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.

It’s something I’ve only experienced a handful of times over the last decade.
