radio-cassette swap to radio/cd player?

Need to take out 1998 Blaupunkt cassette player--from Clio 11
To fit Goodmans radio/cd player
there are 3 ISO plugs in Blaupunkt
There are 2 ISO plugs in Goodmans
Aerial sockets are different---ones like an earpiece--the other is a tube--with coaxial connector at end
