The Trail app seems to have been discontinued all together. If you didn't already have it on your phone, you can't get it via the App stores any longer.
That said, even when it was working, it required a full sized, qualified Bronco to work.
I'd recommend OnX Offroad, Gaia, Trails Offroad, or one of the other apps.
Didnāt even realize they took it off of app stores. Probably because its such an underwhelming app, if you dont have it youāre not missing out on much. It rarely works and honestly makes things more annoying than they should be. Really nice Ford just decided to do this under the radar.
