Iphone 16 app slowness and connection issues

I've got an iphone 16 pro max and am having issue with extremely slow app loading and connecting to apple car play. The phone, the apps and the car are updated to current versions. When I open amazon app it will take at least 1 min or longer to load. Doesn't matter if I am on wifi or not. In my car 50% of the time it will take up to 5 minutes for the phone to connect to apple car play. I have xfinity cell service. Is this on their end? Not sure what else to try. Phone is only 2 months old.

iPhone 16 Pro Max, iOS 18

If CarPlay doesn't detect your iPhone, make sure CarPlay isn't restricted. Go to Settings > Screen Time > Content & Privacy Restrictions. If Content & Privacy Restrictions are turned on, tap Allowed Apps and make sure CarPlay is enabled. Go to Settings > General > CarPlay, tap your car, and then tap Forget This Car.

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.
