Hi,
If you aligned the FMGCs & IRS on stand using GPS, and then compared the received VOR Radial & DME distance with the "PROG" page calculation to the same VOR, it would show the MAP shift error to the VOR before you start. If possible I would suggest you did this to two VORs at 90 degs relative to each other from your stand / taxi position.
