It also includes a built-in FM radio with RDS, which displays the name of the currently playing song (when tuned to compatible radio stations).

This phone provides Bluetooth version 2.0 wireless connectivity with EDR (enhanced data rate), and includes profiles for communication headset, handsfree car kits, and audio/video remote control. With the A2DP Bluetooth profile, you can stream your music to a pair of compatible Bluetooth stereo headphones.
