because I was using Navtweak 2.6, I actually had to open the Lng_American file in a hex editor to make the change to the file description to Lng_Espagnol and then use CRC24 to edit the checksum so that I could reimport it into the Navboot as Lng_Espagnol without navboot complaining. I also edited the espanol map files to the american and everything is working great. I love this site!!!
