When troubleshooting CarPlay, start by checking the connection to your Cadillac CT6’s infotainment system.
There are two ways that your iPhone can connect to your Cadillac CT6’s infotainment system: either via USB (wired) or Bluetooth (wireless connection). Which connection type your car uses will depend on the model year and what entertainment options are equipped.

- Iphone with home button– If your iPhone has a home button, slide your thumb onto the screen from the home button. It’ll bring up a quick menu. You’re looking for the Bluetooth symbol. It’ll be the color blue. If it’s gray, turn it on by touching it and give your phone a second to connect to your CT6.
- No home button– If your phone has no home button, slide your tray down from the top. On the top right, swipe your thumb past the battery symbol, and the quick menu tray will drop. Verify the Bluetooth symbol is blue. If it’s not, turn it on.
- Settings (works for all iPhones)– Open settings and look for the Bluetooth options. It’ll say if it’s on right there in the main menu. If it’s not, click “Bluetooth” and toggle it on. If you’ve set up CarPlay on your CT6 before, it should automatically reconnect.
Once you’ve verified that Bluetooth is working on the iPhone, check if your Cadillac CT6 is on the list of possible devices that it can connect to:
Settings → Bluetooth
If you don’t see your Cadillac CT6 as a possible connection option, open your car’s Bluetooth settings. You should see your phone. Tap it to connect. If it doesn’t connect or you don’t see your phone as an option, turn your infotainment system’s Bluetooth off and on again.
After checking the connection, try connecting to a different iPhone. If that iPhone works, you know there’s an issue with your iPhone. “Forget” your vehicle and reconnect your iPhone. Jump to section 5 for exactly how to do that.

CarPlay is just an extension of your iPhone on your Cadillac CT6’s large infotainment screen. It simplifies the interface in order to reduce the amount of time you need to look at down from the road. Outside of the connection, most of the other issues will be solved on the phone itself.
Any iPhone from the iPhone 5 (released in 2012) and later with the latest version of iOS will work with Apple CarPlay.
While iPhone has been supporting CarPlay for years, it’s always a good idea to upgrade to the latest version of iOS if you’re having connection issues.
