I have seen a larger JCV file that some units get with the 2014.10 map D/L, JCV File D319090A.JCV (453,916), but I also see in the JCV folder an UNL file.

I have never seen an Unlock file for a JCV.

Can it be "unlocked" with gimunlock or does is there another method to use ?

I have a 3490 and was not given this Larger JCV file in the normal Garmin D/L with the 2014.10 map, but may want to use it.

So.... how am I able to utilize it on my 3490 if it's "locked" ?
