Is this even possible (money is not an issue)?

Is it possible to set your car up where it can play 8 tracks, cassettes, CDs, Records, and an iPod/iPhone? How much if it is possible?

I'm sorry if I sound stupid. I'm just wondering if it's possible. Please no rude comments… XD

Sure, anything is possible, esp if money is no issue…

Of course it's possible.

You'll find that with enough money nearly anything is possible.

You can use any car stereo and add a cd changer, you can add this interface,

to the interface you can add 2 sources aux for the 8 track and to the axu2 you can remove the cable and add an ipod cable or a bluetooth interface,
'
now you have
radio
CD
8 track
ipod
aux

all from the same audio source the link is for a gm adapter but they exist for almost any car stereo from 1998 and up
