Yesterday I used Carplay for the first time since upgrading to iOS 14 and it wouldn't let me play any of my music. If I went to the music app it told me that I couldn't do it whilst driving, I should go back to the app once I had stopped. Siri was useless too, it kept telling me it couldn't find stuff in Apple Music, it seemingly ignored the 85Gb of MP3 files on the phone. So end result was no music.
I didn't check when I got home if the Music app could see my MP3 files when the car was parked, I assume it could but I'll check later.
Podcasts worked fine, it would let me see my podcasts on the car screen.
I assumed that Carplay gave the same experience irrespective of the car, but I was wrong. I mentioned to my brother that when Im driving I can't dial a phone number unless it's saved as a contact. I can't get the dialpad to display (it says I can't do it whislt driving) nor can I dictate a telephone number and get Siri to dial it. He said that the dialpad is available for him when he's driving.
Can anyone else comment on if they can browse locally stored music and get the dialpad to open whilst driving?
