|It will not make a CV into a CX|

You're only getting half the story:
You'll get time functions but you will not have a full CX, only a CV with "Time" and "CX Time" functions. To have a CX you need the extended memory functions which are in the rom contained within the lcd module. Parts not included.
And now the really big omission: The module will only fit in a halfnut version unit.

The service manual is not particualarly clear about this, but I believe the extended functions ROM and the extended memory RAM are in this module (along with the timer chip, crystal, time functions ROM, etc).
_HOWEVER_ the 41CV main ROM (which is in the LCD driver hybrid) will not look for the extended functions ROM. If yo add this module to a halfnut CV, then you get the time functions, but not the extended functions (I have actually done this to see what would happen).
