Upgrade XC60 seats

[IMAY2023]

Would you happen to have the part numbers of the seats that have heating, ventilating, and massaging?

There is no such "whole seat" part number.  Each part (heating element, heating module, vents, pump and massage air pillows) is individual.  
You need to find a whole used seat and replace yours then change the config via Orbit according to the new features.  Search on Ebay or junk yards 

You can also purchase each part separately and install them on your seat but it's not always possible because the frame is different. 

As far as I know,  s/v60 and s/v90 front seats are interchangeable.  Back seats V60 <> V90 and S60 <> S90.
XC series I do not know but most likely front seats would be interchangeable  too.
