Review: Superb background rejection for speakerphone, and everything works as it should - - Tested with iPhone 14 Pro - Pairs easily with phone, haven't tried its 2-phone capability. Very easy to set up an use. - Speakerphone totally rejects background sound even with car windows open and produces no voice dropouts even under severe background conditions. The parties I talk to are very thankful for this; they have long been annoyed by the background sound and dropouts with several other speakerphones I have used including the phone's built-in speakerphone and my Bluetooth 2-way speakerphone hearing aids. Part of the key to this good performance is probably the microphone being so near my mouth, since the unit is mounted on the car visor. - The built-in speaker is as good as an inexpensive small speaker is expected to be; being very near the driver's ears helps it to work without having to be turned up to distortion level. - The FM radio link is as good as FM radio links can be, i.e. there is some hiss and crackle but on the whole, with my fairly good quality car speakers, the speakerphone and music streaming sound over them is much better than the Roadtrip built-in speaker. - The button is very convenient for answering, rejecting, and ending calls and redialing, and for initiating Siri commands. But with the microphone so near my face I don't have to speak Siri very loud anyway, unless I have the speaker or car radio speakers playing loudly. - This is the only visor-mounted product I have found that both streams audio via Bluetooth and acts as a speakerphone, and it works very well. - Allows different phone apps to selectively use it, e.g. I can stream music over my hearing aids and use Roadtrip as my speakerphone. So do I have any complaints? Only some slight ones: - The unit is a little heavy, you might need to tighten the hinge on our visor to keep the visor from sagging, or add velcro to hold the visor up. - I am tall and was annoyed by the unit being mounted on the visor, particularly when getting in the car while wearing a hat. So I used velcro to mount it on the ceiling above the rear-view mirror. I have not tested its microphone pickup and background canceling performance in this configuration yet.
Review: Works perfect - I bought one and used it for a short time and it developed an issue with the bluetooth where it would whine over the radio, so I contacted Avantree and they sent me a new one free of charge. No issues with this one at all. Provides clear audio (as clear as FM can be), turns on when I need it to, and sometimes when I don't want it to (make sure it won't detect movement outside of the car), and even tells you when the battery is low. It also has a changeable battery in case the battery completely depletes. It is rechargeable, but it's nice to not have to create ewaste.

## Features

- [2-IN-1 SPEAKER & FM TRANSMITTER] Use the Roadtrip as a Bluetooth speaker for calls, voice assistant activation, or directions, or use as an FM transmitter to stream audio from your phone to your car's stereo via FM.
- [CRYSTAL CLEAR CALLS] Hear every conversation clearly with dual 3W speakers, and ensure your voice is heard just as clearly with the built-in noise-reducing microphone.
- [HIGH-DEFINITION SOUND] Despite its compact size, the Roadtrip’s dual 3W speakers deliver powerful, high-definition audio with emphasized clarity.
- [SMART AUTO POWER] The Roadtrip automatically powers off as you leave the car and your phone disconnects. When you return, its built-in motion sensor detects your presence, powers on, and reconnects to your device as you open the door.
- [EASY TO USE] Turn the rotary dial to adjust the volume, or press it to activate your phone's voice assistant for hands-free calls, texts, and more.

## 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.
Android link for Google Playstore:
https://play.google.com/store/apps/details?id=com.amazon.dee.app&hl=en&gl=US

2. Next - set your phone to use Alexa as the default Personal Assistant:
https://www.amazon.com/gp/help/customer/display.html?nodeId=GYSXE9CTW5AS2BZU#:~:text=Open%20the%20Settings%20menu%20on,Choose%20Alexa.

3. to launch Alexa on the CK12 - press and hold phone key for 2 seconds (don't hold too long or it will go into pairing mode!)

### ⭐⭐⭐⭐ Great product
*by I***N on October 14, 2024*

No directions needed. Battery was charged when I pulled it out of the box. My phone immediately connected to it. First time using it, played music straight from the unit. Sound is ok for what it is. Second time using, tried the FM transmitter. Selected a frequency and my work truck picked it right up. When I got out of the truck, I left the unit on. When I returned and started the truck, music instantly played from the truck speakers. There is slight static in the speakers at very low volume. Highly recommend it for those with older vehicles that can't connect directly to their vehicle sound system. I'd give it 5 Stars (and probably should) if it weren't for the static. But I don't know, never used an FM transmitter before. Might just be normal. Again, I want to emphasize you could only hear the static at low volume.
