Thread: Updating a 4 year old NUVI 255W ???

Yes...you are right.But I'm going to update to the latest firmware and try a map over 2Gb.If not support it I'll deselect some countries like you.

This is because both devices support the FAT32 file system, which can accept a file of up to 4GB minus 1 byte in size. Devices older than the 200W in most cases only support FAT16, which limits the map to 2GB minus 1 byte in size.

I did it and really have no problem with recognizing of the whole map which is 3,4Gb (City Navigator Europe 2015.10 NTU). Now I have another problem with this map.I'm not able to find any addresses because my unit does not support unicode maps.I can only find different City but not address.Now I have to wait only NT release.
