Is there an FS2002 compatible INS available?

I was told that Probst's new 727 panel had one, but I can find it (the INS). Can you??It would be so great with an INS to fly the 727, DC-9, DC-10 etc. It's a bit hard to fly VOR/NDB to VOR/NDB on longer flights, specially trans-atlantic. I don't like to use the FS2k2 GPS. Sometimes I use the ACS-GPS with the DC-9 though.Cheers,Christian
