If your Apple CarPlay connection randomly drops out while driving, the cause might not be your iPhone, cable, or car.

Radio interference, of all things, could be the cause of your troubles.
An Axios report once detailed a peculiar phenomenon in Boston, where drivers lost their CarPlay or Android Auto connection at the exact same spots. Similar “dead zones” are likely in other cities, though may go unreported.
CarPlay units don’t handle GPS navigation on their own. Instead, they maintain a direct Bluetooth or Wi-Fi connection to your iPhone, projecting a view based on its connection to the internet and GPS satellites. When that wireless link between the phone and dashboard is interrupted, navigation can fail and the connection can drop.
I have a spot in grapevine tx between a stretch of road next to a petroleum storage facility and a nursing home that kills all wireless carplay systems. Drove many vehicles with built-in wireless CarPlay cars with wireless CarPlay adapters and aftermarket radio systems that will die in this particular stretch of road. Some systems can recover from the interruption some systems cannot. Even the new Mercedes electric vehicles have this problem.
It’s something I’ve only experienced a handful of times over the last decade.
The bottom line is if you regularly lose CarPlay connection in the same place, you may be driving through an invisible field of radio interference. It might not be fixable, but knowing the cause could save you hours of frustration troubleshooting or booking unnecessary service appointments.

Experts point to potential interference from nearby radio sources, especially in the 2.4GHz band. In Boston’s case, speculation includes point-to-point microwave links, broadcast antennas, or unlicensed transmitters.
