I can't create new datum in Autocad Map 3d

[emre3522]

Hi everyone,
I am a new member to your group. I have a question. AutoCAD Map 3D 2012 program, I find it difficult to add new Datum. I want to add datum ITRF96. ITRF96 datum does not exist within AutoCAD Map 3D. "Create a new datum" I tried to create a datum with interface. I wrote down the parameters of datum.
datum code: 6654 (It is ITRF96 code, It is not defined in AutoCAD map)
Description: The International Terrestrial Reference Frame 1996
Code Ellipsoid: GRS-1980 (code: 7019)
Source: International Earth Rotation Service (iers) Technical Note no. 24. Also IGN Paris http://lareg.ensg.ign.fr/ITRF

but the "datum code" says that part of the error. What can I do?
Waiting for your help. good luck to everyone.

There is information you share, respect for labor are odd!

The following _ADEDEFCRDSYS setup works for me in Map2006, so I hope for your 2012 as well.
You should not type in an EPSG numeric code, but an alphanumeric one, as ITRF96.
