other music sources, such as an iPod, HD Radio tuner, or CD changer.
Bluetooth Wireless Communication: The MEX-BT2700 has
built-in Bluetooth hardware to integrate with Bluetooth-enabled cellular phones
and audio players, including the Apple iPhone. Bluetooth

allowing you to make and receive cell phone calls, and listen to a Bluetooth
audio device. Up to 8 phones or audio devices can be registered with the MEX-BT2700.
You can adjust the volume for each connected Bluetooth audio device from -8 to

devices, please visit the Sony e-support website (esupport.sony.com).
The MEX-BT2700 supports the following Bluetooth profiles:
- Hands-Free Talk (HFP 1.5/HSP): Incoming
calls can be received through this head unit, and the ring
tone is output from your car speakers. Incoming calls can
be rejected if desired. To make a call from this unit, only
redial is used. To call another phone, you will need to dial
the number on your cell phone, and then transfer the call to
the head unit. 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 BT2700
has a built-in microphone located behind the detachable
faceplate. The MEX-BT2700 also supports Voice Dial Activation
which allows you to activate voice dialing with a compatible
Bluetooth enabled mobile-phone by saying the voice tag stored
in your cellular phone.
- Music Streaming (A2DP/AVRCP): You can listen
to music from an audio device that supports A2DP Bluetooth technology.
Cellular phones that support A2DP and have music stored in its memory
can be played through this head unit. You can listen to and perform
some operations on an audio device that supports AVRCP Bluetooth
technology. On some devices, you can pause and resume playback
and skip tracks by pressing buttons on the head unit.

memory bands to store and receive AM/FM stations. You can store up to 6 presets
