I jumped off the technology train about 7 or 8 years ago. At that point I had (have) an e-trex. I would connect it to a laptop with topo software to make trail maps. It was cumbersome to say the least. I now have a state of the art iPhone 4s! I would like to track my route, then get it on to a PC and print a map. Can this done? What app do I need? How does it get to the PC, don't say majic! I,d like to put in a topo format. Any help appreciated, use small words.
