inputs. Unfortunatly I didn't consider that because the head unit isn't designed to work with an amp the power antenna lead that I'm using as a remote trigger only turns on when listening to the radio. As a result, my amp and sub shut off when I listen to CDs. I guess I'll need to install a power switch. But if I have to tear apart my dash again I may just swap head units. I only wish the Clarion bluetooth unit wasn't white.

    Excellent value!

    Crutchfield Customer Review (What's this?)

    I bought this head unit to replace the stock unit in my 01 Maxima. This Sony was my choice because of the combination of Bluetooth and front panel AUX input to handle an iPod and hands-free calling at a budget price. The Sony exceeded my expectations in every way.

    From the description I knew that it wouldnt provide a full iPod interface or full car-kit functionality for the phone so I wont be complaining about things that I didnt expect to get anyway...especially at 1/2 the price of other choices.

    The BT phone features are great. After initial pairing my phone connects to the receiver automatically whenever I get in the car. With an incoming call the ring tone and callers voice play through the speakers. Mic quality is good enough if you speak loud and clear. Multiple phones are no problem. It may seem complicated but is easy to use once you try it.

    Front panel AUX input works great for all the iPod versions in the house with the cable using headphone jack. FM reception is better than the stock unit. Sound is also much improved, will be even better with new speakers.

    Minor complaints...display washes out in the sun, no auto-dim for night time (you can dim it manually though).

    Installation was straightforward once I got the screws drilled out of the old unit (Nissans fault, not Crutchfields) and the included adapters etc were great. The provided trim pieces made the new unit fit into the dash neatly. Tech support handled my questions with no hold-time or hassle. I bought and recommend the plastic wire connectors for quick and easy connections. Without the stuck screws installation would have taken 2-3 hours

    Crutchfield Customer Review (What's this?)

    First and foremost, the Bluetooth is almost unusable on this unit. On the freeway, no one can hear anything I'm saying. During city driving, I have to yell for people to hear me, and even then they say I sound distant and muffled. I now only use the device to know when I'm getting a phone call (I used to miss a lot of calls b/c I can't hear my phone in the car).

    As for the audio quality for music, it is excellent. It is a huge improvement from the stock deck in my Integra. I have not tried the Bluetooth audio though, as I don't own any Bluetooth audio devices.

    Some other complaints about this deck are that FM reception is very poor. I get a lot more static than I did with my stock deck, but this seems to be a common complaint among all aftermarket decks. Also, the volume control has 30 some levels, but 1-20 are all too quiet for normal listening, and from 20-30 the jumps are too big.

    In summary,

    + sound quality
    + looks nice
    + line-in on front is handy

    + Bluetooth is completely unusable
    + FM reception is poor
    + Volume levels are too far apart
    + No preamp outputs

    Crutchfield Customer Review (What's this?)

    I just installed this receiver, along with 4 new Sony speakers, in my car this week. This receiver with built-in Bluetooth is a GREAT deal! Paired flawlessly with my Samsung (Cingular) A707 Sync phone for both BT Phone and BT Audio functionality. I can stream audio files from the phone wirelessly to the head unit, and the sound is great! When a phone call comes in, the audio playback pauses and I can answer the phone by pressing a button on the stereo's remote or by tapping the volume knob. Audio quality both ways is acceptable when using the phone. Not great, but better than I expected seeing as the microphone is located behind the faceplate! Hang up the phone (again with the remote or tapping the volume knob) and the audio playback starts again. This capability, along with the front AUX jack for an MP3 player and support for MP3 CDs, means I'll always have great tunes on the road.

    I'm not crazy about the front panel on this unit -- the buttons are too small and virtually impossible to use while driving. However, once you get this set up to your liking, you can do most of what you want while driving using the remote -- which is a very user friendly feature.

    This is the third time I've installed a car stereo I purchased from Crutchfield. Their installation gear and instructions are flawless. I highly recommend Crutchfield and the Sony MEX-BT2500!

    Great except the Microphone

    Crutchfield Customer Review (What's this?)

    I think this is a great unit except that the microphone is somewhat lacking. Everyone tells me they can't hear sometimes and I sound very distant. After being told this for the millionth time, I decided to give up. Wish they would have put an external mic on it and then it would be awesome. It connects no problem and sounds fine, but bluetooth phone output was the main reason I bought it. I haven't been able to hook up the ipod with bluetooth since those adapters are either over $100 or they use the wrong password code.

    Excellent for the $$$

    Crutchfield Customer Review (What's this?)

    I have the MEX-BT5000 in my car. That is nice too, but, pricey. I like the hands free phone thing (blue tooth). My wife has an Odyssey (2000). She drives around with our 15 month old and she gets calls and makes calls. So for safety I thought the MEX-BT2500 would be a good set up. And, it is. As the other review said you cannot see who is calling, you cannot store numbers in the unit to make calls (you can in the MEX-BT5000). However, If you push in the volume button for 3sec. it will dial the last number you called from your phone. To get around the stored number issue, we just put the people she normally calls as speed dials on her phone. She picks up her phone, push and hold one button then every thing else is done via the head unit automatically. She is very happy with the sound quality, better than factory. And, she wanted MP3, WMA file playback and now she has that. Also, as the other review said, the person hearing you on the other end says it is an odd sound. My BT5000 has the same issue, maybe not quite as bad. The staff at Crutchfield was awesome!!! Thanks Marie! You get the harness to connect to your factory harness & any hardware free from crutchfield, and shipping was free. I paid 179.00. I get piece of mind that if there is a problem I know who I can go to for help and if I had bought it elsewhere, then I would have to go get the hardware & wiring harness adaptor or butcher my factory harness. That is normally about $20. So, you really don't save. Plus you really get service with Crutchfield. That is tough to find anymore

    Great sound

    Crutchfield Customer Review (What's this?)

    I just installed this unit in my 2004 Ford F150. This was my first aftermarket stereo install since my 1963 corvair... Everything went well, the instructions were great and the entire job took only about 1'1/2 hours.

    The sound from this unit is such an improvement over my factory cd player. The mp3 playback works great with album seek etc. all working like it should.

    The bluetooth connection was the deciding factor on me purchasing this unit. It connected to my samsung A900 in only a few minutes and now it automatically connects when I crank up the truck with no intervention needed from me. However, the bluetooth is rather limited.

    I can:
    - Receive calls by simply touching the volume knob
    - Place calls using my cell phone dialing pad.
    - Hear the person on the other end thru my speakers clearly.

    I can't:
    - Call out with the head unit, no contacts transfer
    - See caller ID on the head unit display

    Also, people on the other end report that I sound "funny" like I'm about 10' from my phone. However they can understand me fine and carry on a normal conversation. I don't know if this is a factor of my cell phone, which is not a highly rated bluetooth device, or this Sony unit. I will try and test it with a different phone and see how that works. If I lean toward the built-in mic and speak LOUDLY it works better.

    For the price and ease of installation I think this is a great buy. It will give you limited but very functional bluetooth connectivity and a great mp3 player. Just be aware that it has functions more like a bluetooth headset and not a full fledged car kit.

    External Device Controls


    Drive-S: The MEX-BT2500 uses 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 x 4 S-MOSFET Power IC produces clear, accurate sound, with little distortion, and a high signal-to-noise ratio.

    Front Panel Aux Input: You can listen to a portable audio device by plugging it into the front panel 3.5mm minijack auxiliary input. Note: The Auxiliary Input needs to activated in the menu as a source before it can be selected.

    MP3/WMA Playback: This unit can play MP3 and WMA files recorded on CD-R and CD-RW discs in ISO9660 Level 1/Level 2, Joliet, and Romeo formats. Each disc should have a maximum of 150 folders and 300 files/folders. During playback, the unit displays any recorded ID3 or WMA tag information.

    Best Tuning Memory (BTM): This feature selects stations with the strongest signals within the selected band and stores them in order of their frequency.

    EQ Lite: You may select one of six EQ presets; Xplod, Natural, Hard, Upbeat, Vocal, or Custom. Each preset (except Custom) has a preset value for bass and treble. For the Custom preset, you can adjust the low (100Hz) and high (10kHz) bands from +10 dB to -10 dB in 1 dB increments.

    Loudness: When the Loudness function is activated, the receiver gives a +9dB boost at 100Hz and a +5dB boost at 10kHz.

    Remote Control: The MEX-BT2500 comes with the RM-X304 wireless remote commander. Dimensions: Width=1.667", Height=3.938", Depth=0.443".

    45-Degree Installation: 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. When power is removed from the switched power wire (the key is turned off), the display does turn off.

    Note: When installing in a vehicle without an accessory power wire at the radio location, you must turn the radio completely off (this defeats keyed operation), or you may wire the accessory power wire of this radio to an alternate source of accessory power to retain keyed clock and face/button illumination operation.

    External Device Controls

    Bluetooth Wireless Communication: The MEX-BT2500 has built-in Bluetooth hardware to integrate with Bluetooth enabled cellular phones and audio players, including the Apple iPhone. 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 eight phones or audio devices can be registered with the MEX-BT2500. Bluetooth wireless technology operates within a range of about 10 meters (about 33 feet).

    Hands-Free Talk: 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 microphone is built into the front of the radio.

    Music Streaming: 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.
