IME the iPhone works normally, but if you have a navigation app running a route that app turns into a list of the next steps with no options to view a map, add a stop, or manipulate anything. It's really frustrating for us when, e.g. we have the route to the final destination on screen but the passenger wants to look for a place to stop and eat. They either have to use the car touchscreen (intended for the driver and limiting for someone who can give it full attention) or juggle multiple maps apps or phones.
