    Features

    Overview: The Sony MEX-BT3700U single CD receiver is equipped with Bluetooth technology, offering hands-free calling as well as music streaming from a compatible Bluetooth phone or music player. In addition, you can connect other music sources, such as an iPod, HD or Satellite Radio tuner, or CD changer.

    CEA2006 Compliant: The power specifications for the MEX-BT3700 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-BT3700 are as follows:

    • CEA2006 Specs: 17 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Maximum Power Output: 52 watts x 4 channels (208 watts total)

    AM/FM Tuner: The MEX-BT3700U features a built-in AM/FM digital tuner. The built-in AM/FM tuner offers the following features: Auto/Manual tuning, Preset tuning (6 presets each in 5 bands), Best Tuning Memory, Local Seek Mode, and Mono Mode.

    Disc Compatibility: The CD receiver will play CDs, CD-Rs, and CD-RW discs. The head unit also supports CD Text. The receiver will also play MP3, WMA, and AAC files stored on a CD-R or CD-RW. The headunit can recognize up to 150 folders and 300 folders and files combined. The unit also displays ID3-Tag information up to 32 characters.

    Quick-BrowZer: The unit's Quick-BrowZer feature allow you to search for a track on a CD or USB player/memory. When there are many items in one category, you can search for the desired track quickly by using the Jump function which skips in steps of 10% of the total tracks listed in the current folder.

    Note: When entering the Quick-BrowZer mode, the repeat/shuffle setting is canceled.

    Zappin': You can search for a track on a CD or USB player/memory through the Zappin' feature. When the Zappin' feature is engaged, the unit will play a short sample of the track (about 1 minute into the track), then skip to the next track. You can select the length of the sample: 6 seconds, 9 seconds, or 30 seconds.

    Front Panel Auxiliary Input: A front panel stereo 3.5mm mini-jack is provided to allow the connection of a portable audio source. Just connect your portable cassette, MD or MP3 player to this unit, and you can listen to the audio from the portable player through the speakers in your mobile audio system. The volume level of the auxiliary input is adjustable from -8 to +18 dB to compensate for any difference between the unit and your portable device. The aux input can be deactivated in the menu so it doesn't appear as an available source.

    EQ3 Stage 2: EQ3 Stage 2 offers 7 EQ presets, each of which has a preset value for 3 bands: Low (60Hz), Middle (1kHz), and High (10kHz). The EQ presets and the band values are as follows:

    • Xplod: Low: +6, Middle: +0, High: +2
    • Vocal: Low: +2, Middle: +6, High: +0
    • Edge: Low: +4, Middle: -2, High: +5
    • Cruise: Low: +2, Middle: +0, High: +1
    • Space: Low: +2, Middle: +3, High: +6
    • Gravity: Low: +6, Middle: 0, High: +2
    • Off (flat): Low: 0, Middle: 0, High: 0
    • Custom: Adjustable -10dB to +10dB for each band (Low, Middle, High)

    Loudness: This feature allows you to listen to your music clearly at low volume levels by reinforcing the bass and treble. The bass level is increased to +4 dB at 100 Hz while the treble level is increased to +2 dB a 10 kHz.

    Preamp Outputs: The MEX-BT3700U contains three pairs of RCA preamp outputs - a front pair, rear pair, and subwoofer (non-fading) pair. The Subwoofer output has an adjustable low-pass filter with a selectable cut-off frequency of 160Hz, 140Hz, 120Hz, 100Hz, 80Hz, or Off. You can also adjust the subwoofer's output phase to Normal or Reverse. In addition, you can adjust the subwoofer preamp output's volume level independently from the head unit's volume control from -10 to +10 in 1dB increments.

    High Pass Filter: The BT3700U has a high pass filter for the front and rear preamp and speaker outputs, with a selectable cutoff frequency of 80Hz, 100Hz, 120Hz, 140Hz, or 160Hz.

    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 Off button once will turn off audio output, but the clock display and button illumination remain on. This makes the clock display and face/button illumination "Keyed" instead of "Unit On" only. To turn the unit off completely, you must press the Off button for two seconds.

    Dimmer: To change the brightness of the display you can set the MEX-BT3700U to one of two dimmer modes - Dimmer Off (deactivates the dimmer) or 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.

    Eject: The CD disc can be ejected with the power off. The CD player will automatically reinsert the disc if it's ejected but not removed for 15 seconds or more.

    45-Degree Installation: For flexibility of installation, this unit can be mounted between 0 (horizontal) and 45 degrees.

    Remote Control: The MEX-BT3700U comes with the RM-X304 wireless remote commander for operating the basic audio functions of this unit, as well as the Bluetooth Communication functions. Dimensions: Width = 1.667", Height = 3.938", Depth = 0.443".

    Optional Wired Remote Control: This unit also has a 3.5mm minijack input for the optional RM-X4S wired rotary commander. In addition, the PAC SWI-PS steering wheel remote interface is compatible with this head unit. The SWI-PS interface allows you to retain the use of your steering wheel and/or rear seat radio controls when replacing the factory head unit in select vehicles with a Sony head unit with wired remote capability. In some GM vehicles, this adapter allows you to retain heater control buttons as well.

    External Device Controls

    Bluetooth Wireless Communication: The MEX-BT3700U has built-in Bluetooth hardware to integrate with Bluetooth-enabled cellular phones and audio players.

Up to 8 phones or audio devices can be registered with the MEX-BT3700U. You can adjust the volume for each connected Bluetooth audio device from -8 to +18dB.

The unit can be set to automatically reconnect to the last connected Bluetooth device when the ignition is turned on. The phone rings, and you hear the caller's voice through the front speakers (left, right, or both). The BT3700U has a built-in microphone located behind the detachable faceplate or your can purchase an external microphone (158XAMC10, sold separately) for added clarity.

This is the same cable that comes with the iPod (Type A USB-to-iPod dock connector), or can be purchased separately (472USBCABL). In Audio Mode, the iPod is controlled by the head unit. You can switch the head unit to Passenger Mode and control the iPod directly using the iPod's controls. The receiver is compatible with the following iPods:

    Note: A subscription is also required to receive satellite radio programming from SIRIUS or XM.

    Changer Controls: This unit is compatible with Sony UniLink CD/MP3 and MD changers. In addition, this unit can control compatible Sony Mobile Memory Stick players. A maximum of 5 CD changers, 5 CD/MP3 changers, or 5 MD changers may be connected to this receiver.
