I'm thinking about getting a samsung galaxy player and being able to use maps fully without a data plan is going to be the deciding factor. it has a built in gps but i dont know if that matters with maps since i think its internet based. so my question is will i be able to fully use maps even though i dont have data but do have a gps receiver? and if i can will i be able to use it for transit lines? any help would be great and thank you for your time.
