## Questions & Answers

**Q: How to use the FM radio function?**
A: 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.

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

**Q: How do you answer or ignore incoming calls?**
A: 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.

**Q: Will this work through the alexa app ?**
A: Yes, it is compatible.
1. first install Amazon Alexa app - can be installed on any Android 9.0 (or higher) phone/tablet and also iOS.
