Hey Dave, yes I believe they basically have emulated your GPS and incorporated it into the Ipad.......I have been comparing the features and they appear to be about the same.
Beacher....I have been playing with routes through and around Yosemite with booth my Rand Mcnally app, and the Good Sam RV route planner on line......i can't get it to give any kind of mountainous warning...I guess you either just have to be familiar with the terrain, or ask advice from others.....as a newb Class A driver, not sure I would feel comfortable on that road right now !!
