Thread: TOPO U.S. 2008 v2.01 100K (ALL-IN-ONE Garmin OEM IMG with FULL Coverage)

It won't work at all because of a file size limitation.
Garmin GPS units use a FAT32 file system that has a 4 GB per img file size limit.
Garmin (and all other GPSR manuacturers) use FAT32 because it's a known standard and compatible on Mac OSX, Linux and Windows.
Combining this map img with the full latest CNNA img (2012.10) would result in an img file that's greater than 4GB.
ALL img files MUST be less than 4 GB or the device can not read it.
