The little black one is for a Wired Remote, WR is clearly printed on it, and the website confirms it. The 3800 does NOT have the extra jack that the 4800 doesdesiscrubs said:so, from what i read on the internet, it is an aux input, just like in my 4800...so, you can get a long 3.5mm cable, and run it from the back of the receiver into your armrest, glove box, or wherever you choose, then switch the Aux on through the receiver, and when you press the big silver button to scroll through sources (Tuner, CD), AUX will come up and you can listen to your MP3 player through the receiver...pretty nice ay? well, gluck and if you have more questions, lmk
You can get a few adapters for it, personally I use the ipod one, but as an aux i have one that turns the blue IP bus into a set of rca's (the CD-RB10) http://www.pioneerelectronics.com/pna/v3/pg/support/details/0,,2076_310070343_35681,00.htmlchadi said:if you could pm that would be cool....so for the blue one, i would have to go buy the adapter peice, and is it only for ipod?
