I'm still in the dedicated GPS camp for my primary but we have added the Free version of Copilot to my wife's iPad for checking routes and planning. Also gives a second opinion on routes. She use to juggle paper maps to verify GPS routs or find things along the way and it took forever to find us on the map to start looking, now it comes up and says where we are and she can start immediately. With all North America downloaded off free WiFi we don't use any data while using it.
