Hey Guys,

I know I had a thread a while back asking for instructions for installing an AUX on a 2003 Bonne, but I finally figured it out, and figured I would share the info.

I saw mods that had other features, cars with XM could mod for AUX, cars with tape players could mod for AUX, but nothing that would work for my non-XM non-tape having car.

After looking through a bunch of forums, finally found some info on a Grand Am forums(can't find the link right now).

Any AUX cable should have three wires once you strip it, Left, Right and Ground. This picture shows how to ground it.

This view is from the top of the radio(with the cover off, obviously. The pins you're soldering to are parallel to the faceplate, to the right of the CD mechanism, when looking from the back:



You might want to take the CD mech out to get a better angle at it.

After that, you just run the cord through the side of the radio, and wherever you want in the car.

You need to have a CD in there, because you're "tricking" the radio into thinking the AUX audio is from a CD. I just burned a Cd with a 5 minute long MP3 file of no sound. I burned it in iTunes, and put "none" for the amount of time between tracks, so it doesn't interrupt. Works great.

Hopefully this helps anyone else in my situation, if you have questions, let me know.

EDIT: FYI, seems like this is the case on all Pontiac radios in this era(2000-2005ish). Obviously do this at your own risk, but seems simple.

Nice work! Just one caveat: When your CD player laser 'burns out' or for any reason can't read the disc it will stop working.

Nice write-up OP!

Haha yea that's a downside, luckily I work at a car audio shop, so i could probably get it fixed if it does happen.

That's cool but what happens when you want to play a CD?

CD Works just as normal. I haven't tried it, but I think if I play a CD and connect my iphone at the same time, it would give both audios. Or end existence as we know it, I'm not quite sure lol. I'll try it tomorrow.

EDIT: Tried it out, it does still play the CD, but it quiets the CD's volume down quite a bit, and plays my iPhone's audio at the normal volume. I unplugged the phone, and the CD plays at regular volume, so that's cool.
