You don't need anything as massive and MapSource to get the waypoints 
and tracks out.    There are at least two freeware utilities that will 
do the the job.   Both of the programs belows are small lightweight 
programs that don't sludge up Windows with "mystery DLLs dumped into the 
Windows system folders or entries in the Windows registry. Either can be 
run directly off a USB stick without a formal install procedure. 


G7toWin will upload/download data to Garmin units, including USB ones 
and is downloadable at:


This program will download tracks, waypoints AND bitmap graphics dumps 
of the display screens of those Garmin units that have them.  It can 
download into numerous of file formats including various proprietary GPS 
formats, plain comma separated text files and Delorme .SAx files 
directly readable by Street Atlas and TopoUSA. 


An alternative is GPS Babel downloadable at:


This open-source utility can both upload/download from variety of GPS 
units,  and can also convert files already on your hard disk between a 
huge  variety of proprietary formats used by various GPS mfrs, mapping 
programs and geocaching websites.
