PCM - Hints and Instructions
In my case, I either want to listen to my own music or various SiriusXM stations. For my music, I have loaded up a SD chip and set it up to shuffle tracks so I don't have to interact with the PCM while I am driving. If I want to skip a track, I use the skip button on the steering wheel. I don't know if I can set up and select play lists on the SD so I shuffle through Rock, Pop, Jazz and Classical randomly.
I have not quite figured out how to easily switch XM channels other than by using the PCM talk button. I don't know if there is any way to skip through favorite channels, and I am not quite sure yet how to even set up favorite channels. Ultimately, I do not intend to subscribe to this SiriusXM service when it runs out. Instead, I intend to use the Sirius app on my iPhone through Apple CarPlay, since I have another subscription that allows that. But I still feel that switching between PCM and CarPlay is glitchy and the manuals are not clear about how to easily switch between them.
So, please add your input.
I can offer my thoughts regarding CarPlay and how I puzzled it out based on my needs.
Second, I do not let the CarPlay application on my iPhone connect to the PCM via Bluetooth. I do this by following this path on my iPhone: Settings > General > CarPlay > PORSCHE > Turn the CarPlay button to the Off position.
Third, I do this so that CarPlay will work only with the iPhone connected via the #2 USB Port in the Console. This accomplishes several things.
B.) I have unlimited data on my cell phone plan at a speed far in excess of what the integral AT&T SIM Chip provides. Using CarPlay wirelessly with Bluetooth shuts off my iPhones access to the cell phone network and thus the internet as well.
B.) I have a number of functions in my electronic life that my phone can not manage if it is tied wirelessly via Bluetooth to this car, because that shuts off my iPhones access to the cell phone network and thus the internet as well.
C.) If I allow my iPhone to connect to the car via wireless CarPlay incoming phone calls are quite garbled and often hard to decipher. With the iPhone hardwired, everything, including CarPlay, works perfectly
D.) It keeps my iPhone fully charged, which is actually the least important advantage to this setup.

I've since changed the USB/Lightening Connector Cord to a 90* version for the sake of appearance more than anything else.

BTW, the ProClip mount offers a great, out of the way position to hold your phone.
Easy snap on and off

Most interesting! I might try carplay this way. I do think that verzion is contributing to some of your issues. I believe they do limit access to data depending on how you are using the phone.
My iPhone connects to the car using the Bluetooth connection for ALL but one thing. This one thing is, I have prevented the CarPlay function (and ONLY the CarPlay function) from connecting using the iPhone's Bluetooth system. This prevents the CarPlay app on my phone from hijacking the iPhone's WiFi capability to communicate with the car. This is because CarPlay when connecting wirelessly to the car uses BOTH the iPhone's Bluetooth system AND the its WiFi system. Forcing CarPlay to ONLY use the hardwire connection, results in my iPhone's WiFi system remaining available for whatever I might choose to use it for. I can still make and receive calls via CarPlay. In fact, ALL of the CarPlay functions involving the iPhone are active and perform flawlessly.
The only downside that I can find (so far), is that one MUST plug the iPhone in for CarPlay to work.

I want to use my iPhone's Hot Spot for the PCM rather than to pay for an additional data or cell phone service (SIM Card) that would essentially be redundant to the capabilities that already exist via my iPhone/Verizon. Also, the AT&T network's coverage is NOT a particularly good here in the L.A./Southern California area.
My iPhone also triggers the opening and closing my garage door as it accesses or cannot access one of my home networks. Similar tie in to my home management system.
Another option I use, once and awhile, is to employ Google Maps on my iPhone and at the same time have Waze running via CarPlay on the PCM.
