Well, I think you are going to have a problem getting the radio to accept the signal because it needs some data communication also to let it know something is there. Not sure how to emulate that communication from your Ipod.

Normally PIE makes convertors like this, to either allow an Aux-In, or add a aftermarket CD changer. After waiting around for a year, PIE still says that they haven't come up with a 2000-2004 option, so I went looking.

I found another company that has both a AUX in for the 00 to 04, and a MP3 CD Changer. The MP3 Changer seems to leave a little to desired. Any reviews I found said it was SLOW, very limited to the way the CD'* have to burned, and tough to select songs. The reviews did say that the audio quality was good on the changer.

I have not purchased the Aux-IN unit yet, but if the audio qualiy is good on the MP3 changer, it stands to reason this would be pretty good on the Aux-IN. Read about it, as it says that it will work with your existing deck. (Click on the picture in the center of the screen for more info)

I plan on getting one later this spring for my Tungten T3 to play MP3'* through the stereo. Hopefully it will fit your needs as well.

That appears to be the gismo that we're looking for. That works with Bonnevilles too?

According to the website, they have a specific model that works with the new GM interface protocol. (it would have to in order to 'trick' your head into thinking there was a CD changer attached.)

I've seen some FM modulator deals that work really well, and sound exceptional. However, there are more bad ones on the market than good. I'd go searching for some reviews, and expect to pay, like someone said before, 40 bucks.

Just for everyone'* information, I've worked on projects trying to adapt external changers, etc. to the aux input/control on car stereos. The problem is that you need a MCU or CPU to work the serial communications on the head unit, and the code sequences are tough to get a hold of.

So, if anyone wants to go that route, you'll have to buy a unit that will do all that processing for you. Too bad you can't just stick a jumper in and go from there

The one I posted supposedly does exactly that. I'm not a fan of the FM modulators, because of the limited frequency range, and the additional two signal conversions (line to FM and FM to audio) vs. using one of the AUX interface units. Mine should be here Monday, and hopefully installed before next friday. I'll post how well it works.

We need to find one of these compatible with the 96-99 CD units, which are designed to accept the slave cassette decks.

Maybe when I get a BMW...

I have tried an FM modulater from Radio Shack. Lousy sound, lots of interference.
There are good ones?

My 1998 SSE has a tape deck. I am reluctant to change it as I assume an aftermarket CD player would not use the steering wheel buttons.
I am happy with the Bose sound. Its great.
I assume I would have to get a GM CD player to work with the steering wheel buttons.
