I had this on the bmw, the subscription was for 3 years. The period of the lease, I extended the lease, and the live Sat nav expired. No problem, just use waze or google maps, which are a lot better, IMHO, the location tracking of the vehicle still works, but I also have an airtag, hidden away, so it wouldn’t be the end of the world, although the on- board app, relays petrol, locking status etc. Check with motobility. As I think the subs should last the whole lease, but it’s the way of the world now, to rinse you through subscriptions. Just watch the ep, Common people on the Black mirror series on Netflix, for the future.
