Hi, Neal
It is with your provided files that I could successfully back it up before patching.
I then moved to the second stage:

"Now put your unit in preboot mode. The easy way to do that is to hold the battery symbol on the main screen ['Where to?/'View Map' screen] for ~ 6 seconds until a hidden menu appears." ==> I did it with success.

"Plug a suitable usb cable into a REAR port of your PC and then connect the nuvi. When you see the unit's details appear in the window to the right of 'USB Device', click 'OK' " ==> it flashed less than a second, and I missed the right moment several times. Finally, I was able to click "OK" when it showed on "USB Device." However, it showed an error message as loaded:

App: Updater
At: 12/27/2015 6:39:21 AM (UTC)
OS: WIN32 Windows Platform, Major Version: 6, Minor Version: 2
Processor: Pentium Pro or Pentium II, RAM: 4194303 KB
IOU_USBLINK.CPP-710-2.7

Nothing is easy for me....
I nearly got there, but one more step with your assistance is needed.

Thanks and peace.
