One of my favorite hobbies is going to estate sales. Years ago, I would get the Estate Sale addresses out of a newspaper and then tediously and manually plot a trip. Getting a handheld GPS unit (A Garmin nuvi) changed all that. I could visit an estate sale web site and launch map pages from there. There was a browser plugin called Garmin Communicator that sent the addresses from the map pages directly to the GPS via a USB cable. It was awesome. ☺
Then Google Maps and MapQuest pulled support for the plugin. ☹
So, I wrote a small program to replace the functionality. You paste in addresses (with latitude and longitude) from the map pages and it will create a GPX file that you can send to a USB connected device. Or, you paste in an address and click the button "Get Lat, Lng from Web". I hope someone else finds this useful.
*Update: The suction cup holder of my Garvin failed and the unit dropped and broke. When I plugged the replacement unit into my PC there was no drive letter: Windows considered it a "portable device". The workaround is to set the Garmin to be a storage device in the diagnostic/developer screen:
