Hi Rockirj1,
Do you typically use CarPlay for calls in your vehicle? If so, for help with getting connected test the steps below found in the article here: If you need help with CarPlay - Apple Support
"Make sure that your iPhone has the latest version of iOS. If your iPhone is updated to the latest version of iOS, follow these steps—checking CarPlay after each step:
- Check your connection to your CarPlay stereo:
- If you have a wired connection, try connecting again with a different USB cable to a different USB port if you have one.
- If you have a wireless connection, make sure that Bluetooth is turned on on your iPhone under Settings > Bluetooth. Then go to Settings > Wi-Fi, and make sure that Wi-Fi is also turned on. Tap the CarPlay network, and check that Auto-Join is turned on.
- If CarPlay doesn't activate automatically, look for the CarPlay logo on your car's display and select it.
- Restart your iPhone and your car.
- Make sure that Siri is on.
- If your iPhone isn't detected by CarPlay, make sure that CarPlay isn't restricted. Go to Settings > Screen Time > Content & Privacy Restrictions. If Content & Privacy Restrictions is on, tap Allowed Apps, and make sure that CarPlay is enabled.
- Go to Settings > General > CarPlay, tap your car, then tap Forget This Car. Then set up CarPlay again.
- Make sure that your CarPlay stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information."
Additionally, Uconnect is a different service provided from your car manufacturer. You can check your vehicle to see if all firmware on that end is updated and view additional information from the Uconnect FAQ page here: Frequently Asked Questions - Uconnect® System FAQ
You can also connect a different Bluetooth device or speaker to see if you have any issues with calls. If not, the problem is likely with the vehicle. There's also helpful information and steps to test here: How to connect your iPhone, iPad, or iPod touch to your car - Apple Support
Cheers.
