Hi,
The SD card in my NUVI 1450LMT is 16GB in size with slightly over 2GB used. It is formatted FAT32. I have used it successfully to update maps onto 7 or 8 times. Tonight when I connected the Nuvi for the latest updates it appears to have competed the software update but then says it can't find the card to start the actual ma update. I am able to see and browse the internal HD and the SD card in the MACs Finder. Any ideas what I should try next?
Thanks,
Jim
