Old school meets new school
Old school meets new school
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.

- 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.
