I have a Nuvi 765t and have the latest CNNANT2011.31 maps installed on a patched version of MapSource 6163 on my PC.

I am using the selection tool to copy and transfer all of map onto my 765.

This method will NOT update anything except the map img.

I have the newest copies of the JCV, 3d files from when I did a lifetime update on my 775 and saved the install files.

So.... do I just copy over any of the "new" JCV, 3d, basemap, TZ files to the 765 now ?

And do I need to delete the older files off of the 765 once I copy over the newer JVC and 3d files etc ?
