How to revert GPS to previous installed map version

 

Hi All,

I have the Nuvi 265wt with City Navigator 2010.10 installed. I have made a backup off all the files, folders, subfolders on this GPS onto my local PC hard drive. I'm about to update the GPS's map to version 2010.20.

I'm wondering in the case I need to do a revert or back out from the new map version back to the previous installed map version, is there an easy way to do this like copy some files which I have made backup earlier back into the GPS? If yes, can you tell me which files ?

Thank you.
