I am looking for a technical manual for my car stereo. I own a 2003
Toyota Matrix with a factory installed in-dash 6-CD changer with AM/FM
radio. The front of it has the model number "AD1801". I intend to try
to hook up an iPod adapter device to the AUX input (which is a 2x6 pin
input).

Most people who have tried this with the 6-CD changer have not had any
luck getting it to work. (Like here:
http://www.audiobanter.com/q-t_26453-AUX-POD-and-Toyota-Matrix.html) I
have been told by people who make the Neo iON that it may be a matter
of doing something like holding down the "seek" button to get the
stereo to recognize the AUX adapter. I also need to identify the
always-on 12V power line so I can charge the iPod. If I can't get that
information, I will buy a line tester.

The specific information I am looking for is:
1) Which line I need to tap to get always-on 12V power going into the stereo. 
2) What button combinations will work to get the stereo to recognize
the device on the AUX input port?

An acceptable answer would be a pdf of this manual or a valid link to
where I can buy it if those specific questions can't be answered.

Clarification of Question by uberfluffy-ga on 16 Mar 2005 13:52 PST

Oh, I forgot to add that I contacted Toyota directly to ask for this
information. They had an odd response considering that I have taken
the radio out of my dash and found the AUX port already:

We are sorry; we do not have any information on auxiliary ports for
your audio unit. Our Original Equipment Manufacturers(OEM) audio units
do not offer auxiliary ports.

.... After two months of trying to resolve this with
PAC, they just informed me that the AUX-POD will not work on this
stereo. Apparently, although this stereo has an aux port on the back
and an aux button on the front, it has no aux capabilities. HOW STUPID
IS THAT! DECEPTIVE TOO!

corvallis-ga: Yes, I've seen that, too. I'm not convinced that PAC is
a definite source, so I'm still looking for a manual for the stereo.

this MAY be an information source.

This is a web site for people doing iPod hacks.

This small piece has some interesting links; does this help?

corvallis-ga: Thanks for all those links. Your comment on
installdr.com will probably answer my first question, and your other
comments give me some good background information I hadn't seen yet.
Since it could be that there is no answer to question 2, why don't you
re-post what you wrote in an answer to my question so I can give you
credit for it?

Thank you for the compliment that I may have come close to "answering"
your question(s). It appears I cannot post an Answer as I am not a
Registered Researcher, and Google Answers is not accepting new
applicants at this time. This is ok as I've run into this before. I
will post two more links here, then get off of this interesting
challenge.

Oh, that mobile information labs web site looks like it might have
what I'm looking for... or it might be a scam. I will have to think
about if it's worth $13 to find out. It seems reasonable that they
would charge for the diagrams, though.

Anyway, thank you for looking up all this information. I'm sorry that
you are not an official google researcher. If there are any Google
people reading this comment, I would like to recommend corvallis-ga as
a google researcher.
