330 and 332 should be compatible.
Not sure exactly what the difference was (I know the diff between the 332 and 337 was the single/dual freq FF.)
The later models (i.e. LMS-520C/525C) will also be compatible, but you will need an adaptor to plug the blue network cables into the red network plugs. Later models also came with the LGC-3000 GPS antenna, which was updated and hardened (I think.)
