Carplay will work for me continuously for days and then suddenly stop working. After several sessions of this, I am starting to suspect the problem may be the handshake between the phone and the car (our Cayenne's wireless BT based carplay is four years old, slow as a dog to start, but once it connects on the same phones it never fails).
Anyhow - here's what I have found works to restart CarPlay. You want to do this stopped somewhere safe, not while driving.
1) Go to the RR's connected devices settings, and delete your iphone from the list of approved devices.
2) Go to your phone, and select 'Forget this device' for the BT connection to your RR.
3) Search for the car's bluetooth on the phone and select Pair. A pairing request will pop up on both the phone and the RR. Accept both. It doesn't seem to matter which order is used (car first or phone first)
4) Approve all the requests that come up on the phone regarding address book etc.
5) After all this rigmarole - the phone will ask 'enable carplay' - select yes. If this does not happen, go back to step 1.
6) Once you select 'enable carplay' things will work fine for TBD days and fail again. Repeat this sequence again. I have had to go through this process 4 or five times in the last 5 months.
7) Stopping/restarting the car, shutting down and rebooting the phone do not have any effect on success or failure of step 5.
8) If you are the primary user of the car and you have multiple devices paired - one of the other devices will become the primary device once you do this. You can go into the connected devices setting and select your phone to be the primary device.
Also note - I do not connect my phone to the wifi hotspot of the car. In fact, I've not even provided the SSID and password of the car wifi hotspot to my phone. Carplay initiates over bluetooth and then switches to the wifi radio in the phone to talk to the wifi connection of the car (this is just using higher bandwidth wifi for the phone and car to transmit data back and forth, nothing more).
I've also experimented with wired USB carplay. Once the carplay connection fails - it will not come up on wired USB either.
I hope this sequence is of help to folks who are periodically experiencing this. This SHOULD NOT happen. I suspect it's a bug somewhere in LR's software stack, not Apple.
