Error 105


Impossible to send a destination to the onboard navigation system. Shows error code 105...Problem exists since last 2 updates.

Good but....


Own and edge, mkx and now xt5...xt5 is the only one that we cannot program a auto start...when you are at airport for a week you cannot remote start as it goes to sleep. Even my wife ford escape does have a day and time where it will wake up from sleep. Apple watch app is the first that i have but keep getting red phone like if i am loosing connection even 2 inch neighbor owns a hyundai it their app on the watch works like a charm. Again, nice app but would need a little plus...especially when it is Cadillac



L’application fonctionne super bien depuis la nouvelle mise à jour!
