I have a standard serial cable for the etrex. I also have an rs232-usb cable. I have installed the driver for the rs232-usb cable.
Iam using Walkhighlands Route Planner. I have installed the Garmin PlugIn, an interface between Safari and the etrex, but I cannot transfer files to the GPS.
I can do the equivalent on my office's PC.
I would love to hear from you if you know what I'm doing wrong!
Thanks
