hello there,
i already have a gmapsupp file in my nuvi 215W which is a east africa map now i tried copying the nigeria map file & given name as gmapsupp1 but it is not showing in the gps
even i unlocked the mapsource version & transferred to the nuvi but while doing so the east africa map disappears as it is overwritten by new file of nigeria map.
pls. help how can i have both map together.
thanking you in advance,
