Outsmarting Garmin's current.gpx
Yesterday, we took a test ride with Mark and two other bikers up into the Olympic mountains (more on this later). I had loaded some three hundred waypoints into my Garmin Nuvi 360. Sure, I knew that it wouldn't show me the Forest Service roads we took, rather it was an exercise in loading and using waypoints via GPX files.
Now the issue is how to clear out those waypoints without going one-by-one through the 6 click process of deleting them. On some sites people have resorted to simply resetting their devices (as I did myself one time). However, there is a better way.
* Connect the GPS device to the computer
* Open MapSource on the computer
* Load up current.gpx from the GPS device
* Edit the waypoints, etc.
* Do a "Save As" to a different file name on your computer. Be sure to save as a GPX file.
* Disconnect the GPS device and boot it up.
* From the menus, use the "delete all" feature to remove all of your favorites.
* Right now current.gpx on the GPS has nothing in it. This is a good thing.
* Reconnect the GPS to the computer
* Copy the edited GPX file to the GPS into the same directory as current.gpx
* Disconnect the GPS and boot it up. You'll find only your new set of waypoints on the device.
TIP: If you are going to load up a ton of waypoints into your Garmn, it makes sense to save a copy of current.gpx onto your computer beforehand to make reverting that much simpler.
