The Apple device cannot be accessed via USB at the moment.

Hi everyone,

I’m having an issue with Apple CarPlay on my 2018 Ford Focus equipped with SYNC 3.

Every time I connect my iPhone via USB, the screen shows the message:
“The Apple device cannot be accessed via USB at the moment.”
The phone charges normally, but CarPlay never starts.

Here’s my setup and what I’ve already tried:

  • SYNC version: 3.4.14 (build 23188) — updated from 3.0 using a USB flash drive
  • iPhone: latest iOS version
  • Cable: original Apple Lightning cable (tested and works for data transfer on PC)
  • Tried on another iPhone: same result
  • Android Auto works perfectly, the issue happens only with CarPlay
  • USB flash drives work normally
  • The system even shows the prompt to accept CarPlay, and CarPlay is enabled in SYNC settings
  • Wireless CarPlay adapters also fail and show the same message
  • I’ve reset SYNC to factory defaults, reset network settings on iPhone, and checked “Allow USB accessories” — none of that helped

So the only persistent issue is this message:

“The Apple device cannot be accessed via USB at the moment.”

Has anyone else experienced this on version 3.4.14 build 23188?
Any tips or confirmed fixes would be greatly appreciated!

Thanks in advance!

Tried a different USB port?

Don’t assume that the USB hub is CP compatible just because it is a 2018 vehicle. Check the part number.

Can you try Carplay on another Ford to see if you get the same message?

yes…

Yes, I tested in ecoSport 2018 and function all right

Sounds like a bad USB media hub
