Magellan Mapsource questions in GPS technology and devices Posted February 14, 2008 · Edited February 14, 2008 by sanramonhunter Sold my 60csx and was planning on buying a Colorado, but decided to wait for them to get the unit working better before I purchased. So I got a used Magellan Meridian Color on Craigslist to tide me over for a few months. Figured it would be Fun to play with a different companies unit for awhile. But I need some maps. I know the Garmin scheme on maps and serial #'s but not quite sure on magellan. From what I can gather When you create the map tiles you have to specify the S/N of the unit it will be used in, and it will only work in that unit. Does that mean that as long as I have the disks I can put maps on the unit. Is this true for topo and Direct route? Is it true for all version of mapsend topo? I tried "asking maggie" on the magellan site, what a joke, it came back with a list of 48 "possible" answers to my question. Anyways any help is appreciated. Thanks.
