Translation to EN for downgrade:
Spoiler: Click
If you don't follow the guide precisely the plotter will generate a GarminDevice.xml file on the card and it'll remain at the higher fw. After the downgrade, upgrade again directly to latest firmware. As catymag said, you must extract twice. First extract 'ChartplottersUpdatewithSDcard_20140306.exe', then extract 'program_card.exe' and look inside folder 'Root' to find folder 'Garmin'. Copy the relevant file 'gupdate.cgd' into a Garmin folder you've created in the root of the card [x:\Garmin\gupdate.gcd].
