I am looking for a GPS that will guide me on hikes and travel from point A to point B without loss of signal in remote areas. I have found this accessory for the iPod touch that enables GPS location services. I am looking for other users EXPERIENCE (not opinions) of this accessory and their personal thoughts on using it or other solutions that I can use my iPod as a location/directional device.
My iPod touch is a 3rd gen, however I feel that this is something that would be desired for all gen's (at least for the 4th as well)
