Hey, I've also encountered the issue where CarPlay has sound but no display. Let's start troubleshooting from the basics. First, check the USB cable – if it's loose or damaged, CarPlay signal transmission can be problematic, allowing sound to work but causing display transmission to fail. Try switching to a high-quality original cable or clean the dust from your phone's port. Next, restart the relevant devices; simple steps like rebooting your phone and the car's infotainment system can eliminate temporary software conflicts. Then, verify the correct settings – in your iPhone's CarPlay settings, make sure your vehicle is authorized to display the screen. If the software is outdated, updating your iOS or the car's infotainment system version might help. By the way, regarding compatibility, some older car screens may not adapt well to newer iPhones, so consider upgrading the car's software. If none of these work, visit a professional repair shop to check the display hardware or related modules. Remember to prioritize safety while driving – if the issue persists, use your phone for navigation instead.
