Apple CarPlay phone problems stock head unit

So on my 2020 SR5 it has the stock head unit with Nav. when I hook my iPhone up to it lately phone calls are bad. Like I hear static and the head unit display hangs up.

Hang up as in the screen it normally shows a timer of how long the call is, mine gets stuck showing call placing.

Additionally the call quality is bad. Clicky and such.

I’ve tried it on brand new iPhone 16 with latest update, brand new Anker usb cable and the head unit says it doesn’t need a software update.

The only thing I haven’t replaced is the part where it plugs in the truck.

Other functions such as Apple Maps and Audible seem to work fine. With some lag.

is there a fix other than replacing the head unit
