Sids and stars dont match up

can someone tell me please, why the navigraph sids and stars dont match up with the FBW a320NX FMC ?? or does the FBW have its own Nav Database ?

what do you mean with “don’t match up”?

The FBW uses the same files as the sim, so at least the source is the same. But the sim flightmanagement system is buggy and bot really complete (ie you can’t select transitions). The FBW guys make a better job and at least in the latest dev version, the terminal procedures in FBW looks good.

But to be 100% sure what you mean, please can you give us an example with screenshots (sim and FBW).

Thank you
