My experience with Car Play
I started to worry after reading all of the issues people were having with the infotainment system on the touring model. I have the EX-T and was trying to use Car Play to play podcasts on my iPhone. The display showed that the podcast was playing but there was no sound. After reading various forum posts and some Google-fu, I ended up downloading the Overcast app. I can now use Car Play to play podcasts using Overcast. Interestingly, as I was troubleshooting the issue I found that this issue only happens with certain podcasts using the native Apple app and car play. I don't know why there would be a difference, but so far have not had other issues. All of the podcasts that would not play on the Apple app do play on the Overcast app.
To troubleshoot, I did a factory reset, started from scratch setting up Bluetooth and car play, and did a hard reset on my iPhone. Probably overkill, but so far so good. I'll post any other issues I notice with it.
My main complaint is having to abandon Waze which has been a lifesaver navigating around traffic in the Seattle area. Apple maps is nowhere as useful for avoiding issues. Navigation, sure - but I wish Apple would allow other apps to integrate with car play. With my old 2003 Civic and an aftermarket sound system, I could use Bluetooth or USB connection and listen to podcasts, music, Pandora, make calls, text using Siri, etc. and have Waze running at the same time providing directions.
