You can connect two phones full time via Bluetooth, with secure and simple pairing. Calls to either phone can be received by a push of a key on the head unit. In addition to repeat and random playback of music files, you can also easily search for songs using the browsing function. Just look for and choose the song you want to hear from the folder name and song name lists. HPF 1.6 wideband speech is supported, so you can enjoy hands-free phoning convenience together with higher voice quality and improved noise reduction.
