What is the reason for no sound in CarPlay navigation when connected?

It may be due to a disconnection or signal loss. Here is the relevant introduction: CarPlay: What is CarPlay? It is an in-car system launched by Apple Inc. in the United States. This in-car system can connect with a smartphone, offering great convenience. It can be connected either via a wired or wireless method, allowing the smartphone's screen to be mirrored onto the car's central control screen and enabling the use of related functions on the phone. It is an excellent in-car system. Solution: You need to disconnect the phone from the car's system and reconnect them. After disconnecting the phone and the car's system, restart both the phone and the car's system, then reconnect them. Alternatively, reset the car's system to factory settings and then reconnect it with the phone.
CarPlay navigation having no sound can stem from several issues. Common reasons for no audio after connection include incorrect volume settings—either the phone volume is too low or the car stereo's navigation audio control is set too low. Check the iPhone settings under Sounds & Haptics to ensure the navigation volume is normal, and verify that the map app's voice guidance is enabled and routed to CarPlay. Poor-quality or aged USB cables may cause unstable connections and audio dropouts; try switching to an original cable. The car's head unit might have a dedicated volume knob—turn it to increase the volume. Outdated software is another culprit, as older iOS or car firmware versions may not support the latest navigation features—update promptly to avoid bugs. Hardware issues like blown speakers are rare, but it's wise to check the audio system output for safety. While driving, prioritize safety—pull over to troubleshoot instead of handling it while distracted to prevent accidents.
