AMAZING - as good as Garmin and $380 cheaper!!!

Iphone GPS chip is pretty comparable to the handheld gps units ive had (Garmin) in california mountains with no cell reception, so I see no advantage to using a separate GPS unit when you ready have a smartphone you will be carrying, and which has a much, much better screen. Gaia enables this with a very good interface and great topo maps, and you spend $20 instead of $400+ (because of Garmins monopoly in the standalone gps space). Wonderful product and what tech innovation is all about!
