Hands-Free Calling and Audio Streaming

Stay safe and obey local hands-free laws with built-in Bluetooth (HFP). Easily pair a Bluetooth enabled phone to the DEH-S31BT without having to go through complicated settings. When a registered Bluetooth device is near the receiver, the auto connection function automatically pairs the two units.

From wireless audio streaming (A2DP profile), hands-free calling, and simple pairing, to audio control and artist, album, and song search (AVRCP profile*), Bluetooth® wireless technology has made life

in the vehicle much more convenient. The DEH-S31BT features Bluetooth Hands Free Profile 1.6 including Wideband Speech capability, which improves the sound quality of phone calls by offering double the frequency bandwidth (when compared to calls without Wideband Speech)**.

*Search functions vary by phone.
**Call quality depends on wireless provider’s support of HFP 1.6.

Android Music Support

Users of Android devices running operating system 4.0 or later can connect and listen to music stored on their device to the DEH-S31BT without the need for an app. The process is made possible using Media Transfer Protocol (MTP). MTP allows the receiver to recognize the Android smartphone as a music storage device. Users can now access music via USB stored on an Android device and operate basic operations like FF, REW, Play, Pause, Random Play, and Repeat. Metadata information such as track, artist, and album name can be displayed.
