As long you are using iGO 8.3.5, you should put in map folder only the files -> fbl, fpa and ftr.
The others (fda, fjw, fsp and hnr) will not be recognized by iGO 8.3.5. They are specific only for iGO Primo (or Becker).
On the other hand, the message with "outdated maps" is due to license issue, so you will need some "fresh" license.
