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 AVH-521EX without having to go through complicated settings. When a registered Bluetooth device is in proximity to the receiver, the auto connection function automatically pairs the two units.
From hands-free calling, wireless audio streaming (A2DP) with artist, album, and song search*, simple pairing, and control audio (AVRCP profile), Bluetooth® wireless technology has made life in the vehicle much more convenient.
The AVH-521EX with Bluetooth also includes superior call quality reception using Wideband Speech Handsfree Profile 1.6. Wideband Speech nearly doubles the bandwidth of frequencies of a normal Bluetooth call (when compared to calls without Wideband Speech)**.
Other features include the ability to browse music libraries on smartphones wirelessly.
*Search functions vary by phone.
**Call quality depends on wireless provider’s support of HFP 1.6.
