Garmin units can not display images, only vectors prepared in Garmin's map format.
http://cgpsmapper.com/en/tool.htm and tools based off it, can prepare data in the format. I've experimented a little with coverting OpenStreetMap data in Garmin, with cgpsmapper. http://wiki.openstreetmap.org/index.php/OSM_Map_On_Garmin There are OSM based projects to produce outdoors maps. http://www.free-map.org.uk/ -Mikel ----- Original Message ---- From: Reid Priedhorsky <[EMAIL PROTECTED]> To: [email protected] Sent: Sunday, September 10, 2006 10:10:28 PM Subject: [Geowanking] Uploading my own maps to a handheld GPS? Dear geowankers, So, I'm thinking seriously about buying a GPS unit. What I want is the following: 1. Cheap 2. Can show me my position on a topo map I looked a little at the Garmin units and they want $120 for the topo maps and don't even support what I really want (24k USGS topos of obscure places). Georeferenced image files of the topos seem pretty easy to get, so it seems like I should be able to upload those into the GPS unit. Do any support this? Any pointers to websites on this topic? Other thoughts? Linux is preferable, but Windows is OK, and I'm willing to jump through a fair number of hoops and/or user unfriendliness. Thanks very much for any help.
