Tricking the head unit into thinking the mp3car is a cd changer
*if there is already a discussion on this, someone just link me to it but i didnt see one*
Ive got a good deck right now, and want to use it. it doesnt have auxiliary in, only 2 RCA in's and a bus controller for a cd changer. I want to trick my deck into thinking the mp3car is actually a cd changer, so that it allows me to play music as the cd changer. my deck is a sony. does anyone know how to go about this? is it as simple as shorting 2 wires, or more complicated with signals? (i understand that there must be 'nextrack' and 'nextdisc' signals and such, but in our example we dont need that, we just need to have a signal pretending like cdchanger, and yelling "hey im here")
ok too much typing, and too much typing discourages people from reading, so give me ideas/thoughts/instructions.
