Rugged and ready to rock
Sony's MEX-M71BT marine CD receiver offers all the features you want in a new radio, plus the water-resistant toughness you want in a piece of marine electronics. Built-in Bluetooth® and handy front inputs give you plenty of ways to play your tunes, while Sony's EXTRABASS feature ensures that your marine speakers will really get a workout. A conformal-coated circuit board and a UV-resistant front panel ensure that this IPx5-rated receiver will stand up to life on the water.
NFC means ultra-quick pairing
This marine-rated receiver features built-in Bluetooth 4.0 with Simple Secure Pairing, so you can take calls and listen to music (including your favorite Pandora channels) with minimal effort and maximum sound quality. Near Field Communication (NFC) technology means one-touch listening with compatible devices — simply touch the NFC logo with your phone, and you're paired up. It's a very handy feature to have on a boat.
Sony's App Remote gives you voice control for select smartphones, plus you can take advantage of one-touch voice activation for your iPhone® using Bluetooth. You can also plug your iPod®, iPhone, Android™ smartphone, or other compatible device into a USB port and play music while charging the device. Sony's Quick-BrowZer® feature lets you find your music by artist, album, genre, song or playlist. The detachable front display shows song title and artist info, then gives you caller ID info when you get a call.
SiriusXM satellite radio
You can add a SiriusXM satellite radio tuner (not included, requires subscription) to your receiver. Satellite radio offers an unparalleled variety of music, news, sports, and talk, and your favorite channels will stay with you, even when you're miles offshore. No wonder it's a feature more and more boaters want.
Get the sound you want
The MEX-M71BT features a built-in Dynamic Reality Amp that's designed to produce plenty of power without noise or distortion. You can also customize the sound to suit your musical tastes using the built-in 10-band equalizer, selectable low- and high-pass crossovers, and other soundshaping tools. If you're planning on expanding your system in the future, you'll have 3 sets of preamp outputs to work with.
You'll also enjoy plenty of control options with the MEX-M71BT.

Marine Rated: The Sony MEX-M71BT marine-rated (IPX5) CD receiver is ready for the marine environment with a UV resistant coating and coated circuit board. The Sony marine receiver is specifically designed to withstand the ASTM G154 test for UV resistance. This means the faceplate is treated to resist fading and discoloring after prolonged exposure to UV light. The marine receiver uses coated circuit boards which safeguards them from the humid marine environment.
Note: Even though the conformal coating makes the receiver water-resistant, it is still recommended that it be used with a universal marine cover (sold separately - see accessories tab).
Detachable Face w/ Caution Alarm: The Sony MEX-M71BT 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.
High-Contrast LCD: With 5x the contrast of conventional screens, plus an optimized viewing angle, the MEX-M71BT's LCD screen is always easy to read. You can adjust its brightness level from 1-10. You can also set its dimmer to Auto, On, or Off. The Auto mode dims the head unit's display automatically when you turn your vehicle's lights on (illumination wire must be connected).
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. You can select from 15 preset colors or a customized color (R-G-B). You can choose to use the same color for the LCD screen and button illumination, or use a separate color for each one. You can even set the head unit's LCD screen's illumination to pulse with your music.
Auto Scroll: The Auto Scroll feature allows long displayed items to scroll automatically across the display when the track is changed on a disc or device.
Display Illumination/Clock Display: Pressing the SRC/OFF button once will switch sources. Pressing and holding the SRC/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 SRC/OFF button for two seconds.
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 after 30 minutes of the power being turned off to the head unit.
Bluetooth Technology: The Sony MEX-M71BT 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-M71BT.
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. One 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-M71BT without having to enter pin codes or go through complicated settings.

The unit 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.
