Don't worry about it - hook up the unit to your PC.
Push the GPX button on any listing page.
Save the file on the unit in the GPS folder - (the unit shows up as a "drive" letter).
Oooops not easy for me. Press GPX button but when I press it comes with a window asking what should Firefox do with this file? If i press save file where does it go? On PC or GPS unit (the only thing showing on my GPS is window with words connected to PC).
I have the same problem. did you solve yours, and then how did you do???
I found that I had to use Internet Explorer or else it would always lock up. Worked well then.....
