Nice looking car
But its now how old it looks, its how old it is.
I highly doubt that phatbox is supporting Toyota stock stereos that are 12 years old.
I think you have 2 options for getting a phatbox in your toyota.
1) Kenwood FM Modulator (I was going to use this in my 2006 Mazda 3 before I got the phatbox working with the stock stereo)
2) Kenwood Head Unit (This is what I did in my Saturn VUE)
