You can also use Carplay for maps on one iPhone and listen to Bluetooth audio from another.

Are you at your wit’s end trying to figure out how to get wireless Carplay to work? Well, I finally figured it out.
The problem:
Wired Carplay has always worked for me but Wireless Carplay only worked with my dad’s iPhone 12 pro and not mine. Despite multiple attempts at forgetting and re-pairing the Carplay device, it just would refuse to connect wirelessly. I figured it was due to my aging iPhone XS not being compatible or some other bug. I got a new iPhone 15 pro recently and I was excited to finally get wireless Carplay to work only to be met with the same issue which meant this was probably something software-related.
The troubleshooting:
I tried resetting the Hycross infotainment to see if that would fix it. Did not work.I reasoned the problem probably wasn’t with the infotainment since it was working with my dad’s phone.
The solution
On your iPhone, go to settings, general, reset, and then reset network settings.
Note: this will also remove all wifi passwords so make an iCloud backup first.
We will ignore the carplay tab for now on both iPhone and infotainment.
Next, go to Bluetooth and pair the car via Bluetooth like you normally would for Bluetooth audio.
You will get a notification on both the car and the iPhone telling you the Carplay device is available and asking you if you want to use it. Click yes on both devices.
You will get another notification asking you if you want to use wireless Carplay. Make sure to click yes on that too. I think I mistakenly clicked “no” when I first paired the car to check the audio quality during PDI before taking delivery of the car and the phone remembered this setting.
Only if the infotainment gets stuck on “waiting for confirmation from your phone” :
Go to wifi on phone and click and join the “MYCAR########” network. A password will not be asked, it would have been autosaved during the pairing process.
Once the iPhone joins this network created by the car, the carplay tab on the infotainment will light up. Enjoy using wireless Carplay.
Wireless Carplay not connecting automatically/sporadically:
Go to wifi and click on the (i) next to the “MYCAR######” network. Then make sure autojoin is turned on.
And that’s it. Carplay may not connect automatically when you are close to your home wifi because your phone would be connected to that instead. From now on, when your phone auto connects to car Bluetooth, it should auto connect to car wifi too and you can use all the cool features introduced in iOS 17.
Another nice feature I noticed even before shareplay is that you can connect multiple phones to Bluetooth at the same time and switch between audio sources from the steering mode button. You can also use carplay for maps on one iPhone and listen to Bluetooth audio from another paired phone.
