i not sure i asked here before or not. but suddenly my cousin said samsung galaxy tab wifi also can use GPS without data plan. He say as long as got GPS receiver then can use GPS, cause he say like all papago, or garmin and so on, all also no need data plan 1 ma.

But i dunno why i always keep on thinking that without data plan, then cannot have GPS navigation.

So it is really can just get a wifi edition and still able to use GPS navigation without data plan?
