Hi everybody, I did not scroll through all 9 pages of this question/problem about CarPlay, but definitely identify with many of the issues here. After updating to iOS 10, I kept getting messages like "no device connected" or "device not compatible" on my Honda Civic 2016. I have tried everything from "forgetting" the phone via the CarPlay app, resetting the phone, power on/off the phone etc to no effect. Also changed cables multiple times, and now using Apple cable. So ... here is what temporarily works for me. I primarily play OFFLINE music (meaning music that is physically on my phone), DOWNLOADED podcasts, and use maps/messages apps while driving using CarPlay. What I do is turn car on WITHOUT plugging in phone, unlock phone, open the app I want, in my case mostly Music. Start playing the songs from the phone first. THEN I plug the phone into the car (by now the Honda interface is up and ready). Then voila, CarPlay works and music switches over to the car speakers. Same with Podcasts and Maps. If I need directions to go anywhere, I start the guidance thing on the phone first without plugging it into the car's dedicated CarPlay usb. Then I plug phone in and a few seconds later, map guidance starts talking to me via car speaker and map interface shows up. To test all this, I left the phone in the car and went into the grocery store. Came back, phone is already plugged in, started the car and the incompatible messages came back. My solution, while slightly inconvenient, works for the time being. As long as I can use CarPlay interface to play music, occasionally text and use map, I'm happy. One more thing ... I noticed the same thing with AirDrop after upgrading to iOS 10. I often AirDrop pictures between my phone and my MacBook laptop. With previous iOS I did not have to "unlock" or wake phone up, but since upgrade, AirDrop only shows up AFTER I unlock/wake phone with my touch I.D. or passcode. It seems like the device must be ON and UNLOCKED for communication to work. If phone goes back to lock mode, I notice the AirDrop receiver on the laptop shows no device found even though it is sitting 2 inches away from the computer. Sorry for long post, and hope this helps 🙂
