I tend to download GPS tracks onto my eTrex 20 from organisers of events, rather than plot my own. However, I've noticed that I don't get the audible beeps for an upcoming turn, even though the device is set to use them. (it's a function that I would find very useful especially when tired).
In order to get this function, do I need to 'plot my own' as it were - and if I do, should this be in the form of a route or a track, or would both give me the 'beep'.
Thank you
