Aux Port - Canadian 2006 Yaris

[sergo]

Hi guys
Very interesting thread. I have fujitsu 08600-00997 cd stereo, with D74 aux connector at the back, and there is a jack plugged in with all the wires connected to the pins used by aux input (17,15,16,19) according to the manual.
The problem is that I can't trace the cable, and there is no aux jack next to emergency brake (I popped plastic covers and there is nothing there).
Does anybody know if this model actually supports aux input (no buttons on front panel)
