Deleting previous destinations is relatively straightforward, once you know what the trick is!
Guide1. Place your finger on the no longer required destination within the Navigation function on your Infotainment screen:
2. Instantly swipe your finger to the left and this movement will reveal an option with the Delete function highlighted.
3. Press the Delete option and Voila, the obsolete destination will be gone from your screen forever.
It is imperative that you swipe the obsolete destination straightaway or the system will immediately start calculating a route.
I hope this helps.
