I'm a little confused here. Is the One time navigation package that came with my car different than the subscription service? I can't really find anything that would indicate they're two separate services.

 

Yes, separate things. The subscription service is for some of the value-added services around online POIs etc. If you don't get the subscription you still have navigation, but you won't be able to do an online search for a destination for example or find parking options etc. If you click on Details it shows what it includes.
