Hey all, I am a small keelboat sailor on Lake Ontario (Canada)

I am planning on doing more cruising these next few years, and thought planning or following my progress in the trip would be fun, and informitive.

I have a G3/800 ibook I want to use as my onboard machine, because of size, battery consumption and I have it sitting around.

I have a yellow Etrex, which I have used as my onboard GPS for years, it has the garmin serial.

I bought one of the inexpensive prolific chip usb to serial cables... but on mac or pc I have yet to get communications to work.. (on one pc direct with serial cable only)

I have updated the etrex on the pc before, so, the question is.. usb-serial is too cheap?? I dont have another serial device to try..

OR maybe the etrex is not usable for realtime???

Does anyone know?

thanks

James
