To give some more info about this...

Q: there is no need to replace the cristal...
A: Only the chip needs to be removed, as for the rest you could leave as it is.

Some notes,
In order to use these VuJ chip you need the module version and thus also need to mount a connector for it.
Keep the wires long so that you are be able to connect the VuJ board on the parts side.
Also, solder the wires as given on the drawing, use at least the four wires 3.3v/Gnd/Sda/Scl, the Rx/Tx are basically not needed because this box will work without them.
The ground and 3.3v can also been taken from the parts side, only the Sda/Scl wires needs to be soldered on the print side.

One note...
Do not drill any hole trough the board to bring the sda/scl wires to the surface, you could end up with a death box due the multiplayer's board.
