Hi I have the Nuvi 700 and I bought a 5 gig storage chip for it. My question is simple: How does the NuVi utilize the extra storage or integrate it into it's limited amount of storage? I mean why would Garmin offer updates for a unit that can't store them? Seems a bit foolish so I am sure it's something I am not doing correctly. Thank you and any information would be very useful- Rich
