I recently upgraded my phone from a Galaxy S5 to a Note 8. I kept my old S5 to use as a offline music player at work using Slacker Radio. It is working great. After doing some resesrch l learned that l could also use Google Maps offline by downloading maps to the phone while on my home wifi and then using the phone offline to navigate on my street bike. The last 2 weekends l have been practicing and l am amazed at how well it works. I am looking for others who have a similar setup to share ideas and tips/tricks. Here is my first question. Is it possible to record a track or GPX file while riding a loop to share with other ridiers while navigating offline? Anybody else using this type of setup?
