Carplay issues after IOS 26 installation

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution!

Was/Is your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

If you're still having trouble with your car's audio system using CarPlay or Bluetooth, try the Aux cable. To get it fixed, there are two options:

1. Take your car to a reputable car dealer or car audio specialist. They have experienced technicians who can diagnose the problem with the Aux cable. This could be a loose connection, a faulty cable itself, or an issue with the system's Aux port. They'll be able to repair the issue or recommend a replacement cable if needed.
2. Consult your car's infotainment system manuals. These manuals often include troubleshooting sections that might address common Aux cable problems. You might find instructions for resetting the system, cleaning the Aux port, or confirming the cable's compatibility.

Before taking your car to a dealer, it's always a good idea to check the manuals first. This can sometimes save you time and money if it's a simple fix you can handle yourself. However, if the manuals don't offer a solution, or you're uncomfortable tinkering with the system, then a car audio specialist is the way to go.
