Mine automatically receives calls in hands free. Only time I have seen something similar to what you are describing is if I initiate a call on the phone itself rather than using hands free then it asks me if I want to transfer to hands free.
I just realized thats what it is. If the call is initiated from phone it does that. I don’t think that’s the case with any car including the Ghibli I had before this Levante. Most cars just pick up on Hands Free as soon as Bluetooth connection is made.
