Adding AUX-IN to old boombox ??? IC question...
 

I have an old boombox that I want to hook a old android phone into for Pandora via mini-phono plug. I found an AN7312 IC on the board. I'm assuming that I can just hook my right-in to pin #7 and left-in to pin #8 and hook the phono plug GND to pin #1. Can someone verify this for me?

Suggestions on better methods? I also found a 5V+ on a board so I'm going to run that to a mini-usb to charge the phone.

Well, I hooked it up the way I described and I only get audio if I push play on the cassette player. Horrible audio unless I turn the android down to the lowest level. Will work for now but was hoping for better results...
