If you’re experiencing choppy audio first try other tracks.
If that doesn't resolve the problem check for interference from other devices near you. Remember to check your own mobile and others in the car. Do they have a WiFi enabled hotspot enabled for example? If so disable them and check the audio again.
It may also be that you are driving through a particularly bad area full of interference to be sure to test playback over a long duration of time in different areas.
If your playback device is actively searching for other hosts to connect to this can sometimes interfere with streaming audio. So check your source device and exit any Bluetooth setup screen it may still be running.
