RNAV Arrival

I've been trying several arrivals at un-towered airports in Australia, using mainly RNAV approaches, and I've been having trouble, like many others, with the aircraft missing the IF completely. Majestic have indicated that they are looking at this and may do something in a future patch. Yesterday I flew YSST to YPMQ and I thought I'd enter the RNAV fixes and see how the aircraft handled things. The FMC didn't want to enter my fixes which I was reading straight off the Air Services Australia approach sheet for YPMQ rwy 21! To check what was in the FMC I loaded the FMC approach and quickly noticed the nav data (cycle 1403) was showing different fix names, although in the same positions as the chart! From memory the chart uses fixes which begin with PMQ but the nav data   fixes (cycle 1403) all begin with PQQ. Maybe it's just old data and they work ok but be warned just in case you need to enter a fix in a hurry.
