Good afternoon. After renovation 5.20(Patch) on 5.30(Patch) my Dakota 20 were not loaded. Except this, Windows XP did not see the navigator as USB-device .Thanks Kanopus, i have looked references and has entered so. Has Connected Dakota to computer, has pressed on button of the cut-in and kept long until Dakota was defined as USB-device. Has Loaded in root file Garmin version 5,20(non Patch) and has started Updater.exe. The Dakota was restored and loaded. Then I have did by FirmwarePatcher 29 versions 5.30 patched, not changing names ("don't change the About page and the firmware version name"), and has updated anew. All were updated.
