sigh... let's take this from the top:
1) Are you still using the original serial cable that came with your eTrex H, or by some chance did you change to a serial/USB cable along the way?
2) Does your computer have a physical serial port into which you can plug the cable? Does it have MORE than one serial port?
3) What operating system does your computer use?
Once we have the answers to those questions, perhaps we can get you connected again.
Sorry Ecanderson, I know this has come up more than it's fair share of times. I will post my answers but I will also look around again. The search function is a little strange on here it won't allow me to search for any word less than 5 characters which returns errors when I type in something like "etrex H". anyways;
1) I switched to the sierial/USB cable, yes I got the driver that I supposedly needed. It came with the cable but I also tried a few different ones from Garmin and Microsoft.
2) I have multiple serial ports.
3) I have windows XP SP 2, but I can update to SP 3 if needed.
