2024 C2S Navigation Randomly Stops
Id did a few searches for this problem and didn't quite find anyone experincing the same issue, so I an apologize if its already been written about. My 2024 C2S navigation randomly stops navigating when im driving anywhere from 15-45 minutes into a drive. There are not messages, it just stops navigating. Like it forgets I'm trying to go somewhere. This has happened since new. Has anyone experienced this?

My suggestion is to go to your dealer and have them diagnose. I had an issue with my PCM unit not logging My Porsche ID, and it turned out to be a faulty Master Communication Module. Which they miraculously had one in inventory. In talking with the tech and service personnel they have been replacing a few on these and had them in their parts inventory. Took about 45 minutes to replace.
My car is a April 2024 build C2S. I have the feeling that Porsche had to find new suppliers for a bunch of electronic modules given the war in Ukraine and the associated custom restrictions. New suppliers = new journey up the quality curve....
Edit: your other option is to try the PCM Hard Reboot: hold 2 fingers in the upper right hand side of the PCM screen for 10+ seconds. The PCM will boot into Engineering Mode. Select "Exit" and the PCM will reboot into normal mode. I Did not select any of the other options available....only Exit.

There is one particular area, near where I live, where a GPS will disown me and/or Sirius Radio will cut out. (JCT I-5 and I-405 in Irvine California)
I'm guessing that there is a data beacon/beam of some sort (not an entirely unusual way to connect two or more systems in fairly close proximity to each other) that intersects the highways in this area. It's fairly consistent and is not dependent on what car I'm driving. Although when using the southbound carpool lane from the I-405 to the I-5 (a fly-over) this phenomena is almost guaranteed to intrude.
So if your issue seems to be fairly consistent geographically, this might be what you're encountering.
