Hello everyone, see if someone can help me.
I have a Garmin Nuvi 2547LM with maps of Europe installed now want to put the maps of North America but I always get an error that says: "Unable to unblock the maps".
I've tried everything, I put the unlocked in SD and internal memory as gmapsupp file, but I always jumps the same error.
I have read several threads in this forum but my English is not good and I do not see where the problem is.
Please grateful if someone could guide me and if there is someone who speaks Spanish would be great.
Thank you very much.
