Recently I've been thinking of buying a standalone GPS but it really cost a lot of money and the screen is stupidly small.

So I decided to make my iPad (4th gen) a part time GPS Navigation device when I'm on the road (car holder come later). Besides Waze Social Navigation, is there any GPS Navigation apps that support iPad 4 resolution, less use of data(off9 if possible), has good support & updates, frequent map updates(especially for Malaysia & Singapore) and user friendly?

Thank you
