Easiest way to see which JCV file is applicable to your unit is to look at the version for your older map and match the file numbers closest to it. e.g. If your device used D3060110A.JCV for 2014.20 of NA, it will use D3060120A.JCV with this version. It is also sometimes ok to use other files if the resolution matches but not always, for instance the 212*234 resolution file D3836070A is exclusively for x0/x2/x4 nuvis and SP on phones and cannot be used on other nuvi models which use 212*234 such as 2xxx series [or vice versa of course] because of differing encryption.
