Unfortunately, I don't know why mine (etrex 30) cannot be seen by any of the computer I have got at home....like plugging absolutely nothing...
not sure if it is the appropriate time to have a massive reset (Which I did before) as I am leaving on Sunday for a 2 weeks across Europe..
So I suspect that I can't do with my etrex 30...
Can you do that with your etrex 30x?
I might ending buying one.
