SO in 2.1 if I was in NAV mode and a call came in the screen would switch to call mode. when I hung up the screen would switch back to NAV mode. In 2.2 I have discovered that after answering a call the phone does not switch back to NAV mode. It went to the contact info. Touching the car home did not bring me back to the current navigation. Instead it was as if NAV had never been invoked. Anybody else see this yet?
