CarPlay - new car not working properly

Hi,

the CarPlay (wireless) is not working properly in my new car (BMW 5).

Here are some symptoms that are appearing:

* connecting to CarPlay is very slow and takes up to a few minutes

* playing music stutters, regardless whether it is Apple Music or Spotify, leaving a very unpleasant experience

* CarPlay is rebooting in the middle of a call, leaving a black screen and no communication

* tapping an icon on CarPlay is taking a few seconds up to 10 to 20 seconds before it responds

* incoming calls take a long time before they are displayed

* outgoing calls with Siri are not showing properly. The display stays black.

Rebooting and reconnecting the iPhone doesn't help. The same symptoms are appearing over and over...

The iPhone is a 6s and the 5s of my wife has the same symptoms. Both have the latest iOS installed on it.

At BMW, they state that it is an iOS problem...

Is someone having similar issues? Does anyone has a solution for this?

Thanks in advance!

Best regards,

Jorn
