Correction: I enter data manually from Shift-Z in FSX. Anyway I did what you suggested, the problem is still there. After the first attempt I turned off the ADIRU, waited 30 seconds and turned it back on. The CDU prompted for coords after a few seconds which I entered from the scratchpad copy. I watched the countdown from the ND screen and then, another prompt "SET INERTIAL POS" came back up.

If I go to page 2 of the POS Init screen, the airplane seems to know where it is.
