The Navigo runs Windows Mobile 5.

Installing XCSoar

  1. If you haven't already done so, create the XCSoar directory in the root of your SD card and copy the files XCSoar.exe, GRecordDll.dll, vali-xcs.exe and possibly XCSoar-PC.exe into it.
  2. Rename XCSoar.exe to MobileNavigator.exe
  3. Rename the XCSoar directory to MobileNavigator

Installing XCSoar on an SD card with shell.ini should also work, but is untried.
