I have a '89 Toyota Cressida, but I have NO idea how to install a cd player in it, since there are like two parts to the whole radio.

help please?!

also, can toyota cressidas use sirius satalite radios?
will i need any special parts?

i should probably mention that my tape player doesnt work... when i press the tape button nothing happens, as well as the eject button

take it to a shop
