What is the reason for the excessively loud default navigation volume in CarPlay?
2 Answers
Because the call volume on the phone is set to maximum. Introduction to CARPLAY features is as follows: CarPlay Map Navigation: Click the map icon in CarPlay to activate the map navigation function. CarPlay can utilize the map feature to complete route planning and navigation, estimating travel time based on real-time conditions. CarPlay is an in-car system released by Apple Inc. in the United States, seamlessly integrating users' iOS devices, iOS user experience with the dashboard system. CarPlay Phone and Messaging: Through Siri, CarPlay can make phone calls, listen to voicemails, and of course, these can also be done via direct touch. Additionally, if Mandarin pronunciation is standard, Siri can also reply to text messages through CarPlay.
When the CarPlay navigation volume is excessively loud by default, it is mostly due to system settings. For example, Apple's CarPlay controls navigation volume and media volume separately, and your app's default value might be set too high. I've encountered a similar situation where navigation apps like Apple Maps or Google Maps have their own volume adjustment options—setting them too high can cause distorted output. Another factor is the car's audio system output not being properly adjusted, as some manufacturers preset higher volumes that affect the CarPlay signal. Software bugs are also a common cause, especially after system updates cause conflicts. I recommend first checking your phone settings—navigate to the sound menu and adjust the navigation audio level, or try restarting the device. Don’t overlook the car’s audio balance settings; setting it to a neutral position can help alleviate the issue. In short, tweaking the settings a few times usually resolves it without the need for immediate repairs.
