A:AnswerYes. I use mine every day with a smart phone for business and all other calls. Plug in ,dial up an unused FM channel, your set to go. My only issue
Is you need to adjust the volume between normal
stations and the channel you use for the bluetooth.
Great little mike is attached .
A:AnswerThe microphone has a piece of velcro so you can attach it to your dash. People should be able to hear you better because you can get this microphone closer to you than if it was built into the transmitter.
A:AnswerOne of the USB ports on the unit is for playing USB media from a thumb drive and supports charging at 1A. The second is a QC 3.0 charging port that supports 5v/3A, 9v/2a, and 12v/1.5A charging. Both ports are standard USB-A style ports.
A:AnswerThis unit is used to connect a Bluetooth phone to a car stereo via FM transmission. This unit will not accomplish what you are looking to do, unfortunately.
A:AnswerYour phone should be able to tell you how much data each app uses, the higher quality content uses more data. The amount of data that goes through your phone has nothing to do with this device.
