Apple CarPlay has no sound for Apple Maps, Google Maps and Cell Phone calls. Music ausio is fine

My phones used with the car stereo/Apple CarPlay are both iPhone 13's with IOS V16.6. My car stereo is a Boss BE7ACP and I am connected via a USB cable.

I have verified the cable is good.

In the Boss settings I have defined the default volume levels of music, navigation and phone call audio. I set it at 30 for all three.

I have verified in the navigation apps that nothing is muted and sound is enabled. I have done that in the app on my phone and in the app while using Apple CarPlay.

I get music audio using Spotify and SiriusXM.

When using navigation it dims the music audio to give directions but there is no audio of directions.

When making a cell phone call or reviewing a text message, it stops the music audio but there is no cell phone audio of either spoken word or reading of a text message.

I have browsed the questions in the Community but have not found a solution that helps me. Does anyone have any thoughts/solutions on this?
