As for now the following changes where made:
– Blue navigation path
– Apple style map icons
– New background and road colors like on your iPhone (Background only in cabin, not in Route Advisor)
– Added Siri voice navigation (only english and german) with metric or imperial units

To get Siri voice navigation, you need to select the desired language in the audio settings.
Compatibility update for game version 1.52.x
