Navigation and making a phone call

Every time I'm using navigation and I get a phone call via Bluetooth it leaves the navigation screen and goes to the phone screen. Is there a way that I can somehow see the directions while that switch happens?

I constantly miss directions because the map is no longer on the screen. I know you can leave the audio on but that is not enough.

Ideas?

 

Yep, that's the issue - I know that I can hit the app button and go back to the map screen, but sometimes when I'm making or receiving the call I will lose the screen and miss the turn.

Keeping the sound on during a call is likewise cumbersome, it blocks out the call.

My BMW has a split screen that you can still see the map in while making a call. That's nice, and this is a hassle!
