What i'm doing wrong
I would re-download it and attempt again. Corrupt file maybe as most are uncompressed/not archived as a download. (ie raw .jcv file, not as a .rar or .zip)

Also, where are you placing it? SD card or on the unit itself? Whether SD or unit the JCV should be in \Garmin\JCV

Too, check that you don't inadvertently have two JCV belonging to the same mapset. I don't think that works and might explain the blank screen. Not 100% sure though.
