I’m wondering if anyone else has seen this? When I drive in certain areas, my iPhone will disconnect from wireless CarPlay for ~30 seconds. I’m guessing there’s some sort of interference, but I’ve not seen this behavior in other cars.
This is in my 2023 G80 M3.
It’s just interference. There is likely a high-powered transmitter in the area that a neighboring building is connected to. The frequency of the transmitter just so happens to be the same channel as your particular CarPlay receiver, which causes the disconnection. This is no different than your home router experiencing interference from neighbors, Bluetooth devices, and microwaves. There is nothing you can do about it. Your next vehicle will likely not experience the interference in that same area since the WiFi channels vary from car to car (but you may discover that there’s another area with interference).
The FCC recently opened up the 6GHz band for low-powered devices which future vehicles will eventually adopt. This may resolve interference issues in the future, but only if there are no high-powered transmitters on the same frequency… only time will tell this though.
I would buy that; however, not all vehicles with wireless CarPlay have the same issue (including my previous car and my partner’s X5) at the same location. It’s clearly a shielding issue that needs to be resolved.
