You would need a mobile navigation app for this that allows you to import routes from GPS files, which you can download from plotaroute.com. We don't have one of our own but there are a number in the app stores.
Hi, I ploted a route online for cycling and would like to download it to my cell phone. Is this possible? If so, how do I do it? Also, once in my phone does it give audio commands while I am riding? (upcoming turns, etc). I am not tech savvy so the simpler explanation the better. Thanks!!
