I believe it is a vehicle tracking device that allows the dealer/lender to shit off the vehicles ignition if you fall behind on payments. I've known a few people to have this happen to them, and you can look it up it is a real thing. I don't know if they only do it on "higher risk borrowers", or...
The built in navigation, not the subscription, would be nice whenever I am camping in the mountains without cell service and need to find my way home. But you know paying more money for less features works too I guess
Just cancel your order through Ford. If you don't have a vin then it should just go away. If you tell the dealer to cancel your order, then they would probably keep it. Unscheduled with no vin, just call Ford and cancel.
