I download the files from the links below,
the date of the map files are 12/8/2008
the file Destinator's version is 188.8.131.52
I don't know whether this is the last 2009 update.
Quote from willwgp from SD :
Here lies the Omnitech's original files that commonly come with the GPS unit. Includes all the maps also. It is about 1.25 GB unzipped. This will fit on a 2 GB SD card, but if you take out some of the map folders (suggestions: Puerto Rico, Canada, CA and WA [unless you live there of course], Hawaii, Alaska) it will fit on a 1GB SD card! Just unzip this and put it right onto your SD card and you should be ready!
Part 1 (300mb)
Part 2 (300mb)
Part 3 (243mb)
This is in 7zip format, you will need to download 7-Zip or compatible to unzip this. Thanks, and travel onward!
