I know this question was asked somewhere before but things are changing quickly... Has anyone used iPhone (from AT&T) as GPS in Croatia / Bosnia & Herzegovina? Which app did you use? Can I use dedicated GPS app without mobile signal / internet data plan/charges? (I will turn off Data Roaming to avoid expensive charges...)
For example, Nav4D ( http://bit.ly/hESfUX ) sells Croatia ($24.99) and FAQ says "Does Nav4D requires an Internet connection to be used? / No, Nav4D uses offline maps so it can be used without an Internet connection ( http://bit.ly/fPTGcH ).
Thank you for your help!
