My car has wireless CarPlay and I use it daily. There is one quirk I have noticed and I’m not sure if it is a general issue with wireless CarPlay or just Volkswagen’s implementation and that is there are times that the phone gets disconnected and the infotainment screen goes black. My assumption is that it has to do with a signal that is stronger disrupting the connection causing the issue as it only happens in certain areas and not always. The latest area I know it will happen is on a bridge that is having construction done on it. When we get over the construction equipment the CarPlay disconnects and will reconnect a few minutes down the road. I’ve actually wanted to get a HackRF One to capture the signal and see if I could tell what it was but I can’t justify spending $300 for just that.

There's a complex intersection near my house where my aftermarket Atoto CarPlay head unit will also reliably disconnect. Fortunately, after a firmware update to the head unit, it will now at least reconnect automatically; previously, I'd have to disconnect and reconnect the phone.

(Without any data to support,) I believe it to be a complexity of map issue (maybe causing a buffer overflow) rather than an RF/WiFi interference issue. It seems far too repeatable for it to be an RF issue.

I would be curious if that intersection ever stop causing disconnects. There was an intersection that would cause disconnects only from one area of the intersection (the east side of the intersection) and one day the disconnects stopped. There was another area near a water tower that would also disconnect the CarPlay and that no longer causes an issue. There was a water pump station near the first intersection so I was thinking it could somehow be related to the operations of the equipment. I am betting that once the construction is done in the area I’m having issues currently the issues will go away.
