I gave up on using Wayfinder a couple of years ago and uninstalled it. In all of that time I haven't had a need to reinstall it. (I do believe I did find it listed as "map" in the installable applications.)

Currently, I am using Navit. It scores over both Wayfinder and Maemo-Mapper in a couple of important ways:

1. Using OSM Maps, I am able to get map updates, including fixes and additions I enter (using OSM2GO).

2. I can do routing right on the device without an internet connection.

3. It doesn't crash like my install of Mameo-mapper does.
