I wonder if the download files have been updated to match the version officially released by Garmin on 20/08/2014, or are those who were originally placed by you on 08.01.2014.
You can calculate any checksum for block from word GARMIN to end of both file. Data before word GARMIN is title and do not contain any info except data of creation of file. If it is equal so no difference. It take pair of minutes...
