The radio was the same for the 04-05 year.
IN 06 and up they used a different radio that had an input, but it was bigger. So it will not fit in your dash, without updating your center console completly, wich would be pointless as it would cost more than aftermarket. Here is an idea though, the six disk, wich I assume you have, holds six disks of MP'3, just burn your files onto disk, and play them through your factory radio..............and there you have it, way to many hours of music, over 60, and no need to swap radio's out..............
I am sure there must be an aftermarket adapter out there that allows you to go through FM modulator though............
