As I have discovered, my Etrex 30 won't alarm when approaching waypoints (and I'm not very good at regularly checking the screen) I was wondering whether this function could be duplicated on a phone ? I have had a browse, but cannot find anything that fits my requirements.
1. upload a .csv file containing geolocations. 2. app polls through locations and alarms briefly when <30M from any location.
Sounds too simple, suggestions please?
