And, if you don't mind my asking, how do you think Quick Replies has improved? I'm not seeing a big difference, but I may be missing something, too.They definitely fixed something in the media portion of it as a podcast app I'm on a beta of OS no longer outright crashing to the CarPlay home screen as soon as I start playing a podcast. Now it just doesn't play instead (the dev isn't focused on 10 yet).
Also the Apple Podcast app while in CarPlay no longer crashes every 15 min like the last beta.
In general it's faster with a lot less lag while moving between apps. I've got a Pioneer 4100NEX.
