So after much consultation with other members of this forum, issues with programs and personal effort, I have another issue with generating route-able map data for newer and older model Nuvi units.

I am currently using a route-able version of cGPSmapper, Sendmap20, SDLock and GPSMapEdit to generate mapping data for a Nuvi 700 series. And it works great. BUT, when I try to put the same data on a Nuvi 1000 series, after editing the information before generating data, it won't read my data. So I tried a new direction to solve my new issue.
After asking questions and getting feedback I downloaded Mapsource, MapsetToolkit, and another version of cgpsmapper (for solution issues).
"Now" when I try to use the MapsetToolkit to change my .img file to a .tbd file, to open with Mapsource, it tells me that I have to use the GMapTool program, so I then downloaded gmaptool. Now it tells me I have a locked map so checked my source data against the new file I'm trying to create. I matched the FID thinking that maybe this could be the issue but to no avail it won't budge.
Please, I know this looks like a catastrophe, so I can try to clarify more, but can someone help me untie this knot I've created for myself.
Feeling kind of at wits end so to speak. I believe I am over complicating the heck out of this.
Thanks in advance.
