A user from Longview, Texas in the United States of America.
Open maps were first used by this user when trying to get street data onto a Garmin eTrex 20.
In the process of loading maps on the eTrex 20, some dated text on the wiki was updated to reference an ability to load multiple maps on some Garmin devices. Loading of multiple maps also raised the issue of identifying them on-device - an issue not covered on the wiki at the time. Instructions relative to setting map name and descriptive texts in Garmin .img files were written up so that the map identity is shown in device menus. (Most .img maps listed on this wiki seem to all have internal names of "OSM Street Map", so loading multiple files on a GPS yields a list of maps with the same name.)
The user also own a Garmin Nuvi 205W, but, at the time of this writing, has not loaded open maps on it.
