Hi all, got a question..... I'm thinking of getting an Ipad mini, I have an Ipad, Iphone already so I'm an Apple junkie lol!!! The reason I want the mini is for a large screen GPS and music device for my car. I am on the older side and find my portable GPS is just not big enough, the mini is perfect. Now for my question. Im getting the GPS, glonass Wi Fi cellular version. Can anyone tell me do I need to use my data plan to use this unit as a GPs/nav system? I thought with the GPS built in, with the right app it would behave as a regular GPS without the need to use my data. If this is true, would the built in map app work or would I need to purchase another app, if so what do you suggest. I sure hope I can make this work, the mini seems to be my perfect solution. thanks in advance folks.
