Hi all, for some reason my PCM is not recognizing my iPhone when I plug it into the USB in the center console. I have tried to reset the PCM and it still won't recognize it. Anyone experience this? Any suggestions on how to fix it?

Thanks!

 

How old is your phone?

 

It’s an iPhone 16 Pro, brand new. I actually ended up figuring it out. Had to drive it a few times after resetting the PCM and then plugged it in while in accessory mode and it ended up prompting me for CarPlay again.

 

USB connection for CarPlay is a bit hit-and-miss for me. 30% doesn’t connect first time. Today Waze connected but Spotify was playing through phone. Unconnected and reconnect usb to fix.

 

I have a 16 and it pairs fine. I also use a thingy thing (technical term) for wireless.

Also, the 16 is USB C. The Porsche is USB A. How are you translating? My experience has been with the cable. Get a new one Apple and not 3rd party. Or go wireless(better as it is iPhone agnostic and can handle multiple phones serially.)

 

The same thing used to happen to me w/ the PCM 4.0 in my previous Cayman S. About 50% of the time, the OEM CarPlay system would not connect when I plugged it in and started the car. The only way I could reliably connect was to wait until the car was running to plug it in.

Ironically, the Mr12Volt wireless CarPlay module that I added to the PCM 3.1 in my '14 TTS works 100% of the time as long as the phone is within range of the car. It boots up as soon as I put the key in the ignition and before even turning the key. It even works with my phone is in the house, and the car in the attached garage. If I shut the car down with CarPlay selected, it's there immediately the next time I put the key in the ignition.

PCM 3.1 w/ Mr12Volt added is far superior to the PCM 4.0 system was, at least in my experience. Moreover, addition of Mr12Volt retained all the OEM PCM 3.1 functions.
