Our take on the Sony MEX-BT3100P by Crutchfield's Ken Nail
Control your Sony receiver with your smartphone
Sony's MEX-BT3100P CD receiver makes it easier than ever to use a smartphone in your car. Its App Remote feature lets you launch smartphone apps from the receiver, while your smartphone acts as a remote control and a second display for apps and song info. Plus, the MEX-BT3100P will read incoming text messages on your Android phone aloud, so you can stay in the loop while keeping your eyes on the road.
Connecting your smartphone is easy — just plug your iPhone® into the USB input, or set up a Bluetooth® link with your Android™ to get started. Then use your phone's touchscreen to do things like selecting sources, picking radio stations, and launching apps. And on the other side of the App Remote's two-way street, you can select apps using the stereo's source button, the same way you'd choose the CD player or radio as your source.
Hands-free calling is a given with this receiver, but you'll enjoy wireless audio streaming from your mobile devices, too. And if you're a Pandora® Internet radio fan, you can control your stations from the receiver, plus give "thumbs up" and "thumbs down" ratings.
Serious sonic controls
Whether your music's on a smartphone, an iPod®, or CDs, the MEX-BT3100P has the chops to make it sound great. Sony's Dynamic Reality Amp kicks out realistic sound with excellent depth of field and soundstaging, and you can tweak it to match your car with a variety of tools, including a 7-band equalizer and digital time alignment. The two sets of preamp outputs come in handy when you expand the system with external amps or powered subs.
Want to keep your steering wheel controls?
In most vehicles, you can use an adapter (not included) to connect your vehicle's steering wheel controls to this Sony stereo. Connect a few wires, then program the adapter for your particular car and the receiver, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.
Note: Bluetooth compatibility of this device may vary, depending on your phone and service provider.
Note: If you're going to use your iPod with this receiver, be sure to check "Details" for specific iPod model compatibility with this receiver or its optional iPod adapter.
I love the fact that this radio does so much stuff. It can be a little complicated to use at times if you use all the possible connections. But overall a good radio. You cant even find a radio like this for the price I paid any more.

Please visit Sony eSupport for a complete list of compatible Bluetooth enabled phones.
External Microphone: The MEX-BT3100P includes an external microphone to carry on your side of your phone conversation and voice command dialing.

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-BT3100P supports Bluetooth hands-free communication for your Bluetooth enabled cell-phone.

1 question already asked
Thanks for your question David. To be able to use the factory steering wheel controls an adapter is needed. The radio will work without the adapter, but the steering wheel controls for it will not. [ Jeff Nov 13, 2013 ] Staff
