Roadtrip Setup Guide

Problem: Avantree Roadtrip does not appear in the phone's Bluetooth list or does not reconnect.

Possible cause: Roadtrip is not in pairing mode or has connected to a previously paired device.

1. Charge Roadtrip if its LED flashes red for low battery.
2. Turn off Bluetooth on other nearby devices previously paired with Roadtrip.
3. Slide Roadtrip to ON; hold the button until the LED flashes red and blue.
4. On your phone, select Avantree Roadtrip in Bluetooth settings.

Expected result: Roadtrip says “Connected” and the blue LED flashes about every five seconds.

If it still fails, clear pairing history or contact support.

Problem: The phone connects to Roadtrip, but audio is quiet or silent.

Possible cause: The phone or Roadtrip volume is low, or the phone uses another audio output.

1. Play audio and select Avantree Roadtrip as the phone's Bluetooth audio output.
2. Raise the phone's media or call volume and rotate Roadtrip's volume knob.
3. If using FM, raise the car-radio volume and make sure both FM frequencies match.

Expected result: You hear the phone through the selected speaker or car radio.

If Roadtrip's speaker is still too quiet, try the FM route; if silent, contact support.

Problem: Phone audio sent through Roadtrip to the car radio has noise or cannot be heard.

Possible cause: A station or local interference occupies the chosen frequency, or the two frequencies differ.

1. Find an unused car-radio frequency with only quiet static, within 88.1–107.9 MHz.
2. Set Roadtrip's FM display to exactly the same frequency and play phone audio.
3. If noise remains, try another unused frequency on Roadtrip and the car radio.
4. If noise persists, temporarily unplug other car accessories.

Expected result: Phone audio plays clearly through the car speakers.

Interference can change while driving. In a new area, retune Roadtrip and the car radio.

If several clear channels fail, contact support.

Problem: The phone is connected to Avantree Roadtrip, but call audio stays on the phone.

Possible cause: The phone routes calls to its own speaker instead of Roadtrip.

1. Answer a test call by pressing Roadtrip's phone/multifunction knob once.
2. Select Avantree Roadtrip as the call-audio output on the phone.
3. On iPhone, set Settings → Accessibility → Touch → Call Audio Routing to Automatic.

Expected result: You hear the caller through Roadtrip.

If calls still use the phone, reset Roadtrip's Bluetooth connection.

Problem: During a call through Avantree Roadtrip, you hear the caller but they cannot hear your voice.

Possible cause: Roadtrip's microphone is muted or its Bluetooth connection needs resetting.

1. Check Roadtrip's indicator during the call. Solid red means its microphone is muted.
2. If the indicator is solid red, press Roadtrip's microphone mute button once.
3. If the caller still cannot hear you, reset Roadtrip's Bluetooth connection and make a test call.

Expected result: Roadtrip's microphone is unmuted and the caller hears your voice.

If the caller still cannot hear you, contact support.

Problem: Roadtrip repeatedly fails to pair, reconnects to the wrong phone, or drops calls.

Possible cause: Saved Bluetooth connections are interfering.

Before you start: This clears Roadtrip's saved pairings; you must pair the phone again.

1. Forget Avantree Roadtrip in the phone's Bluetooth settings, then turn phone Bluetooth off.
2. Turn Roadtrip on. Hold the button about two seconds until the LED flashes red and blue.
3. While red and blue flash, double-click the same button.
4. Wait for a pink LED flash and two beeps, then red and blue flashing again.
5. Turn phone Bluetooth on and select Avantree Roadtrip again.

Expected result: A pink flash and two beeps confirm cleared history. After pairing, Roadtrip says “Connected.”

No pink flash or beeps? Repeat the reset while Roadtrip is in pairing mode.

Still stuck? Contact support and describe the LED and beeps.

Problem: Siri or Google Assistant does not respond through Roadtrip.

Possible cause: The phone is disconnected, its assistant is disabled, or it has no internet connection.

1. Connect the phone to Avantree Roadtrip by Bluetooth.
2. Hold Roadtrip's phone/multifunction knob for two seconds.
3. If nothing happens, enable the assistant on the phone.
4. Check the phone's Wi-Fi or mobile-data connection.
5. Test the assistant directly on the phone.

Expected result: The phone's voice assistant activates and accepts a command.

If it works on the phone but not through Roadtrip, contact support.
