If you are just looking for the free version of Wayfinder:
My advice is to uninstall the Map program and reinstall the latest version first. Downloading large maps via the tablet can be problematic.
Then visit http://www.navicoretech.com/Consumer...B/wfnavigator/
on your PC and move the files over to your internal card.

This is what I did, less headaches, no tar files.
