Trying to interpret this:
9. Lifetime Subscription Plan: A "Lifetime Subscription" is one that continues for the life of the receiver equipment. A Lifetime Subscription is not transferable if it is associated with a receiver installed by an automaker......
O.K., so it is the lifetime of the radio. The transfer apparently refers to the transfer of the subscription to a new or different radio, not the transfer of the vehicle to a new owner.
Does that mean that if the vehicle is sold, the new buyer has the continued benefit of the subscription? Would that not be a "premium option" of value on the sale of the vehicle?
