Roadtrip - FM Static or Noise Issues – Avantree Support

Before You Start: Static, echo, missing call audio, or interrupted calls may be caused by FM interference or audio settings.

Step 1 – Check for Possible Interference

Other electronic devices or accessories in your vehicle may cause signal interference. Temporarily unplug other chargers or electronic accessories connected in your car, then play audio through Roadtrip again to see if the issue improves.

Step 2 – Fix FM Static or Noise

Find an unused FM frequency on your car radio with no music or voices.
Set Roadtrip to the same frequency.
Play audio and check whether the static disappears.

Still hearing static? Try another unused frequency on both devices.

Static returns while driving? Nearby radio stations may cause interference. Change to another clear frequency.

Step 3 – Fix Excessive Bass or Distorted Sound

Lower your phone’s volume slightly.
If available, set your phone’s music Equalizer (EQ) to Normal/Flat.
Reduce the bass on your car stereo.
Try another song or music app.

Sounds normal through Roadtrip but distorted through your car speakers? The issue may be related to FM transmission or car audio settings.

Distorted in both modes? Try another song or phone to check whether the audio source is causing it.

Step 4 – Fix Echo or Noise During Calls

Lower the call volume slightly.
Make sure Roadtrip’s microphone is not covered.
Reduce your car stereo volume if using FM mode.
Make another test call.

Still hearing echo or noise? Reset Roadtrip using the guide below, then reconnect your phone and test with another call.
