Simple & cheap solution for music streaming from your phone to your cars stereo system. If your radio supports USB media playback, you can use this device to stream music & voice guidance (and other system sounds) to your car over #bluetooth.
This device receives your phones audio stream and creates fake MP3 files that contain those sounds. Thanks to that you can play wireless music from your phone using standard USB connection.
The device also supports not only #A2DP but also HFP for hands-free calls but the audio delay is so big that this feature is nearly inoperable.
