Any experience with any of these, or others?


I've had 'limited' experience using Tom Tom's software but only on their street gps units (not on the ipod). Based on this, my opinion is I like their software & interface far more than I did the Garmin, Mio or Magellan alternatives I tried.

I did find this since I've also been looking for a solution (except for the Ipad instead of the Iphone)... http://www.engadget.com/2010/04/09/iphone-navigation-shootout/

One thing I'll point out is that these programs are primarily for street navigation and not so much for the trail. Off road navigation is possible but the Iphone gps chip isn't as sensitive partially relying on cell tower triangulation to improve it's accuracy. In my research the 'preferred' gps chipset is the SirfStar III chipset.

Also, I don't know of specific topo navigation programs for the Iphone. I'm sure they exist. Just haven't looked for them. <img src="/forums/images/graemlins/kewl.gif" alt="" />
