iOS 11.2 breaks CarPlay on 2017 A4?
 

I just updated to iOS 11.2 over the weekend, and now CarPlay doesn't work. Anyone else with this experience?

Looks like the answer is a definite "yes". Discussion is in the "Apple CarPlay Problems" thread: https://www.audiworld.com/forums/a4-...blems-2915342/

It's working for me on iphoneX. but it's very glitchy. If my pre-sense goes off (which it likes to beep at me in heavy traffic), I can no longer get to the carplay screen. I have to unplug, wait, and plug the phone back in

So far CarPlay is working fine for me. I have an iPhone 6S with 11.2 on a 2018 A4 with MMI version 1118

So, I played around with things a bit more, and I was able to get CarPlay working. This is what I found:

2017 A4 Prestige, MMI firmware: 0918

iPhone 6s + iOS 11.1.2 + Apple cable = CarPlay
iPhone 6s + iOS 11.1.2 + Belkin cable = CarPlay
iPhone 6s + iOS 11.1.2 + SyncWire cable = CarPlay

iPhone 8 + iOS 11.1.2 + Apple cable = CarPlay
iPhone 8 + iOS 11.1.2 + Belkin cable = CarPlay
iPhone 8 + iOS 11.1.2 + SyncWire cable = CarPlay

iPhone 8 + iOS 11.2 + Apple cable = CarPlay
iPhone 8 + iOS 11.2 + Belkin cable = CarPlay
iPhone 8 + iOS 11.2 + SyncWire cable = NO-GO

Note: Both the Belkin and SyncWire cables are listed as "Apple Certified"

What a huge pain in the butt.

iPhone 7 + iOS 11.2 + AmazonBasics Apple cert. cable = CarPlay

I have an iPhone X and use the Audi cable and haven't had any issues running iOS 11.2. It's been a bit fickle with the iPhone X in general, but I haven't noticed any differences from 11.1.x to 11.2.

I have an iPhoneX with iOS 11.2 and I use the ridiculously overpriced USB to lightning cable that Audi sells. Worked just fine in my 2018 Prestige A4.

MMI version 0918

Anker Cable (but also tried Apple and Audi)

iphone6s and X

Problems: 1) whenever pre-sense dings at you, or you go into reverse and get the parking camera, there's a 80% chance you can't get back into CarPlay menu
2) Spotify and Pandora almost always displays "Unknown track, unknown artist, unknown album."
3) Apple Music almost always displays "unknown artist"

EDIT: also Bluetooth album art. I'm not entirely sure how this has been integrated, because I know the new bluetooth specs allow for album art to be trasmitted, but I get a really 50/50 chance of seeing my art or the generic "Urban" icon

As for problem number 1, my car does that. For me, simply pressing the Parking Assist button below the climate control removes the screen and CarPlay reappears.

Can't speak for the other problems since I only use CarPlay to be able to browse Amazon Music playlists that I have.
