ok I found this on apple support communities:

"I did some more testing based on your information, and yes, it does show up in Settings once you plug the iPhone into the Carplay stereo via the lightning cable.  Some nice improvements to Carplay from 8.3.  Thanks for the info"

I will check when I leave from work today.  My guess is that its not showing up cause it does not detect a Carplay stereo capable of wireless.  I just sent a message to someone from a Subaru Crosstrek forum that I know has the alpine carplay stereo to see if its working for him and how it works etc....

You know whats weird, I can't find a dang thing out there that even talks about how wireless carplay works.  odd

BT audio is unusable due to loud buzzing in headunit

My sentiments exactly.  I only turn on BT when, for whatever reason the HU will not find my phone, which hasn't happened much in the last couple months.  The quality is atrocious though so I was hoping that they were not planning on using BT for the Wireless CarPlay connection.

I have a sneaky suspicion that this is referring only to the option that enables the use of CarPlay while the phone is locked.  When I initially turned on the car, I was curious if the connection would be made via BT or not, but obviously nothing happened.  Once I plugged the phone in, a pop-up appears on the phone asking if you would like to enable CarPlay while the phone is locked.  I didn't spend really any time looking through my settings beforehand to see if there were any new options for CarPlay (re any options at all, as there were none prior to 8.3).  

I heard that this was something in the beta, but I didn't feel comfortable installing the beta this go 'round.

I can say that one, completely unrelated, option is not available to me in Settings that is widely talked about on the Internet; The ability to download free apps from the app store without authenticating.  I looked high and low for this setting and it is simply not where it should be, let alone the fact that it doesn't exist for me.  This does, however, make me wonder if some carriers have options that others do not?  Like Wireless CarPlay for instance?

I have the 6000NEX and a 16gb iPhone 6 now on 8.3.  I hadn't read anything about the update until someone sent me a link saying that 8.3 would connect to CarPlay wirelessly.  I flipped Bluetooth back on (I had it disabled since I never use it in the car any longer so why waste the battery you know?) and of course, no luck getting connected that way.

 

Once I did plug in the phone I was prompted whether I would like to "Allow CarPlay While Locked" (Which can also be found in General > CarPlay > Car Navigation).  

 

The nice thing, for me anyway, was iTunes music started playing right after the nag screen OK and I just tapped Now Playing.  I had been having issues with music resuming.  I cannot say if that was from iTunes match (To conserve on local storage I started using iTunes Match, which by and large has been very nice but that is neither here nor there), an issue with the phone itself, an issue with CarPlay or an issue with the head unit.  I am leaning toward iTunes Match, but have always been able to see that a song is selected as Now Playing, it isn't until CarPlay is engaged that it will no longer play and I am forced to choose a new Song/Artist/Playlist/Etc. from the Music and/or Now Playing app.

 

I was trying to do a little bit of digging today to find out how the wireless CarPlay works, I have just come up short so far.  I almost hope that it isn't over bluetooth, as the connection isn't too great.  I know the original NEX units, like I have did not have WiFi (I do not know about the x100 series).  Can anyone speak to how the wireless connection is made?  Is it WiFi?

 

I personally wasn't able to notice the album art differences anyone was talking about because I had my contrast and brightness cranked around so much so that I could at least catch a glimpse of it on most albums.  I will change it back and followup to add more of my 2¢ as I find more.

 

Thanks all...s

Well, one day into using this update and and my wanderlust for 8.3 is waxing and waning all over the place.

The problems and/or issues I have come across thus far are:

• I still have the same issues with playlists not playing any longer
• Music will not play sometimes at all unless I turn the car off and on (Unplugging/plugging the phone in does not seem to help
• I set the brightness/contrast levels back to their center points and I cannot see any of the album art (I have gotten used to not seeing it though, but I do miss it)
• When the soft Home button is pressed on the HU, it flashes a bright white (Really more of an annoyance, but it is a bit distracting)

Some of the good points that I have found are:

• Redesigned the buttons (Reply, Sent, Call, Etc.) so that it is really just text and no more flat blue button with negative text.  Now it is just the blue text.  It looks cleaner to me
• The action bar above the Nav Map auto hides after 3 seconds (I believe someone mentioned this before but it is worth mentioning again.  We paid for larger screens, we should get all of that real estate)

One other gripe that I do have is that we are required to OK the nag screen every single time CarPlay engages.  I really do wish that this was an option in settings, that we can OK, stating that we know full well we should drive safely yada yada yada...Hell, make us read it (Scroll down and check an I Agree box) the every time we go into the CarPlay preferences on the iPhone in Settings.  I would be down with that.  The HU already takes long enough to power up, and when I get in my car, I want the music flowing and I want to leave.  I really do not want to interact with HAL.  Okay, I will step off of my soap box now...s

I am not sure about the issues mentioned above, I haven't experienced any of these symptoms , for the album art being faint in the background I really don't have an issue with it because if I go to the home screen the album art is perfectly display to the right all I have to do is click it and whats playing info is displayed with the album art. as for carplay not showing up in the settings, you have to plug the phone with the cable to initialize carplay and have it show up in your settings. as for wireless I am not sure its such a good feature, connecting wirelessly would drain your battery rapidly making you have to plug it in which is what you do anyway and the positive is your phone will be charging at the same time..just my 2 cents guys.

Did "Hey Siri" stop working with the 8.3 update? I could have sworn that it worked before, but my memory could be wrong. I now get no response from Siri when I call out for her.

It still works as it always did. Even when plugged into CarPlay, only the mic on your iPhone can trigger "Hey Siri" commands, so be sure it is within clear speaking distance and the ambient noise is not too high (windows down/loud interior/top down etc).

While I've started enjoying the feature that allows me to use CarPlay without unlocking the phone every time, I've run into an issue with 8.3 and third party CarPlay apps.

If I try to bring up Spotify or Overcast, I just get a blank screen. Same with Podcasts. Music/Maps work. Now Playing will actually hang the UI until the watchdog kills the CarPlay process and it restarts. 

Anyone else seen this behavior?

I haven't had those problems. Try resetting your phone if you haven't. I have had lock ups in the past but been pretty smooth since 8.3.

I couldn't see album art in Car Play before 8.3, and still can't see it with 8.3.  If I turn up contrast & brightness enough to see the album art, even a little bit, the icons/buttons on the main CarPlay screen become totally washed out.  Maybe someday they'll get it sorted out...

Yeah, a reboot cleared it up. Which is weird, since the CarPlay process was getting killed/restarted multiple times on its own. I wonder what state could have been hiding that got cleared on reboot.
