I use the Sync Destinations app on my iPhone to setup "My Points", than shoot it to Sync via the app. Than use the turn by turn directions. I am really impressed on how well it works. Have not used my GPS in a while! The only down side is if you go off-route, it takes it a bit to redo the directions since it has to learn your location and download new directions.
Also use it all the time for weather, finding businesses and news.
