Use the QC3.0 USB port to fast charge compatible devices while using the unit. For hands-free calls, answer through the car audio system; the built-in microphone handles voice with noise suppression and echo cancellation.

Recommendations

For best audio quality, select a clear FM frequency with minimal local radio interference and place the transmitter securely in the car power socket. Use high-quality MP3/WMA files and a microSD card up to 64 GB. Avoid charging incompatible devices from the QC3.0 port and follow vehicle electrical specifications (12–24 V).
