As Marc said Northwest Topo is just a maps set. Not even a program, and definitely not a gpx file. You need to use some shell programs like Garmin BaseCamp (which is free and supposed to come with your watch on CD / DVD) to view specific maps and gps tracks on that maps. You also will use this program to create points for your watch to use it for navigation. And lastly may be it will make sense for you to learn how to use GPS to get advantage of this tool....
