Technical Background
On vehicles with a single USB port, the Apple authentication chip is in the USB port. On vehicles with 2 USB ports
(one front and one rear), the authentication chip is in the USB hub. CarPlay will not work from a rear USB port.
For static connection issues with:

No faults

No cable issues

No debris in the phone’s cable port
Swapping the USB port or hub with a known good part should be the first step in diagnosis.
Service
If connection issue occurred after an iOS update, ensure that CarPlay is switched ON in the CarPlay settings of the
phone.
When encountering intermittent CarPlay connection issues, it’s important to test with the customer’s phone. Once an
issue with the USB cable, USB port and USB hub (if equipped) has been ruled out, there’s a good possibility the issue
lies with the customers phone or the phone’s iOS software.

Technical Tips
Before replacing any parts, follow these steps:
1. Restore “Factory Settings” in the radio.
2. Delete all vehicle profiles from the CarPlay app settings on the customer’s phone (this is found under the
General Settings menu on the phone).
3. Ensure the customer’s phone is at the latest iOS software level.
4. Restart the customer’s phone.
5. Lock the vehicle with the key. Move the key away from the vehicle so it is not picked up by any KESSY
antenna. Wait up to 2 hours to allow the bus to go sleep before testing connection again.
6. Inform the customer that when disconnecting the phone from the USB cable, the best practice is to select the
“Disconnect” icon from the main AppConnect screen.
iOS software can be inconsistent. Following these steps, especially restarting the phone, every once in a while will
ensure a more consistent connection.
