Hello, I wanted to see if anyone knows a way to add Apple CarPlay to the factory Radio/Navigation system for a 2015 Prius? Also, is there a function to correct volume when using your iPhone via USB or Bluetooth. When I listen to music or my Audiobooks, the volume is super low.. Thank you,
Not without replacing the entire headunit with an aftermarket one. When you're connected via USB or BTA, go to your iPhone's volume setting (either control panel or just press the + button) to increase the volume on the phone.
There's a setting in itunes to normalize music files so the audio levels of music files will be relatively audible as other music files. In other words, audio tracks that are lower in volume will be amplified. Opposite is true, which ever audio/music file that's too loud will playback with volume relatively lower to keep volume constant. This may hear some kind of compressor and/or limiter effect for all you audiophile officinado like me will know what that is.
