To add a favorite destination, take the following steps:
1) Go to settings
2) Tap on "Favorite Places"
3) To the right of the search results there is a star icon - tap it to add an address to your favorites.
If you have previously traveled to a destination you wish to add to your favorites, you can do so by simply tapping on the star icon next to the interested address under previous pickups.
When a favorite address is added, the icon color will change to gold. You can remove favorite destinations under the Favorites tab by simply tapping on the gold star. You can also designate your home and work locations.
