I'm not actually assuming it only happens for one town. I'd assume it would be broader than that. I don't really think it matters much how it happens, though, does it?
Even if all that happened were a widespread cellular outage, it's unlikely I'd have that region downloaded such that I could still search for whatever address I needed. Locals very well might, even accidentally in their caches, which might let us generate directions to somewhere I could get a map...though it would make it harder to look up the phone number to verify whether such a place sells maps.
It's not necessarily completely unsolvable. It's just a lot harder than it would be if other people still cared about map navigation as much as I did.
