    Built-in Bluetooth

    Bluetooth Technology: The Sony MEX-BT4100P is equipped with built-in Bluetooth (version 2.1 + 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 1.5 (Hands Free Profile), PBAB 1.0 (Phone Book Access Profile).
    • Audio Streaming: A2DP 1.2 (Advanced Audio Distribution Profile), AVRCP 1.3 (Audio/Video Remote Control Profile).

    Pairing: Up to 9 phones or audio devices can be registered with the MEX-BT4100P (only one device can be used at a time). The unit can be set to automatically reconnect to the last connected Bluetooth device when the ignition is turned on. 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-BT4100P.  Please visit Sony eSupport for a complete list of compatible Bluetooth enabled phones.

    External Microphone: The MEX-BT4100P includes an external microphone to carry on your side of your phone conversation and voice command dialing. The external wired microphone offers improved audio quality versus an integrated microphone, so you can be heard easier over noisy traffic and road noise. You can adjust the level of the microphone without affecting the other sources. The external microphone features an attached 12' cable terminated by a right-angle 3.5mm connector which plugs into the mic input on the rear-panel of the head unit. The microphone comes with a mounting bracket which can be clipped to your vehicle's sun-visor or taped to your dash. The external microphone measures 0.465" (diameter) x 1.425" (depth). There is no integrated front-panel mic.

    Hands-Free Communication: The Sony MEX-BT4100P supports Bluetooth hands-free communication for your Bluetooth enabled cell-phone. 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 controls of the MEX-BT4100P can be used to dial a number, answer an in-coming call, or end a call. The unit also features an external microphone (featuring adjustable gain), so you can carry on your side of the conversation while listening to the caller through your vehicles speakers. During a conversation, you can switch between the Private Mode (talking directly on your cell phone) and the Hands Free Mode. 

    • 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-BT4100P, 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.
      • Redial: Use to easily redial the last number you called.
      • 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.

    SMS Indicator: The SMS indicator informs you of any incoming or unread SMS messages on your paired Bluetooth-enabled smartphone. You will still need to view the text message from your phone, as well as create and send text messages from your phone.

    Wireless Audio Streaming (with Meta Data Display): The Sony MEX-BT4100P also supports wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth enabled audio player or smartphone. The MEX-BT4100P will be able to control your stored music's basic playback functions; such as Play/Pause, Previous/Next Track, Fast-Forward/Reverse, and Shuffle/Repeat. The head unit will also display your stored music's song information; such as Artist name, Song title, and Album label. The MEX-BT4100P also supports audio streaming of music apps, but without control or metadata. You will continue to use your Bluetooth enabled smartphone to view and control streaming music apps. 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 Digital Assistant Control: When paired and connected with an iPhone 4S or 5/5C/5S via Bluetooth (not USB), the Sony MEX-BT4100P has the ability to access Siri through its front-panel control and external microphone. Simply activate the "voice dial" function on the MEX-BT4100P to engage Siri and use the included microphone to communicate with Siri. Siri's voice will 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. The head unit will only display hands-free calling and Bluetooth audio information (all other functions of Siri are only audible through the MEX-BT4100P ; visual data will still need to be viewed from your iPhone device).

    Note: You can 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 4S/5/5C/5S. The head unit's audio is attenuated while Siri provides audible directions.

    USB/iPod/Aux Integration

You can search within a specific Quick-BrowZer category or All tracks alphabetically (A-Z).

    Audio Section

    Dynamic Reality Amp: The MEX-BT4100P is equipped with Sony's Dynamic Reality Amp to produce 3-dimensional sound staging for more realistic sound inside your vehicle.

    CEA2006 Compliant Amplifier: The power specifications for the Sony MEX-BT4100P 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 MEX-BT4100P are as follows:

    • Continuous Power Output: 17 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Peak Power Output: 52 watts x 4-channels (208 total watts)

    2V/6Ch Preamp Outputs: The Sony MEX-BT4100P is equipped with 2-volt Front, Rear, & Sub pre-amp outputs giving you the ability to connect external amplifiers to your car stereo system.

    Subwoofer Controls: The unit's subwoofer preamp output is non-fading. The subwoofer preamp output features a low pass filter with a selectable cut-off frequency of 50Hz, 60Hz, 80Hz, 100Hz, 120Hz, or Off. You can also adjust the slope (1/2/3) of the low-pass crossover. You can even adjust the subwoofer preamp output's volume level independently from the head unit's volume control from -10 to +10 in 1dB increments. In addition, you can select the phase of the subwoofer output from Normal or Reverse.

    Subwoofer Direct Connection: You can connect a subwoofer to this head unit without the need of a separate power amplifier. Simply connect a single subwoofer (4-8 ohm) directly to head unit's left or right rear speaker leads (but not both). Same subwoofer controls apply.

    High-Pass Filter: The front & rear speaker outputs offer a selectable high-pass crossover frequency of 50Hz, 60Hz, 80Hz, 100Hz, 120Hz, or Off. You can also adjust the slope (1/2/3) of the high-pass crossover.

    Advanced Sound Engine: Sony's Advanced Sound Engine creates an ideal in-car sound field with digital signal processing. Advanced Sound Engine contains the following features: EQ7, Listening Position, DM+ Advanced, Rear Bass Enhancer, & Dynamic Loudness.

    • EQ7: You can select an equalizer curve from eight music types - Xplod, Vocal, Edge, Cruise, Space, Gravity, Custom, or Off (Flat). The Custom EQ7 mode allows  you to make  your own equalizer settings. You can adjust the level (+/-6dB) of seven different frequency bands - Band1 (63Hz), Band2 (160Hz), Band3 (400Hz), Band4 (1kHz), Band5 (2.5khz), Band6 (6.3khz), and Band7 (16.0kHz).
    • Listening Position: This unit can change the localization of sound by delaying the sound output from each speaker to suit your position, and simulate a natural sound field with the feeling of being in the center of it wherever you sit in the car. You can choose from Front Right, Front Left, Front Center, or Off. You can also set the subwoofer distance of the subwoofer to Near, Normal, or Far
    • RBE (Rear Bass Enhancer): RBE enhances the bass sound by applying the low-pass filter setting to the rear speakers. This function allows the rear speakers to work as a subwoofer even if there is no subwoofer connected.
    • Dynamic Loudness: Dynamic Loudness refers to compensating for volume level & signal gain.
    • DM+ Advanced: DM+ Advanced improves digitally compressed sound by restoring high frequencies lost in the compression process (works only for USB).

    Automatic Level Optimizer: Automatic Level Optimizer analyzes each track's playback level & adjusts the output level to optimize transitions between tracks & sources.

    Beep Tone: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

    Display Features

    Detachable Face w/ Caution Alarm: The Sony MEX-BT4100P features a detachable face for theft prevention. If you turn the ignition switch to the Off position without detaching the head unit's front-panel, the caution alarm will sound for a few seconds. The alarm will only sound if the unit's built-in amplifier is used. No face case is included with this unit. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit. A face-fixing screw is supplied for making the face non-detachable, if desired.

    Dynamic Color Illuminator (35,000 colors): Dynamic Color Illuminator lets you match the head unit's LCD & button illumination to complement your existing vehicle lighting components. With selectable Sound Synchronization, the timing of the color change is synchronized with the audio source. You can select from 12 preset colors (red/amber/m-amber/yellow/white/light green/green/light blue/sky blue/blue/purple/pink), customized color, & 5 preset patterns (rainbow/ocean/sunset/forest/random). The unit's Dynamic Color Illuminator offers the following advance features.

    • Day/Night Color Mode: You can register a customize color for the unit's display and buttons for day & night time driving.
    • Sound Synchronization: The color changes according to synchronization of playing music. When you select a preset pattern sound synchronization becomes effective.
    • White Menu: You can display the menu more clearly (White text) without concern for the unit's other color settings.
    • Start White: When you power-on the head unit, the color of the unit's display and buttons turn white and then the color changes to your chosen customize color. You can enjoy this effect whenever the source is turned on.

    Motion Display: This feature shows moving patterns and a spectrum analyzer on the display when turned on.

    Auto Scroll: This feature allows long displayed items to scroll automatically across the display when the track is changed on a disc.

    Display Illumination/Clock Display: Pressing the Source/Off button once will switch sources. Pressing and holding the Source/Off button for one second will turn off audio output, but the clock display and button illumination remain on. To turn the unit off completely, you must press and hold the Source/Off button for two seconds.

    Dimmer: To change the brightness of the display you can set the MEX-BT4100P to one of three dimmer modes; Dimmer Auto (dims the display automatically when you turn your vehicle's lights on), Dimmer Off (deactivates the dimmer), and Dimmer On (display always dim).

    Auto Off: When installing in a vehicle without an accessory power wire at the radio location, you can set the unit to turn off all lighting a set amount of time after you turn the power off. The Auto Off feature can be set to 30 seconds, 30 minutes, 60 minutes, or No.

    Demo Mode: The head unit's demo mode can be turned On or Off.

    Remote Control

    Wireless Remote Control: The head unit comes supplied with an IR wireless remote control (RM-X231) for easy operation. The included wireless remote allows you to control the basic functions (not Bluetooth) of the Sony head unit while keeping your eyes on the road.

    Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input on the rear of the unit that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.

    Will I be required to by a separate mic to talk using Bluetooth? I would assume the sound from the other end comes through the speakers.

    The mic is included with the radio. A separate purchase isn't needed.
    [ JUSTIN  Jan 16, 2014 ]
    The unit includes a wired microphone with a 12 foot cord. The microphone has a clip so you can put it on the visor or stick it on with the included adhesive pad. You are correct the incoming sound comes through your front speakers. I have had very good luck with my unit. The sound is very clear on both ends.
    [ CHAD A  Jan 16, 2014 ]
    No, the mic is included with the receiver. And you are correct about the sound coming through the speakers.

    I actually don't use the Bluetooth feature on this, but I would expect some form of mic, likely wireless, would be necessary to sync up with this device for 2-way communcation. Good Luck- -Eric
    [ ERIC  Jan 16, 2014 ]
    It does come with a mic. The wire is pretty long, so I was able to run the mic up to my visor. You are correct that it gets "played" through the speakers. Even with the top down I can hear them and they can hear me. I have to say I love this stereo and for the price you cant beat it.
    [ REO  Jan 16, 2014 ]
    This stereo comes with the mic...just plug it in, run the wire and mount it.
    [ Neil  Jan 16, 2014 ]
    Does it show the time of day in the display when it is turned off? Probably a strange question, but I bought a unit that doesn't. At night, it's just this black hole in the middle of the dash. For me, it's very handy just to glance down at the display and see what time it is.
    [ Warren  Jan 11, 2014 ]

    When you power the unit off, press and hold the 'Source' button for only about a second. That should shut off power to the "works", but not completely shut down the unit, so the time display should be visible. (If you hold the button longer, the power will be completely shut off.) If you have trouble with this method, there's a more crude, but equally effective way to get the time to show up. Pop the unit loose from the mount and then push it back in. Until you push the 'Source' button again, you should have the time on-screen but nothing playing.
    [ TOM  Jan 22, 2014 ]
    When the radio is off, yes. with the vehicle off, no.
    [ KEVIN  Jan 12, 2014 ]
    Yes. I just verified that when the key is on and the radio is off/standby.. the clock does indeed continue to display.
    [ MICHAEL  Jan 12, 2014 ]
    Yes it does show the time when turned off.
    [ DAVID  Jan 12, 2014 ]

    Can you stream music via Bluetooth without having to connecting it to voice calls?
    [ Griffin  Jan 09, 2014 ]

    Yes - you can definitely stream music via Bluetooth. One of the 'Source' menu options is "BT Audio". Instructions in the owner's manual online at Crutchfield start around page 22.
    [ TOM  Jan 22, 2014 ]
    I think your phone can determine what sort of services it can provide to the stereo when youre pairing it.

    [ katex  Dec 28, 2013 ]
    8 answers
    I noticed this also, but it depends on if you are going to have just normal car speakers or if you are going to add subwoofers. It did great for my speakers, but I went ahead and added an extra amplifier for my subs.
    [ HUNTER S  Dec 30, 2013 ]
    [ ALAN  Dec 30, 2013 ]
    It does not Require an outboard amp if you are satisfied with the output level of the head unit through the speakers you have. If you are looki g to drive more or larger speakers the. You might want to co wider an amp. I am perfectly happy with the output of my radio through stock speakers
    [ JEFF E  Dec 29, 2013 ]
    Yes, the one built in is just strong enough to give you a bit more kick to the speakers, but it's nothing strong. A separate AMP will be way more effective. The radio itself is beautiful at night, the easy 1 press button then spin of the wheel to search through your songs on USB, AUX, or CD while the song you're listening to continues to play is just wonderful, and the customization plus a well lit display makes it easy to find what you're looking for until you get further acquainted with it. Only thing I could wish for more is if it had some kind of anti-sun glare screen. On the plus side, if you do get a separate AMP with it, the built in AMP will actually continue to work alongside the standalone AMP. With my Pioneer speakers and AMP, I've found that it makes the lower bass hit a bit stronger than usual.
    [ MATT A  Dec 29, 2013 ]

    You shouldn't need one. We installed this in a 2005 Scion tC using the harnesses provided by Crutchfield and the unit is loud just using the factory speaker setup.
    [ CHRISTOPHER  Dec 28, 2013 ]
    I don't believe so, but it is suggested. The built-in amp is only rated at 17 watts, which isn't very powerful, so I suggest you get an amplifier. Especially if you're running powerful speakers. I personally have mine going through an external amp.
