2006 is250 with ML unit aux port won't change. stays in CD mode.

I addressed the issue by:
Changing the wires. Using a 3.5mm jack every time.
Checked the fuses only one burnt is my cigarette lighter.
Did the Fm turn off car turn on car turn on audio still on FM and switch to aux.
Tired it with something plugged in a playing, and something plugged in and charging.
Is there a metal finger inside that is out of reach?
or is something fried? and how would I know its fried?

I did these all unplugged and plugged.

the AUX plug was never working and bought the car used. only has 38000 on it.

anyway of fixing it?

and is there anyway of downloading music ontop the unit?
