When searching for POIs , it is important for you to know that you can find "Points of Interest" in the destination entry of the navigation system under "Points of Interest".
When route navigation is active, select whether the POI should be located at the current location, along the route or at the destination and then select the desired category (e.g. "Food and drink", "Accommodation" or "Filling station"). If you then click on one of the suggestions, the route to this POI will be suggested to you in the route navigation.
