This good-looking car stereo offers great sound, an excellent Bluetooth® feature set, and some pretty sophisticated smartphone integration options.

Your phone's music and more

My smartphone is my "go to" source for messaging, info, and entertainment, so I appreciate a car stereo that works with it intuitively. Plug your iOS device or compatible Android phone into the front USB port for access to all of your favorite music, including FLAC files. You can even use voice commands to send text messages and other tasks with both iOS and Android devices.

Pair and go with Bluetooth

Pairing is easy with Sony's Simple Secure Pairing system, and if your phone supports NFC, you can simply touch it to the receiver to pair the device. Once paired, the MEX-N4200BT's built-in Bluetooth adds a new level of convenience and capability to your car. You can talk hands-free when you get a call, plus you can stream the music stored on your mobile device wirelessly through the receiver.

Sony MEX-N4200BT

The MEX-N4200BT is a stylish addition to your dash.

Look sharp

Sharp styling is on display with this Sony. Carbon fiber accents frame the controls, and when you're getting your groove on, the Sound Synchronization feature pulses the lights to match your music. Details like a nifty sliding USB port cover round out the package.

Stellar audio

Sony's impressive Digital Reality amp delivers solid sound output and realistic audio reproduction. The 10-band EQ and frequency filters give you sound tuning options that will make your speaker setup shine.

Want to keep your steering wheel controls?

This Sony has the ability to retain the steering wheel controls in many Japanese vehicles, but we recommend using a separate SWC adapter. In all other vehicles, you'll need an adapter to retain those controls with this car stereo. Connect a few wires, then program the adapter for your particular car and radio, and you'll retain the convenience of your steering wheel controls. You'll see the adapters that work with your vehicle when you add this receiver to your cart.

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.

iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

Built-in Bluetooth

Bluetooth Technology: The Sony MEX-N4200BT is equipped with built-in Bluetooth (version 3.0), 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 1.6 (Hands Free Profile), PBAB 1.0 (Phone Book Access Profile).
  • Audio Streaming: A2DP 1.3 (Advanced Audio Distribution Profile), AVRCP 1.3 (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 Sony MEX-N4200BT.

Multi-Device Pairing w/ Dual-Phone Connection: Up to nine Bluetooth-compatible devices can be paired to this receiver. You are even able to keep two Bluetooth-enabled phones connected at the same time, so you can make and receive calls from either phone through the head unit. Only one audio device can be connected at a time, which means only one of the two connected phones can stream audio. Once an already paired device is in close proximity to the Sony receiver, the two units will automatically re-connect. The head unit offers three pairing modes - SSP, NFC, & USB Auto

  • Simple Secure Pairing: With Simple Secure Pairing (SSP), you can easily pair a Bluetooth enabled phone to the Sony MEX-N4200BT without having to enter pin codes or go through complicated settings.
  • Near Field Communication (for Android): Android (OS 4.0+) smartphones that have Near Field Communication (NFC) pair simply by touching the Android device's NFC tag to the head unit's NFC tag on its rotary-knob. For older Android smartphones that don't have OS 4.0 or better installed, download the NFC Easy Connect app from Google Play to use the head unit's NFC pairing function.
  • USB Auto (for iPhone): You can pair your Apple iPhone (iOS 5.0+) by simply connecting it to the Sony head unit via USB and activating the Bluetooth function on your Apple device.

Hands-Free Communication w/ Integrated Mic: The Sony MEX-N4200BT supports Bluetooth hands-free communication for your Bluetooth enabled cell-phone (such as your iPhone or Android smartphone). Bluetooth hands-free communication helps to minimize distraction while driving by allowing you to control your mobile phone from the head unit, so you don't have to touch your mobile phone. The unit is equipped with an integrated microphone (featuring adjustable gain) on the front-panel, so you can carry on your side of the conversation while listening to the caller through your vehicles speakers. And thanks to the latest Hands-Free Profile (HFP 1.6) with wideband speech capability, the MEX-N4200BT provides more natural sound quality and details during wireless calls.

  • Answering Calls: Incoming calls can be answered manually or automatically (between 3-10 seconds) through the Sony head unit, while the ring tone is output from your car speakers and the caller's name or phone number is displayed on the head unit's LCD. Incoming calls can also be rejected if desired.
  • Dialing a Number: Using the MEX-N4200BT, you can dial a phone number in one of the following ways.
    • Entering Phone #: Allows you to manually dial a phone number using the unit's control dial.
    • Preset Dial: You can store up to 6 contacts in the preset dial for quick dialing.
    • Phone Book: You can store up to 1,000 contacts in the unit's phone book. Up to a 40 character name can be input for each contact.
    • Call History: The unit will store the last 20 calls, allowing you to select a previous phone number quickly from the list.
    • Voice Dial: You can make a call using the voice tags stored on your connected cellular phone.
    • Redial: Use to easily redial the last number you called.
  • During a conversation, you can switch between the Private Mode (talking directly on your cell phone) and the Hands Free Mode.
  • The unit features a rear-panel 3.5mm microphone jack for adding an external microphone (sold separately).

Wireless Audio Streaming: The Sony MEX-N4200BT supports wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth-enabled smartphone or audio player, plus song/artist information display. You are able to stream your stored music library on your Bluetooth-enabled smartphone, as well as music apps downloaded on your smartphone to the Sony MEX-N4200BT for playback.

  • SBC + AAC Codecs: In addition to support for the standard SBC Bluetooth audio codec, the MEX-N4200BT offers support of AAC.  By supporting AAC, the MEX-N4200BT offers better audio performance of the music streamed from your Apple iPod, iPhone, or iPad.
  • Music Control: The Sony MEX-N4200BT lets you control basic playback functions like Play/Pause and Previous/Next Track from its front-panel. Advanced music browsing is not supported.
  • Song/Artist Information: The head unit will also display your stored music and music app's song information; such as Artist name and Song/Album title (not compatible with all apps).
Note: When an incoming call or outgoing call is in progress from your Bluetooth enabled mobile phone, audio streaming will be paused so you can take your call. Once the call is finished, your streaming music will resume.

Siri Eyes Free Control (for iPhone): When paired and connected to an iPhone with Siri via Bluetooth, the Sony MEX-N4200BT has the ability to access Siri through its front-panel controls and external microphone. Simply activate the "voice dial" function on the MEX-N4200BT to engage Siri and use the built-in microphone to communicate with Siri. Siri's voice will be heard through your vehicle's speakers. All Siri functions including hands-free calling, music search, setting reminders, text-messaging, audible navigation, and more can be done through the head unit and its microphone. You can even ask Siri to get directions to a destination and the turn-by-turn instructions will heard through your vehicle's speakers, while the on-screen map still displays on your iPhone with Siri. The head unit's audio is attenuated while Siri provides audible directions.

Note: The head unit will only display hands-free calling and Bluetooth audio information (all other functions of Siri are only audible through the MEX-N4200BT; visual data will still need to be viewed from your iPhone).

If you make a call or answer a call from your smartphone while listening to music in this mode, the music will pause until you are finished with the call and then start back up again.
  • MTP (Stored Music w/ Song/Artist Info): The MEX-N4200BT also supports MTP for playback & control of stored MP3/WMA music files on your Android (OS 4.0+) device through the Sony receiver's front-panel USB port.

How do I search for my phone's Bluetooth signal?
[ Jcottey  Feb 07, 2020 ]
1 answer
I have a galaxy, and while this should work the same way on other phones, it may be a bit different. First you'll wire everything into the car. Next you turn the car on, its bluetooth will activate automatically (if it doesn't, just cycle through the modes until you hit BT). Now on your phone, open the bluetooth menu, turn it on and hit scan. It will show up as "mex-something". After you pair it the first time, it will auto-pair everytime you get in the car, which is super nice. Hope that helps.

Where does an external microphone connect to the 4200 BT?
[ Vance  Oct 07, 2019 ]

It plugs into the back of the stereo. There is a specific mic input that is easy to spot.
[ Anthony  Oct 18, 2019 ]
this unit has a built in mic. no need for an external
[ Laurie  Oct 18, 2019 ]
I don't think you can connect a wired microphone. You can connect your phone via bluetooth. There is a built in microphone.

If I pair this device via Bluetooth to my smart phone, will I be able to use controls on the head unit to control playback of music on the phone, i.e., Pause, FF, Next Track, etc.? I have a Sony-G1200U and when I connect the smartphone to that via USB, I am able to control the smartphone's music via the controls on the head unit- just like if I'm playing a CD. I bought a 3rd party Bluetooth device that pairs my smart phone to the head unit, but all it will do is stream music to the unit- the playback has to be controlled by the phone itself.

Sorry, I installed this unit in my daughter's car and can't remember if we tried to control the phone from the unit. She is out of the country for a week but I can check with her once she returns if you aren't in a hurry for the answer.
[ Bradley  Feb 17, 2019 ]
Yes you can i always did it with mine...but the mex 5200 is better than 4200... but don't get me wrong the 4200 is nice but there's way more controlling on the 5200 then there is the 42

Does this radio work with spotify? Also, will this radio fit in a 91 Ford bronco Eddie Bauer?
[ KC  Dec 26, 2018 ]

There is no built-in Spotify app on this unit, but it works fine if you connect it to your phone and open Spotify on your phone. When you purchase this on Crutchfield and you specify your vehicle and and model they will give you all the parts that you need to install it on your Bronco.
[ Phil  Dec 27, 2018 ]
Yes it works with Spotify Pandora and YouTube and any other Bluetooth station around and yes it should fit in a 91 Ford Bronco you may need it insulation kit but it will fit

It's a good unit I haven't played with it too much, so I really don't know, Sorry
[ ROBERT G  Jan 24, 2018 ]
I see that the Sony Mex-B4200BT has an intergraded microphone in the front panel. How does the internal microphone compare to external microphone option as far as sound quality? Do you get a better microphone quality if you opt for radio with an external microphone, such as the Sony's Mex-B5200BT model? I ask because I'm looking for a good sound quality microphone when I place a phone call.
[ Bernave  Jan 20, 2018 ]

Generally speaking, external wired microphones tend to offer improved audio quality versus integrated (or built-in) microphones, so you can be heard easier over surrounding traffic and road noise. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!
[ Larry  Jan 24, 2018 ]  Staff
The built-in mic seems to be pretty good, but I sometimes have to speak up for the other party to hear me over the road noise. I have never had an external mic, so I really don't know if it would be that much better. Overall, I am well pleased with the 4200.
[ BG  Jan 24, 2018 ]
does it come with a mic?
[ abel  Nov 20, 2017 ]
1 answer
Yes. The microphone is integrated in the front panel of the stereo. You will find this information, and more, by clicking the "Details" tab on the stereo's main webpage and scrolling down below the "Features & Specs" table. I hope that helps. My Bio:
