Please help! I leave in two days. My friend has lent me her Garmin Nuvi 260 for an upcoming trip to Nicaragua. She said that she had paid extra for a lifetime update on her maps. This is supposed to be covered worldwide. She did an update last night. But once I get to the country is there anything else I need to do? Does it automatically register as being in Nicaragua or do I need to do something in the settings? Thanks!
