Q: Can anyone tell me how to turn off the annoying bong noise i get when i approach junctions whilst using maps in carplay and on a call? it comes through so loud that it hurts the ears of the person on the other end of the call

I have carplay capability on my car, whilst for the most part this is great (although the maps app isnt as good as google maps). I have muted the voice over, but when i am outside of Apple Maps (i.e. its running in the background) I get a loud 'bong' noise when the app sets a new direction. I would very much like to turn this off somehow. Can anyone help please?
