My Iphone 7 will pair with my Cadillac Cue. It will accept/make phone calls. It will NOT alert me of text messages. I've unpaired it, turned off bluetooth, forgot the network and repaired it again. Nothing seems to work. Suggestions?

Hello Mrs.Dunn,
Thanks for asking about your connection between your iPhone 7 and your car. Depending on how you are connecting, there are a few things to check. I will be happy to help.
If you are using CarPlay, please check this help article: Set up CarPlay with your iPhone.
If you are using Bluetooth or a USB cable, please check this help article: Get help connecting your iPhone, iPad, or iPod touch with your car stereo.
In both articles, there is a section that has you check for firmware updates for your car stereo. This may be required to allow the stereo to work with the iPhone 7 or with iOS 10. You can check the manual provided with the car for help with that.
Thanks again and have a great rest of your day.

iPhone devices

• Pair your iPhone with the system
• On your phone, select settings>notifications>messages. Make sure that “Allow Notifications” and “Show On Lock Screen” are both selected on.
• On your phone, within the Bluetooth SETTINGS menu, select the “i” icon next to your vehicle name in the device list and enable SHOW NOTIFICATIONS
• The feature will be enabled on your next ignition cycle (wait at least 3 minutes after engine shut off)

Note: Your device should remember your notification preferences when it reconnects in the future.

Text Message Alert functionality varies by phone. The following functionality is specific to some iPhone devices:

• Text messages CANNOT be responded to using the radio system for iPhone devices; they can only be received
• Only text messages received during the current drive cycle are accessible using the radio system
• If the user’s phone is currently showing an open text message screen/app, the user may not receive an alert for new messages in the active conversation through the radio system
• iPhone’s have to have iOS6 or later version so that incoming messages can be displayed on the car’s dashboard and/or read aloud by the car’s computerized voice.
