This is made for a Stereo with a CD player WITHOUT an AUX option.
Caution. I take no responsibility if this messes up your Cd player, your MP3 player or worse. This mod is not perfect but it works for my purposes. To you nay sayers keep it to yourself.
This mod requires you to take apart and reassemble your cars cd player if you don't feel comfortable doing it then don't
The items I used in the mod are:
Pioneer DEH-3400 (Make Year 2002)
30 Gig IPOD video
Old pair of headphones
Step 1: Stereo Removal
Step 2: Disassemble
Step 3: Find the "input"
If you look closely you can see to the right of where the ribbon is attached it says on the board "ROUT" , "LOUT" and "AGND" These are the three connections that we need to make.
I can't say if it is like this for every cd player but it works for mine. This idea here is we are tricking the CD player into thinking that is it playing a CD.
