Why is it when I try to start the radio the display is showing phone

What is your question?

It just happened today, I might have touch something but my phone is not picking up calls and when I go to menu and go to radio it shows phone and processes in calling. Same thing when I go to different menu

What makes this problem better or worse?

When I could use wireless to talk on the phone

How long has your 2017 Lexus RX350 had this problem?
