Really you don't need to keep an outdated CN as the only option if that's what you mean, in that you're saying you have to use the CX Chicago 2014.10 with the CN NA 2014.10? Try using the full CX 2014.10 with the CN 2014.20 with only the one you're using selected. If you do happen to get the conflict problem reported by coastline2001 regardless of selection choice then simply use the solution he proposed in Post #29 and have the full CX Chicago 2014.10 and the CN NA 2014.20 on separate cards and switch depending on where you are, in Chicago or elsewhere. Otherwise match the versions as you said, both 2014.10, in which case you can use just the small MMR only Chicago CX.
Thanks for taking the time to address my query and please do excuse the delayed reply.
YES, I was operating under the notion I had to be running the same CN as CX. However, I experimented around (that means throwing water on a grease fire around here!!) and I have all those cities, but in particular, Chicago. While I'm pretty certain I'll never get to the bulk of those cities and most certainly shall not be walking all the distances I once did, it's a lot more data to have at your side.
Too, as an aside, there had been an earlier remark about the battery life to units like this Nuvi 1300 and the viability as a hand held GPS device just walking about and the reality there is a time issue. There is....but here is a trick I'm learned that's working just fine: It's a battery back up/charger for the device. The charger runs off of 4 AA batteries. I can't report how long the back up supply lasted as it never went out on me! Here is one version of one:

I will say that having that back up device in my backpack with plenty of AA batteries helped me to walk more safely. (Yes, I know it's almost impossible to get lost in Amsterdam as all trams end up back at CS......but I was in ummmmm......some other types of neighborhood.)
