Whats the best way to swap files from one Nuvi 660 to another?

 

I have 2 Garmin Nuvi 660's one has updated maps and the other doesn't. One also has the main splash screen with the name of the company that owned it previous to me. It does not have the splash screen files to ad or change it. So I want to delete and transfer one to another. What do I have to do?

Connect To Your PC

You can connect the 660 (both at the same time if you have 2 USB ports and 2 cables) and use Windows Explorer to drag-and-drop files from one to the other. All except for the map files. The map files are locked by the license key to the unit they are installed on. You can physically copy or move the map file, but they won't work when you turn on the GPS.

What files are the locked

What files are the locked map files so I don't waste time moving them around. Garmin as you probably know has a extremely slow usb speed.
