I'm working through the really great features on the 520. One feature I've unsuccessfully mastered is how to allow others i.e. friend or friends to follow my ride in real time. I believe it is possible and it's one of the reasons I purchased this model. As you offer you valuable response, please keep in mind I'm still learning and perhaps one day, I'll be able to offer you some much needed help!
Thanks SO much for your attention to this important detail for me and for making it important to you!!!
