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.
