hi guys , would anyone be able to tell me if the factory cd player out of a late au will swap straight over with the cassette player in the early au"s, is it very hard to do? are special tools required to remove the old cassette player? , cheers in advance

yes it will swap over
as in remove and replace no need to cut anything
make sure u have the radio code for the new player

and i dont think the steering wheel controls will work
