Hi,
it's better to check an X-Functions module with a C or CV, not a CX,
because you won't see more X-Memory for obvious reasons...
It's similar to trying to check a QUAD Memory module in a CV: It simply doesn't make sense;-)
At some point in production, HP seemed to have either renumbered the module itself not to carry the package name anymore,
at least I have seen many X-Functions modules which don't have the 82180A printed on their back,
while the whole product (module, manual, box) is still the HP 82180A.

Just like Raymond, I agree that the XFUNCTIONS module is not going to do anything in a HP-41CX (it may even conflict - although I haven't confirmed that). In particular, you're not going to get access to the X-MEMORY part of it, i.e. the 127 registers (I *have* tested that ;-).
All my XFUNCTIONS modules report -EXT FCN 1B. You obviously have a later version.
