recently updated my nuvi 1450 and found out that its HD will now only be able to hold the lower 49 states NE only, so updated maps on those and then i proceeded to buy a micro sd to add all the other maps, but don't know how, tried plugging my nuvi and it says that my maps are current and no updates yet ( it pertains to the lower 49 states NE ) that I updated recently.
