I looked into this, 05 and 06 do have a port in the rear of the radio. If u take the center console apart there is a port in that u plug into and from there u can run the wire to your arm rest and install a 3.5mm port. I think it's 3.5mm, it's early!! Anyway, yes, trip tunes is one form of the device, or a alarm/sound shop will have something similar.
