Hello catymag, is there a way to know what software was used to unlock a map?

I ask because I downloaded a Europe map (CN Europe NT 2015.20 by mafozi) and it doesn't work with firmware 4.50 on a Nuvi 55

Can it be re-unlocked with the latest gimgunlock+mapsigpatch? or Do I need the original locked map?

Thanks...
