I recently bought a Lowrance iFinder and am trying to get gpsbabel to read
the .usr files it outputs to its mmc card. I've obtained the "specs" (if you
can call them that) from Lowrance, but I'm a bit lost as to where to go next.
If someone could take a look at the attached cpp file (which is what Lowrance
sent me for unserializing their data) and the attached .usr file (it has a
couple of waypoints such as 001 and Und) and tell me if it is even possible
to decrypt the data given this information it would be appreciated. At this
point I'm only interested in extracting the waypoints, not the routes or
