You can use the Topo USA program included with the DeLorme PN-60 to import the waypoints, then export the waypoint from Topo USA to GPX format.

The Garmin will them be able to import the GPX file.

Let's keep the discussion on GPS

L-)

Yes, indeed. There are plenty of other places to discuss that. It has been a long time since I've had to moderate threads or users and I'd like to keep it going that way. :)

@Ralph2689 If you go to this link that should do the trick for you.

Wow, I wrote that article nine years ago, but didn't remember the answer myself.

This thread is relevant:

I know of at least one government agency that has lots of integrated GPS devices in remote locations that were found susceptible to pretty much the exact same bug. Long story short, even when the original manufacturer wrote a firmware fix they were a massive pain to update not only because of their remote location, but because the government typically doesn't give employees administrative access to their computer, which they discovered was required to run the firmware update.
