Nakamichi's NA250BTR CD receiver combines conventional good looks with today's technology, including Bluetooth® for hands-free calling and wireless audio streaming, a USB port and SD card slot for digital music, and a variable color display that'll add a little flash. You'll also get CD playback and AM/FM radio, if you're into more traditional fare.

Bluetooth means wireless

Bluetooth provides you hands-free calling convenience, plus a wireless connection to the songs stored on your compatible smartphone. A sensitive Bluetooth microphone, built into the receiver's faceplate, picks up your end of the conversation.

Many ways to play your music

On the front panel, you'll find a USB port for plugging in a thumb drive full of music and a mini-jack plug for portable audio players. An SD card slot is tucked behind the detachable faceplate for even more digital music. The included CD player also includes electronic shock protection (ESP) for playing tunes on bumpier roads, while the AM/FM tuner includes the Radio Data System (RDS) enabling you to see station information on the receiver's display.

Round out the experience

Nakamichi includes a variable color display on the NA250BTR so you can customize the look of the radio in your dash. They also provide five hot 5-volt preamp outputs for adding outboard amps for your speakers and subwoofer. The NA250BTR lets you refine your music with a 3-band parametric equalizer that lets you pick the centerpoint for your bass, midrange, and treble controls.

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.

    Very nice unit for the money seems easy to use and friendly unit while driving

    Pros: slim design and very user friendly also easy to install but good quality

    Cons: display colors change to often and detachable face hard to remove in a hurry

    NA250BTR- Great value!

    2003 Audi TT
    Crutchfield Customer Review (What's this?)

    I finally made time to install the unit in the dash of my Audi TT- I was tired of the stock "Bose" stereo (made by Panasonic). The kit that Crutchfield put together for me had everything needed except for a faceplate/bezel... Install went smoothly, The unit fit the dash perfectly, and is a definite improvement over the factory stock unit. I keep an SDRAM card plugged into the socket, but also stream music without any issues. The hands free car phone feature works very well also. Highly recommended, great sound & "big bang for your buck"!

    Pros: Nice feature-set, less whiz-bang nonsense built in, great sound!

    Cons: Can't connect to the dash lights dimmer in the car, not enough documentation about how much SD memory it will handle (seems to only accept 999 songs and/or 85 folders on the SDRAM card). I have a feeling that there may be other settings and features that aren't documented.......

    1996 Saab 9000
    Crutchfield Customer Review (What's this?)

    I think I got a defective unit; it was an open-box deal that, in retrospect, cost me a lot more in time and trouble than the money I saved. Thank goodness for Crutchfield's solid-gold customer service! I installed this unit in my 1996 Saab 9000 to leverage the factory Nokia amp - it has a good reputation and is paid for ;-) . I always use solder/shrink sleeving in all my installations. My kit included the Scoche SLC4 LOC (line output converter). I soldered good-quality RCA connectors to my amp's line-level inputs to take advantage of the HU's 5V line-level outputs. I was attracted by its simple appearance (no Vegas display for me!) and its no-frills features. This Saab story starts out with the DIN installation kit not fitting my factory harness - snip, snip, snip... I connected everything according to the provided instructions (easy). The LOC provided mixed results - I ended up ditching it in favor of better audio quality. Using the HU proved disappointing: the built-in microphone did not seem to work for calls, the unit froze, requiring me to detach the faceplate to reset it, and the tuner is very weak (the seek feature picked up all kinds of air noise). The preset tuner buttons are difficult to differentiate by feel and the volume control feels flimsy. My son's iPhone would not pair with BT, but my Galaxy S4/Lollipop phone did so effortlessly. The glossy display was difficult to see in daylight; Whenever I made a settings change, I was forced to wait for the animation.

    Pros: Clean design 5V line-level outputs Separate subwoofer line-level output

    Cons: HU freezes - I have to detach faceplate to reset Tuner's signal-pulling power is weak, does not differentiate noise from station signal well Picking up ground loop noise that proper basic grounding cannot solve completely Built-in microphone is worthless, volume control feels a bit flimsy Glossy display difficult to see in daylight, no auto-dimmer Annoying animation makes you wait whenever you make a change to settings Manual lacks depth Antenna deploys whenever unit is on (not just for t

    Bluetooth Technology: The Nakamichi NA250BTR CD receiver is equipped with built-in Bluetooth (2.0+EDR) allowing you to make and receive phone calls wirelessly through the receiver; as well as stream music wirelessly from your smartphone to the head unit. In order to use Bluetooth wireless technology, your phone must also be Bluetooth compatible and be able to interpret certain profiles. This unit is compatible with the following Bluetooth Profiles:

    • Hands-Free Communication: HFP (Hands Free Profile)
    • Audio Streaming: A2DP (Advanced Audio Distribution Profile), AVRCP (Audio/Video Remote Control Profile)
    Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Nakamichi NA250BTR.

    Hands-Free Communication (w/ Integrated Mic): The Nakamichi NA250BTR allows for wireless communication between the head unit and your Bluetooth-enabled iPhone, Android smartphone, or other Bluetooth compatible mobile phone. You'll be able to answer incoming calls, as well as redial outgoing calls.

    • Answer/End Incoming Call: When there is an incoming call, the current audio source is muted and a ring tone is played via the loudspeakers of the car sound system. The head unit's display will indicate the phone number or display "Phone In" if there is no phone number. You can answer the incoming call from the head unit's front-panel controls. You'll be able to speak into the head unit's integrated mic on the front-panel during your phone conversation, while the other party is heard through your vehicle's speakers.
    • Dialing Outgoing Call: You can easily redial the last number called from the head unit's front-panel controls. All other dialing functions (like phone number, phone book, voice, etc) will have to be done from your Bluetooth-enabled mobile phone first and then transferred to the head unit.
    Note: you can transfer the voice from your vehicle speakers to your mobile phone during a call for more privacy.

    Wireless Audio Streaming: The Nakamichi NA250BTR allows you to wirelessly play back stored music and music apps from your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, or other Bluetooth-enabled devices using a Bluetooth A2DP/AVRCP connection. You can control basic playback functions of your music on your Bluetooth-enabled device from the NA250BTR's front-panel. Playback functions include Play/Pause and Previous/Next Track.

    Note: This unit does not display song/artist information from Bluetooth audio devices, instead it will display "BT Audio".

    Multimedia Playback

    Disc Player w/ ESP: The Nakamichi NA250BTR CD receiver features a single disc player that will playback CD-Audio and finalized CD-R/CD-RW audio discs. The CD receiver offers ESP (electronic shock protection) to prevent your discs from skipping.

    SD Card Slot: The NA250BTR CD receiver features an SD-card slot located behind its detachable front-panel. The SD-card slot supports SD and SDHC memory cards with MP3/WMA music files. The unit's face-plate must be detached to insert or eject an SD/SDHC memory card.

    Front-Panel USB Port: The Nakamichi NA250BTR features a front panel USB (type-A) port that is hidden behind a flip-up cover. The USB port enables connection and control of a portable USB mass-storage class (MSC) device; such as select Android smartphones (Froyo/Gingerbread only), portable digital audio players, or USB thumbdrives. The unit supports playback & control of MP3/WMA music files loaded onto a compatible USB MSC device. USB portable devices that can be charged via USB will be charged when plugged into the CD receiver's USB port (max. 0.5A), and the vehicle's ignition switch is set to ACC or On.

    Note: The head unit's USB port does not support the Apple iPod, iPhone, or iPad.

    MP3/WMA Playback: The Nakamichi CD receiver supports the following types of MP3 and WMA music files recorded onto CD-R/RW disc or loaded onto a USB mass storage class device.

    Off Insert/Eject + Auto Reload: A disc can be inserted or ejected with the power off. When a disc is inserted with the power off, the unit will automatically power up and begin playback. If the ejected disc is not removed within 10 seconds, the disc is automatically inserted again into the loading slot to protect it from dust.

    Aux Input: A front-panel stereo minijack is provided to allow the connection of almost any portable audio source with a 3.5mm headphone output (great for those non-Apple devices). Simply connect your portable digital music player to the unit's front-panel auxiliary input, and you can listen to the audio from the portable player through the speakers in your mobile audio system.

    It is RDS capable. Google the manual and look at page 8. [ William  Jun 09, 2015 ]
    As the FM channel name and information about what's playing are displayed, I guess that the radio does support RDS after all. [ serban  Jun 08, 2015 ]
    It does have RDS. Unfortunately there's only one local FM station which I listen to that offers the info, but it does display in a scrolling pattern. [ CURTIS  Jun 08, 2015 ]
    It does NOT! I bought one and ended up returning it for two reasons, the RDS did not work here in the US and the audio quality of the Bluetooth while making calls was terrible. The internal microphone doesn't work well at all. I exchanged it for a Kenwood Excelon KDC-X599. It works great, much better than the Nak. Call quality is amazing and the rest of the features work AS Advertized. Oh, and you'll save yourself 30 bucks. [ Robert  Jun 08, 2015 ]
