There are many apps like CoPilot live. I use it on my Acer Tablet, which does not use a cell phone plan only wifi. wifi is only needed for maps. CoPilot live downloads the maps so the only connection to wifi needed would be to download the maps and program. There should be a version for Apple. I also have a Verizons and ATt wifi card, I can use, and CoPilot live takes very little off my plan.
