Offline maps using Ipad 2 - confused
Hello - I hope you can help. I'm about to buy my first Ipad 2 and am planning to get a WiFi only version. However, I'm not sure how good it's going to be for offline maps as I know it doesn't have GPS capability. I'm doing a US road trip soon (Nashville to New Orleans to Memphis) and ideally would want some maps to help me when driving. They don't need to be turn-by-turn navigation (for which GPS is needed), but just a general A to B to C map (of the kind you might map out on mapquest/google maps and print out with directions). Are there any good Ipad map apps for this? (Note: ideally I don't want to prepare screen shots before and then look at them as photos. So it would be good to be able to download maps for all 4 states I'll be passing through on the trip, TN, AL, LA, MS, and then enter our chosen direction on the road - if that's possible!)
Or should I just pay extra and buy the 3G version and then purchase something like MotionX GPS Drive? (I'm not likely to ever use the 3G version for anything else other than the GPS though).
Thank you! :)
