Our take on the Pioneer AVIC-U310BT

Enjoy your music and stay on track with Pioneer's AVIC-U310BT navigation receiver. This double-sized receiver sports a CD drive for your favorite discs, whether store-bought or loaded with music files, and features a 4.3" touchscreen for viewing navigation maps and controlling the system.

Enjoy your music and stay on track with Pioneer's AVIC-U310BT navigation receiver. This double-sized receiver sports a CD drive for your favorite discs, whether store-bought or loaded with music files, and features a 4.3" touchscreen for viewing navigation maps and controlling the system.

Easy, accurate navigation
The receiver gives you access to maps of Canada and the entire United States, and its easy-to-read display lets you take in map info with a quick glance. Its text-to-speech function will announce actual street and landmark names to you, so you'll be certain you're on course. You can even detach the navigation screen, take it inside, and plot your course in the comfort of your easy chair.

The SD card slot provides a portal for upgrading and updating your nav information (no music playback). Pioneer's optional CNSD-OP003 upgrade card provides over 12 million points of interest. Got an iPhone®? Pioneer has an app that lets you find a location with your iPhone, then transfer it to the receiver for turn-by-turn directions. Search for "AVIC feeds" in the iTunes app store.

Packed with cool features
Built-in Bluetooth® allows hands-free calling with compatible phones. The USB input input lets you plug in thumb drives loaded with music files and control most iPod® models as well. You'll find your favorite playlists, artists, and albums in a flash with the touchscreen controls.

Sound quality doesn't take a back seat to convenience, as a powerful internal amp, 24-bit digital-to-analog converter, and a 3-band parametric EQ ensure excellent audio performance. Pioneer's Advanced Sound Retriever (ASR) replicates high-frequencies lost in compression, so digital music files won't sound flat and listless.

System expansion
Add a satellite radio tuner or HD Radio™ tuner for even more variety in your entertainment. Use the two sets of preamp outputs to add external amps into your 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 the iPod adapter for specific iPod model compatibility.

    Love it!!!

    Franco from Atlanta, GA on 6/4/2010

    Read many reviews, and could not find anything with all these features with such great audio quality reviews in this price range. I will have to check and see what firmware version comes with my radio, as I have not experienced any of the lock ups that so many reviews are commenting on. SOUND - Excellent, customizable enough to tweak it to my liking as different songs come on from my flash drive. It has made such a difference in the entire sound system, that I no longer feel like having to replace the factory speakers like I was planning to. BLUETOOTH - Connects to my phone seconds after I turn on the key, and the sound is great! It interrupts the music and then resumes playing after the call GPS - Though the screen is the same size (4.3"), it provides guidance regarding which lane to stay on when driving through exits, etc. I also like how it displays signs for the interstates, etc. and how it brings a bar on the side that wears off as you approach the turn. Other than that, I have not used the AVIC feeds program, though the way the left out such important POI category for restaurants!!! Obviously they want people to purchase the optional POI card, but again, I rarely go out of town in my car, so not too important. I definitely recommend it to anyone having the same priorities I had.



    Update the Firmware

    SP from Gulf Coast on 5/18/2010

    Crutchfield Customer Review (What's this?)

    I just installed mine in an 05 Camry. It was the easiest install I've ever tackled. including routing the GPS antenna and Bluetooth mic. I'm even considering adding HD Radio soon. The reception is a step up from the factory radio, which was better than most of my friends' radios. I also like the signal strength display. The ipod control (which was the main reason for the upgrade) works smoothly, and I like how you can link music by artist or album. That means, if you like a song, with one tap on the screen, the rest of the songs from that album are now qued up. The only negative, as others have said, it locks up frequently, but after I updated the firmware to 1.0003 it hasn't happened (to upgrade the firmware, you will need an SD card. That's the only reason I didn't give it 5 stars.



    Great New Head Unit

    Adam from Williamsport, PA on 4/23/2010

    Crutchfield Customer Review (What's this?)

    I was worried this unit would be hard to install myself but everything went in smooth. My only complaint is that the new unit does not mount flush with the mounting bracket. It has two hookps in the back for a stereo. It controls my phone, IPOD and get from a to b. I haven't jumped into controlling my stereo a whole lot yet but it def. sounds great hooked up. The price was phenomenal. One thing to watch out for is that when i drive i pass the roads before it says i do on the nav screen. Don't worry you will be happy with everything this head unit can do for the price!



    Good Unit With Some Flaws

    Thomas from D/FW area on 4/18/2010

    2010 Jeep Wrangler Unlimited
    Crutchfield Customer Review (What's this?)

    Overall, I'm satisfied with the unit. However, I purchased it for Bluetooth, both for the hands-free phone and audio streaming, but it doesn't have the audio streaming Bluetooth feature. Other than that, I've been very satisfied with the purchase. My biggest issue during install was that, for those of you installing in a JK Jeep, there's a bracket against the firewall that the instructions say needs to be cut to fit this unit. Rather than spend time modifying the bracket, I removed it completely, which simplified the install tremendously. My recommendation is to not even contemplate cutting this bracket, just remove it entirely. One other small issue was that the european-style antenna adapter needed one of the nubs shaved off so it would fit the stock antenna plug (simple mod). After using the unit for just over a week, I'm very satisfied with how it works and it's features. Pros: low cost, easy to use, navigation and hands-free Bluetooth included, iPod/Phone control, AVIC Feeds iPhone app, removable faceplate can be used as a map (but no GPS capability when disconnected), firmware upgradable. Cons: (for me) complex install, no audio Bluetooth streaming, very limited out-of-the-box POI database - cost for POI upgrade.

    Crutchfield Customer Review (What's this?)

    Honestly i read the reviews and was like oh it cant be that bad and maybe its me but for the price it should run like a dream....but 9 out of 10 times i get in my truck and crank it the screen cant even use the gps for having to reset the thing ALL the time. When it actually works its a good unit but i have had the unit for four months and it has worked maybe 10 time out of a 100. Would not recommend this pioneer unit at all...Go with a more expensive one that way you dont waste your money...



    Why the complaints?

    Crutchfield Customer Review (What's this?)

    Was looking for a decent double-DIN bluetooth/gps receiver for my new car. I decided to give this unit a try. Based on the reviews I didn't know what to expect... Much to my surprise -- This unit is great! I DID update the firmware out of the box. The bluetooth works great for both talking and listening on your calls with the provided microphone. It's small, so you need to place it smartly. Syncs my Blackberry 8320 fine and uploads my contacts without an issue. I was also worried about the lack of POI's on the GPS but it's not an issue. This unit has the ability, through AVIC Feeds, to take you to a grid coordinate! I travel to a lot of new locations for my work and it hasn't steered me wrong yet. Takes about an hour to get the AVIC Feeds software down but the ability to create groups of POI's by grid coordinate is phenomenal! The GPS can be confused if you go somewhere that it isn't expecting but within 5 minutes it picks you back up and starts directing you again. Has happened to me twice in three weeks. The stereo plays CD's, MP3's, and external USB devices fine and the sound quality is worlds better than my factory stereo. Gear provided by Crutchfield made installation a snap. Even installing a control module to maintain the factory warnings/sounds was a breeze. I HIGHLY RECOMMEND THIS UNIT!

    ghostbay87 from Des Moines, Ia on 3/7/2010

    This unit is great. I've had it for about a month now and had little problem with it. The usb hook up works great. I use it with my palm pre and it works perfectly fine. The nagivation has a bit of an issue with the city that I am in. It pulls up other cities instead of mine but I really don't use it that much anyways. The sound quality is get! It also works great with my 12 in subwoofers. I also like the screen coming off for added protection against theft. I think its worth the price!! Great quality!



    Very Happy!!

    2006 Nissan Frontier
    Crutchfield Customer Review (What's this?)

    I installed this unit in my 2006 Nissan Frontier about a week ago. I did much research and selected this unit based on the functions it offered and the price. So far I am very happy!!! The install went smooth and took about 3.5 hours once everything was closed up and the truck cleaned. I don't use an Ipod but the cable is handy if needed. Also I dont plan on using the Bluetooth because I dont talk on the phone that much so I didnt install that equipment but can in the future if necessary. I wanted navigation, CD playback and the ability to play my Zune. The sound quality with the Zune and CD are amazing, but the 1/4 inch aux input is in the rear of the unit and I was forced to route the cable under the trim next to the shifter and parking brake and into the armrest storage compartment which turned out nice!! The navigation has alittle bit to be desired but I will deal with it because it is a built in unit and allows my truck to be free of GPS window mounts. I plan on purchasing the SD card that will increase the POI's and hope that will make the Nav more productive. The controls are easy to use and figure out for your self without the manual. But if needed the user manual is on a CD which is nice. I just brought my laptop out to the truck and played with the unit for about an hour.The best thing about this unit is the price and it looks super clean in the truck! Thanks Crutchfield!



    Think twice before buying

    2003 Ford Mustang
    Crutchfield Customer Review (What's this?)

    I have owned this unit for less than a month and I pretty disappointed. Unit freezes constantly. If I start my car 6 times a day, I will probably press the reset button at least 5 times. Once in a while it will start without any issues. No wonder the reset button is right on the front of the stereo for easy access. When the unit is not frozen all the functions work really good. Sorry I cannot give this a better review, but i am tired of having to reset my stereo almost every time I start my car.



    Great for the money, good iPod control!

    Anonymous from Portland, OR on 1/29/2010

    2007 Toyota Tacoma
    Crutchfield Customer Review (What's this?)

    Replaced a factory stereo in a 2007 with iPod connection/control as the main purpose. Good riddance FM transmitter! The iPod control is the best I have seen in any head unit so far - the alphabet search (much like when you cycle rapidly on you iPod) works great and is easy to access. Doesn't take very long to initialize or load data from the iPod. Can't say anything for the bluetooth as I have no interest in using it. The navigation seems to work pretty well and I was able to mount the antenna inside my dash and still get good-enough signal. The sound quality is great and most of the basic features are fairly intuitive (by which I mean I haven't spent much time with the manual). The AVIC Feeds software is a bit awkward but if you know where you want to go it is not hard to transfer the coordinates/address from Google Maps (by means of the send link). Overall I am quite happy - especially for the price! I would give it 5-stars but its just not quite love...



    Quite happy

    Stephen from Ventura, CA on 1/23/2010

    2005 Toyota Matrix
    Crutchfield Customer Review (What's this?)

    When the price for this unit dropped, I was sold. Other products that feature bluetooth, iPod connectivity & GPS are hundreds more. - Yes, the screen is small and you do notice when navigating, but so far the voice commands are dead-on, so I'm not looking at the screen. - iPod controls work well and it's easy to find what I'm looking for. My wife's iPod control on her smaller Pioneer is definitely trickier. - If I make a phone call on my way home, I find myself sitting in the car finish the conversation. It's just nice to be able to talk and not have a headset stuck in my ear or use one arm to hold the cell phone. Sound quality of calls seems good to the folks I am talking to, but may depend on how quiet your car's interior is (I have an '05 Matrix). I can hear the caller just fine. - My entire contact list moved into the unit in 90 seconds; making calls is really easy. - POI's are pretty limited, but you can get street addresses from Goog411 for restaurants, theaters, then plug them into the GPS. - Best of all, the unit made my Polk component speakers sound much more balanced. With the factory stereo, the high frequencies always sounded shrill, but maybe the added power was what the speakers needed. I also added a small Kenwood powered sub. Took a little time getting the sub crossover set in the head unit, the gain dialed in on the sub, and the EQ set to flat, but now: WOW. I can't wait to drive - I'm hearing all these subtleties to the music I haven't noticed before.



    U310BT Exceeds Expectations

    Kevin from Appleton, WI on 1/17/2010

    Crutchfield Customer Review (What's this?)

    Purchased unit and Crutchfield provided good instructions, was pretty easy to install even though it was my first. I like everything about the U310BT but do think the POI's are very limited but that is not a big deal to me. All the controls work well and I really like the BlueTooth. I have read complaint's about it in the reviews but am not sure how it could be much better. It exceeded my expectations. I put the mic up in the drivers side corner of the windshield and it works fine. I am learning the controls yet but I never looked in the manual but so far, I have figured out how to do anything I wanted. I installed this in a Honda Pilot and no longer can use the sub so I will probably get a new one along with an amp. I will say I was a little disappointed in the output of the stereo. It sounds fine but I thought it would have more power. I will eventually need an amp too. I would recommend this unit. I really like how it cleaned up my car being everything is all in one system, no more external satalite radio and navigation system laying around.



    Pioneer AVIC-U310BT

    Michael from Brooklyn, NY on 1/15/2010

    This is the second Pioneer navigation unit I own, and I wonder if the quality is getting worse instead of better. The POI's are limited. When you're cruising down the street, it does not show street names unless you have a destination set. Also, you could have already passed a street, and yet it will show that the street is up ahead. These issues however, are not noticeable when you have a destination set. Furthermore, it's not easy to type addresses in since its so small. You have to type entire street names instead of it assisting you like with other gps units. The only pro is that the sound quality is great.



    Good Feature Set for Price.

    2009 Dodge Ram 1500
    Crutchfield Customer Review (What's this?)

    I wanted to upgrade my 2009 Dodge Ram stock head unit and have GPS, Bluetooth, IPod and Satellite functionality without dropping the budget of a small country into audio equipment for my car. This unit fits the bill perfectly. It's not outstanding but it does everything I wanted and even with the XM tuner and harness it came in less than $600. The GPS screen is small compared to some higher end units but about the same size as portable unit. The AVIC Feeds and iPhone app feature is awsome, iPod control is great, bluetooth is quite good and it sounds suprisingly good even with no amp and factory speakers. Note that while it does say this unit fits a standard 2DIN opening, if you have a 2009+ Dodge Ram, you will need a Dremel and a Hacksaw as Dodge in their infinite wisdom decided their idea of 2DIN and the industry standard should differ. It only requires cutting behind the trim bezel so the finished installation looks perfect. Overall, nice unit, a lot of features in a reasonably priced package. No problem recommending it.



    Meets or exceeds for the price

    Dave from Toms River, NJ on 9/27/2009

    Crutchfield Customer Review (What's this?)

    This unit is perfect for the price, even with some minor "annoying" flaws. The head unit compensates for the HD drop out by allowing the user to turn "blending" on or off. iPhone 3G controls are fully supported when connected to the USB port in the rear. Bluetooth works and sounds great with iPhone 3G, all the contacts will transfer over to the head unit and it pairs up in seconds. I mounted the microphone at the top of the support pillar between the windshield and driver's door, and everyone I called had no complaints about my voice. Also, the keypad is disabled while making a call, so you cannot access voice mail, or anything else that requires a DTMF tone to activate. As previously described, Pioneer's POI's are a joke, only here to force you to spend more money on their update. Many categories are left out, or not featured at all, but cemeteries and toll booths are included. You can detach it and use their website to upload your own POI's. The GPS seems to be about a half a block behind your actual vehicle, but will re-adjust if you turn before your icon reaches that street. Also, the maps are a little dated, roads that have been improved or built within the last 5 years may not be included in the factory installed atlas software. The light green wire prohibits the driver from programming a new destination, or dialing a number directly from the dial pad as the car is moving. You can choose any contact or favorite in the memory though.



    GPS, iPod and Bluetooth-- 2 out 3 ain't bad

    schizmo from Dallas, TX on 9/21/2009

    The AVIC U310BT is supposed to satisfy the holy trinity of car audio-- GPS, Bluetooth and iPod control. 2 out of 3 ain't bad for the price. The GPS is basic but adequate. The lady in the box giving directions has a very slight flutter to her voice but she gets me there just fine. The POIs that are included in the unit are very limited. There is a SD card that adds 12 million POIs. I'm waiting for the price to drop before buying one. The AVIC Feeds software allows you to customize the boot screen, button colors and set destinations on the removable faceplate from your PC via an included cable or SD card. It also has a drive reporting feature that calculates your MPG, CPM, etc. My iPod dream has been a way to navigate through the 100s of artists and 1000s of CDs to play the tune I wanted without killing myself while driving. The U310BT allows me to search with a minimum of clicks and twists to the song I want while driving. However, the confusing menus make reading the manual a necessity to enjoy the full features of this unit. Once you "get" the menu flow, it all makes sense and works well. My biggest disappointment is the Bluetooth, it hangs intermittently. It requires a faceplate reset and then you must re-pair the cell. AVIC has been criticized for slow boot times. The 310BT however comes on instantly because the battery in the removable faceplate keeps it in standby. The instant on function seems to be the culprit that causes bluetooth to hang .



    Missing POI's but worth the money

    crescentfallen from North Plainfield, NJ on 9/17/2009

    2007 Nissan Altima
    Crutchfield Customer Review (What's this?)

    1st off I must say the Crutchfield service was excellent and got my unit in 2 days. Installation was easy on my 07 Altima and the unit started up right away. I have ready other reviews on this item across the web and many people complain about lack of POIs and navigating the menu. I have this unit for 1 day and the menu navigtion was pretty easy it sucks that this unit does'nt come with a remote. I was able to pair up my phone and transfer the contacts withing 2 minutes, the mic worked fine for me it was clear reception. The navigation spoke clearly and the lane assist is a great feature. The directions were very accurate. Being able to change the color of the unit to match my interior was a great plus. This unit sound so much better than my previous Pioneer reciever. So far my only coplaints are the lack of POIs and having to pay for an update. This unit delivers as far as audio and bluetooth but the gps could have been better due to lack of POIs. For the price you are getting a great deal I would definately recommend this unit



    Use less Navigation, un-usable Bluetooth Microphone

    nayudusrini from Redmond, WA on 9/6/2009

    As expected Crutchfield provided car specific detailed instructions, and it made installation very easy. Audio is fine(still need to get used to operation), but navigation seems lagging behind few seconds behind actual position, so you may miss a turn before it showed( no GPS signal issue). Also, sometime, the directions shown on the screen and voice are not matching!!? Contrary to what is mentioned on Crutchfiled about SD card playback, you can not play music from SD card. You can only download POIs, voices, or upload route information. And for POIs, there is no category for restaurants!!? Do you believe they have cementary, but not food!? May be people who buy this unit are looking for easiest way for cremation. And another main issue, Bluetooth. The pairing, dialing everything is fine, but MIC is the worst. I have to talk into the MIC directly very loudly to hear anything on other side. There are no options to adjust the MIC gain anywhere. One main reason I bought this is for bluetooth. It is really disappointing. I would not give up yet. Another issue, You can not use dialpad once you are talking!!? What the heck they are thinking? Many customer service calls, many voicemail systems need us to enter keys to proceed(like checking my home phone voice mail). They claim it is designed by Parrot.. so much for that. Overall, I would not recommend unit at all.<br><br> <b>[Editor's Note: You are correct. You cannot play music from the SD card.

    Display Features

    Illumination Color Adjustment: The color of the button illumination can be set to virtually any color you desire. You can select from 8 preset colors, or choose a continuous scan of the 8 default colors. You can also create a custom color using Pioneer's AVIC Feeds program and load it into the unit using an SD card.


    Navigation Module: The navigation module on the AVIC-U310BT is removable and can be used as a map when detached (although it's not a standalone portable GPS unit).

    Flash Memory Navigation: Pioneer has taken the entire TeleAtlas database, which previously required two DVDs, and compressed it into a 2 GB internal flash memory. The maps cover the entire United States (including Alaska and Hawaii) and Canada. The database provides over 400 thousand points-of-interest (POIs) in various categories throughout the coverage area. With the addition of an optional POI SD card (item number 130SDOPU03), the POI database increases to over 12 million. You can search for a POI near your current location, near your destination, or near a specific city, or you can spell the POI name.

    Positioning Technology: The AVIC-U310BT accurately measures your current location by the Global Positioning System, a network of satellites orbiting the earth to give you time and position information. The accuracy of the GPS information depends upon how good the reception is. The unit has a 20-channel GPS receiver with a magnetic antenna included.

    Voice Guidance/Text to Speech: In addition to graphical on-screen directions and maps, the AVIC-U310BT provides voice guidance and turn-by-turn directions. You can choose English, French, or Spanish guidance. Text-to-speech is available in English, announcing the street names along with the turn directions. Note: The TTS file may be on the supplied CD-ROM and must be copied to the SD memory card.

    AVIC Feeds: You can create custom Points of Interest (POIs) by using the AVIC Feeds utility program, available on the Pioneer website ( Once created, you can store the POI on an SD card and upload the information to the unit. Other AVIC Feeds applications include Driving Report and Picture Editor.

    Audio Section

    CEA2006 Compliant: The power specifications for the AVIC-U310BT 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 AVIC-U310BT are as follows:

    • CEA2006 Specs: 14 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N), 91 dBA S/N (reference: 1 watt into 4 ohms)
    • Continuous Power Output: 22 watts RMS x 4 channels (at 4 ohms, 50Hz-15kHz, 5% THD)
    • Maximum Power Output: 50 watts x 4 channels (or 50 watts x 2 channels at 4 ohms + 70 watts x 1 channel at 2 ohms for subwoofer)

    3-Band Parametric Equalizer: This unit includes a 3-band parametric EQ with selectable Q factor. You can adjust the low frequency (40Hz, 80Hz, 100Hz, or 160Hz), midrange (200kHz, 500kHz, 1kHz, or 2kHz) and high frequency (3.15kHz, 8kHz, 10kHz, or 12.5kHz) from -12dB to +12dB. The Q factor (slope of the boost or cut) may be selected from 0.35, 0.59, 0.95, or 1.15. Selecting a narrow (steep) Q factor results in frequencies around the center frequency being affected less by the boost or cut than they are with a wide Q factor. This feature is useful for taming frequency response problems caused by the dimensions, materials, and speaker locations of a vehicle.

    EQ Presets: There are 6 preset EQ curves: Super Bass, Powerful, Natural, Vocal, Flat, and Custom. The Custom curve allows you to create and store EQ settings in memory. You can create a separate Custom curve for each source.

    Adjustable Loudness: You can select one of three different levels of loudness compensation. A Low loudness contour provides +3.5dB boost at 100Hz and +3dB boost at 10kHz. A Mid boost is +10dB at 100Hz and +6.5dB at 10kHz. A High loudness contour is +11dB at both 100Hz and 10kHz.

    Note: These Loudness contours use a reference volume level of -30dB.

    Source Level Adjustment (SLA): This function lets you adjust the volume level of each source to prevent radical changes in volume when switching between sources. Settings are based on the volume level of the FM tuner, which remains unchanged.

    Advanced Sound Retriever: The Advanced Sound Retriever automatically enhances compressed audio and restores the original richness of the recording. There are two available levels of the Sound Retriever effect.

    High-Pass Filter: When you don't want sound in the subwoofer frequency range output from the front and rear speakers, you can activate the built-in high-pass filter. You may select a filter frequency of 50Hz, 63Hz, 80Hz, 100Hz, or 125Hz with a slope of 12dB per octave. The high-pass filter effects the line and speaker level outputs.

    Rear/Subwoofer Preouts: In addition to the front preamp outputs, a second pair can be used as rear or subwoofer outputs (switchable). When set to subwoofer, the outputs are non-fading, and may be set for normal or reverse phase. The built-in low-pass filter frequency can be set to 50Hz, 63Hz, 80Hz, 100Hz, or 125Hz. The level of the subwoofer output can be adjusted between -24 to +6. The low-pass filter has a slope of 18dB per octave.

    Bass Boost: The Bass Boost function raises the level of low frequency sounds; select the desired level of bass boost between 0 and 6 (Gain: 0dB to +12dB).

    AM/FM Tuner

    Supertuner IIID AM/FM Tuner: The Supertuner IIID features Feed Forward Control, which avoids multi-path interference. This pre-detection of interference enables quick filter control and results in less distortion. In addition, the Supertuner IIID creates enhanced stereo during multi-path interference, unlike conventional tuners that collapse to mono.

    DVD/CD Playback

    Disc Compatibility: The single CD slot is compatible with prerecorded audio CDs, as well as CD-R and CD-RW discs. Recordable discs can contain MP3, WMA, AAC, or WAV files. Discs should be recorded in ISO9660 Level 1 or 2, Romeo, or Joliet. The unit will accept up to 255 folders and 999 files.

    Compressed Audio on CD-R/RW: This unit can play the following types of compressed files recorded on a disc:

    • MP3: bit rates of 8 to 320 kbps (CBR), VBR; incompatible with MP3 Pro, MP3i, or m3u
    • WMA: bit rates of 48 to 384 kbps (CBR), VBR; incompatible with Windows Media Audio 9 Professional, Lossless, and Voice
    • AAC: bit rates of 16 to 320 kbps (CBR only), incompatible with Apple Lossless and files encoded with VBR
    • WAV: LPCM and MS ADPCM formats; LPCM sampling rates 16-48 kHz, MS ADPCM sampling rates 22.05 and 44.1 kHz

    Built-in Bluetooth

    Bluetooth Solution: The AVIC-U310BT is equipped with a built-in Parrot Bluetooth system. You can make and receive phone calls wirelessly through the receiver. When a call is received, the caller ID information appears on screen and you can choose to answer or reject the call. There is also an Auto Answer feature set in the menu. To place a call you can access the on screen number pad, call from call history (dialed, received, and missed), dial a phone book entry, call a POI (if the phone number is in the database), or call home (one your home number is programmed).

    Note: Not all Bluetooth-capable phones are compatible, but Parrot compatibility updates will be available periodically.

    Microphone: The included microphone has a 13' cord that plugs into the back of the radio, and comes with an adjustable visor-mount clip. You'll hear the other party through the vehicle's front speakers.

    Phone Pairing: Up to 3 Bluetooth-compatible cell phones can be registered to this head unit (one connected at a time). If your phone supports the feature, you can transfer your entire phonebook to the head unit at once; up to 400 entries per cellular phone.

    GOOG-411: You can dial the free GOOG-411 business phone listing service with one touch.

    Echo Cancellation: The receiver offers an Echo Cancellation feature to keep phone calls sounding loud and clear.
