Here is a instructable to build a datacable to connect your Garmin with the PC via USB. 
I made this for my sister.
The idea is from:
http://www.jens-seiler.de/etrex/datenkabel.html
There you can also find other instructions to build a datcable- but just for serial connection.

The solution at the named page wasnt good enough for me. I want to have a better conection.


Step 1: Disassembly

look at the  intructable from : zzpza
Garmin eTrex H Dissassembly

or:

be carefull while demounting the black rubber around your garmin. it rips easily.
after that you have to remove the tabe.

with a sharp knife you can easily open the cover.

unplug the plug on the pcb in the gramin.

Step 2: Welding1
