Can anyone tell me why, when using the gps feature on samsung ominia sch-910 it goes thru the phone com port and baud rate? Why doesn't the gps work like a tom tom or garmin without a phone connection? Also when using the gps feature cause it goes thru the phone am I getting charged for it? I do not have Verizon VZnavigation.
Any explanation wouild be helpful, thanks, Sam910
