This LoHi Bluetooth FM Transmitter for the car uses a wireless Radio Adapter. It makes you hands free to make calls which are clear with an empty radio station The 2.0'' Color User Interface Display is super user friendly. The QC3.0 Fast Charging feature is great for charging your phone quickly. You can play music through bluetooth, 6 EQ Mode, and AUX Input/Output. This updated my later model vehicle and I'm now hands free and safe on the road!
