Phone call volume is not turned on. The volume of the car navigation system is not activated. Below is an analysis of why there is no sound when navigation is connected to car Bluetooth: 1. Solution: Go to the phone's Bluetooth settings, click the gear icon next to the paired device, and turn on "Call Audio" and "Media Audio." 2. Reason: This might be because when you got in the car, your phone's volume needed to be turned on again. Often, it automatically resets to 0, so naturally, there's no sound. Gradually increase the volume a little, and you'll know if there's sound.

I guess the issue with your phone's navigation having no sound over Bluetooth might be on the phone itself. Open your phone's settings, go to the Bluetooth devices list, select your car's device, and check if the audio output isn't enabled or if the navigation app doesn't have the necessary permissions. Sometimes, the phone's media volume is turned down or muted, which can cause this; try increasing the volume with the volume buttons while the navigation is running. Also, restarting your phone or reconnecting the Bluetooth often solves the problem—I've encountered this in my car, and it only worked properly after doing so. Don't forget to check the navigation app's own settings to ensure voice prompts are enabled. Always pay attention to these details while driving, as weak Bluetooth signals or interference can also cause sound to cut out, and stopping to re-pair the device often helps.

I've been driving for over a decade and encountered many Bluetooth connection issues. No navigation audio usually means the car stereo settings aren't properly adjusted. After starting the car, turn the audio control knob to switch to Bluetooth input source - some vehicles require manually enabling navigation audio output in the central control menu. The car audio volume might have been accidentally lowered or muted, so remember to check system settings for relevant options. Multiple connected devices may compete for audio channels; try disconnecting others. For older car models, outdated system software may cause incompatibility - consider updating the firmware during maintenance. Car Bluetooth stability depends on signal strength; parking in better locations can prevent interruptions. Regular checks of the vehicle's electronic systems can prevent such minor issues.

I've encountered situations where the navigation Bluetooth has no sound, with the core issue being unstable connections. After confirming successful pairing between the phone and the car system, try again; disconnect and reconnect once, or restart both devices. Check the device status in the phone's Bluetooth settings to ensure it's normal. The navigation app must have voice output permissions enabled - verify this in the settings. A simple solution is to increase the phone volume and maintain a smooth connection. If the sound is intermittent, moving closer to the car's infotainment unit usually solves it. These minor issues are common in daily use and can be quickly resolved without delaying your trip.
