He was making a joke. He couldn't get TH JCV to work on his CHN nuvi 1455, so he put [Only registered and activated users can see links. ] with Thai Streetmaps v12.1 & its jcv file on his iPhone instead.

- How do we check which JCV is meant for which map?
For a country with different maps, can map A uses map B's JCV by just renaming ?
JCV files are specific for each map, i.e. each map series and version. The jcv files are issued with each map release if they are available for that map. You can't swap jcv files between different maps by renaming or any other way.
