Could not input addresses after downloading latest map updates from Garmin (long)

 

After downloading and installing the latest map updates from Garmin on my Nuvi 3790, I launched Garmin BaseCamp just to play around with it a bit and learn how it works.

About 10 days later, today, my wife took the Nuvi unit to enter the motels we will be staying in on our next trip; hotels in Indiana, Iowa, and Nebraska but was unable to do so. The unit would only allow her to input addresses in Maryland, Virginia and the District of Columbia. After checking the various settings, she went to Tools > Settings > My Maps and found the boxes checked for only the following maps:

CN North America NT
2013.10.3D

CN North America NT 2012.30
Baltimore, Maryland, Arlington, Virginia, Washingt

The boxes for these maps were not checked:

Cnn – Na – Dem
North America DEM

CN North America NT
2013.10 ALL
trafficTrends North America 4.26

Once she checked them, all was fine and she could input those Indiana, Iowa, and Nebraska addresses.

What happened here? Is this normal? Seems to me after previous updates of my Garmin maps, everything ran just fine.

And another question where did these maps come from?

CN North America NT 2012.30
Baltimore, Maryland, Arlington, Virginia, Washingt

I don’t ever recall seeing them there before.

I keep a log of what I do when I download updates, etc., from Garmin and here are my last few download in case this gives anyone some insight into what happened with this most recent download.

24MAY12.
Checked for map updates in the menu bar; reported ;
Version 2013.10
Proceeded and got a window and progress bar.
First time; nothing happened.
Quit Garmin Lifetime Map Updater; relaunched, and this time, about 30' after getting , a small window appeared telling me to attach my Nuvi.
Did so and this took me back to the window and its progress bar and the maps were downloaded to the GPS unit.
About an hour later, got a small alert window with .

02JUN2012, launched Base Camp and was notified that
there was a firmware update. Downloaded same.
From Tools > Settings > System > About

Also in early June 2012 downloaded new maps

In my Home/Library/Application Support/ Garmin/Maps/, I see

When I check on my NUVI 3790 > Tools > Settings > myMaps:
the resulting window shows the following map boxes checked:

Cnn – Na – Dem

CN North America NT

CN North America NT 2012.30
Baltimore, Maryland, Arlington, Virginia, Washingt

Many thanks.
