How to use the FM radio function?

To set the Roadtrip into FM Transmitter mode, set the power switch on the side to "FM". Here is a video you can refer to. Please feel free to ask questions if there is anything else we can help with.

Can i run road trip and external speaker simultaneously via my device? my car radio doesn't work well.

If you are trying to play music through the Roadtrip and a portable external speaker at the same time via your smartphone, you unfortunately cannot. The Roadtrip can only pair with a smartphone and not with external speakers. If your car radio works, you can try using the Roadtrip's FM transmission function to play your audio through your car stereo.

How do you answer or ignore incoming calls?

To answer (or end) a call, short press the Bluetooth button once. To reject a call, hold the Bluetooth button for 2 seconds. Actually we've a user manual that comes with the item that will provide a clear instruction.

Will this work through the alexa app ?

excellent connectivity, best volume

A very useful device for anyone who wants to use the phone in a car that is not equipped with Bluetooth. Pure, clear sound and easy to use. The device is small in size and its battery lasts a long time. It does not require any wire connections
