Which specific file do i need to get JCV running?

I put the 2014.10 map on it, and it works, but does not show JCV. .....
I suppose you mean you put the CNNT 2014.10 [non-unicode] on it. If so, unfortunately you wont find a x0/x2 JCV file for that, Garmin doesn't make one. The EU Unicode 2014.10 is the one that Garmin puts as OEM on the x0/x2 series. There is a jcv available for it, D3589080A.JCV available in Post #1 of [Only registered and activated users can see links. ]. I'd suggest dl that map and it's associated jcv file if you want to have JC Views.
