Sony MEX-M72BT reviews
This radio is better than I thought. It was difficult to install, but that was because of the old radio I was taking out.
Pros: 2 phones can be connected to the bluetooth at once. Microphone picks up great in my Jeep Wrangler.

Seems to be working out. Unfortunately, it takes so long to adjust the EQ and other adjustments. Installed on my Harley and needed an ad on so the stereo would work with my control buttons...not so impressed.

I installed this unit in my trawler boat. I chose it because it works with a wired remote which I use from the bridge. By plugging in my Ipod to the radio, I can control all the functions of the Ipod fro the bridge.
Cons: I thought the Bluetooth range would be greater

Marine Rated: The Sony MEX-M72BT 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/D4329 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-M72BT 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-M72BT's LCD screen is always easy to read. You can adjust its brightness level from 1-10.

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.
