FM Transmitter Hands-free Calling Used for about six months. I am a non-smoker, so it's in clean condition. There is some slight wear and tear, but it's still usable. The double-sided tape for dashboard mounting is also unused. Evolved with "four USB ports and rapid charging QC3.0 Quick Charge support," "various mounting methods like clamping or placing," and "360° rotation," while retaining the original features such as "Japanese language settings," "AUX-IN/OUT compatibility," "music sound and backlight time adjustment," "cycle mode/song title display and music folder selection/deletion," and "Siri/Google voice assistant." ■High-quality sound, hands-free calling, navigation broadcast, car voltage detection, volume adjustment, automatic Bluetooth connection, wired/Bluetooth/microSD/U-disk music playback, Walkman/iPod music playback, automatic power-off memory function, Japanese frequency support.
