Hey everyone

I have a 2004 350Z Enthusiast with the OEM 6CD changer Bose head unit and i am trying to add an AUX input to the system without changing to an aftermarket or breaking into the unit and tap into the wiring.
I had a few questions about the Stock unit.
is the 12 pin CD changer port available on the back of the Bose headunit even though it has a cd changer built internally? reason asked is that there is this item and it shows the wiring within the page >>

second question. in the trunk by the jack and tool kit there is a plug. when i first bought the car i thought they took something out and left it there so i checked online and it seems to be a plug attachment to the Audio system.
is it for Sat radio? or does it tap into the audio harness for additional equipment? I personally couldn't find anything online that plugs in the back.

Please let me know if you guys have alternatives to this problem (aux input with stock Bose 6cd head unit).

also there is this plug n play antenna add-on

will this work?

Thank you so much in advance for reading my thread

 

I have no idea why people bother keeping that junk radio. Even a $30 aftermarket CD player will sound and perform way better than the OE trash.
