Ok, plain and simple, is there any possible way to add an Audio input on the OEM Infinity stereo unit in my 04 Endeavor XLS with the 6CD changer bult in? I see there is nothing plug and play so I assumed that someone has cut and spliced to make it work.Please tell me I can take a 2.5mm Headphone output and splice it in the theHead or AMP harness somewhere to make this work?

 

I Think Not!!!!

 

Not... really...

 

definetly not

EDIT: The only option that jumps to my mind is if you're trying to connect an iPod. In that case, an iSimple might work. It's a bit of a pain to install, but basically what it does is duplicates the signal of the cd changer and essentially tricks the head unit into running your iPod. Down side is, the cd changer is no longer functional.
