Kudos catymag and neil!!

I want to have the file into just one file. Thus.. is mapsource the only way to combine or edit the map? The 2 Seperate files is a good idea too, I know.. then I have a question in regards to Post 2 as suggested by Neil. There is a southern US and Mexico... Are the southern States covered in the 49 States maps?

Also, The gmapprom file, is that replacable or should I leave as is? Because when i look into the maps in the device itself.. it does still show the 201.20 map which i'm assuming is this gmapprom file. I knw the file is a pre-install that came with the device as well so if one of you great guys can clarify for me?

As well, sNeil, since you told me that the gmap3d is not being used, do i leave that alone in the device or should I remove it to open up more room on the device?
