Correct path:
On unit - x:/.System/JCV/D3589120A.jcv
or
On microSD - x:/Garmin/JCV/D3589120A.jcv
If you've placed the file correctly, back up your favorites if you wish to keep them and then hard-reset the unit by holding the lower right-hand corner of the screen then turn it on. A reset or clearing nonvol memory will often fix strange behavior.
