Well you could use a rf modulator like this or this some people say that they dont sound good, I have used them and they sound as good as what your fm stations sound now. This would probably be your best bet for now. Ummmm..... OK where is my tuner he he he

Actualy I really could use a tuner I am putting my empeg into my 84' jaguar xjs and I would like that option. Oh and yes it still has the v12 in it.
