Ringer in Apple CarPlay is too loud
When my phone rings in Apple CarPlay, it rings extremely loud and there seems to be no volume adjustment for it. so you can’t just control the volume of the ringer itself without globally, turning everything down too quietly. This has been a problem for a while, and Apple does not seem to yet have a fix for it. Many people have asked the same question, but Apple does not see it as a priority.
