i have a 2004 ls with the stock radio. it has a button that says cd/aux on it, but no cable or jack. im going to make some CDs so it isnt a big deal, but i would like to be able to plug my cellphone in and play my music.

is there something i have to connect somewhere or whats the deal? somebody said maybe theres a jack in the back of the radio but i dont want to pull that dashboard out unless i know for sure. why would they put it in the back anyway? :WTF:

There is no Aux input for this generation of Impala. Do you have the cassette deck option?

i dont have a cassette deck but it does have the aux button so i dont understand why they would put the button if there is no aux input. thats odd.

It might be for a trunk-mounted CD changer or something like that.... Maybe there is some sort of input on the back for another piece of equipment - might be a proprietary connection though.

Does anyone know if that is the case? Can a trunk-mounted CD changed be connected to these head-units? It does seem kind of strange to have an Aux button if there is no aux connectivity...

Auxiliary just means additional support so in this case a cd is just additional audio support.. It's an ambiguity. For instance if you had the cassette and cd option the tape deck button would read tape aux.. The cd button obviously says cd aux.

I don't really buy this explanation. They already said "CD" so they don't need to say "AUX" besides that the term is normally used for an exterior audio source.

According to your signature you have an 03 base, Does your car come with a CD AUX button? If you doubt the explanation then tell me where your aux port is. I had an 04 LS I will tell you beyond the shadow of a doubt I had a CD AUX button and no aux port and it was never an option on the car.

I'm not disagreeing that it doesn't have an aux port I'm just disagreeing with the 'need' to say "CD AUX" when "CD" is all that needed to be printed there. It implies that there's an external audio port when there isn't.

Inspired by this thread, I looked in my 02 owner's manual. For the radio with CD, it says "CD AUX". For the radio with cassette player, it says "TAPE AUX". But for my combo CD/cassette, it says "TAPE CD".

FWIW, attached is a doc I culled from the web that describes how to add an aux input to a factory radio. HTH.

I realize this is an old thread but for future searchers I'll throw this in. There IS an auxiliary jack on the back of most of the 2000 - 2005 radios, the RDS radios for certain. It is the smaller plug to the passenger side of the main harness connector. My loaded 2001 base model had the CD/Cassette/AM-FM RDS head unit and a harness plugged into the output that ran to the trunk and was folded up and taped over on the passenger side behind the liner. This was for a remote CD changer, it wasn't a "factory" installed option that I have ever seen but it WAS a dealer installed option. It was originally my understanding that after 2002 or so the harness to the trunk was omitted as very few people opted for the remote changer in Impalas however the AM-FM/CD non-RDS radio in my '03 has the connector as well as the harness. So....? :dontknow:

The wiring schematics for remote input devices are shown on pages 8-444 and 8-445 of the Helms service manual and the Remote CD changer is referenced on 8-495 and 8-496. At the bottom of 8-481 it states that the remote CD changer was a dealer installed option and to refer to the changer manufacturers instructions for the replacement procedure. Hope this answers some questions for someone.

Moved the radio from my '01 to my '03 and got it unlocked tonight. When I swapped I also added an Auxiliary Input Adapter that plugs into the previously mentioned remote CD plug in the back of the radio. Tried it with an old Creative Mp3 player and it works great!

Can you share some pictures how its wired, i found a pin out of the small connector and it shows a left right and common for audio input, but do i havent tried it out, i am wondering how would it work?
Do i press the cd/aux button and the radio will detect the sound??

Any ideas if this can be done?

Thanks

Sorry, no pictures. As you're looking at the front of the radio there is a plug in on the lower right hand side on the rear of the radio. It is for the dealer installed remote CD changer that it seems no one ever had installed. I bought a commercial adapter that just plugs into that, it was about $70 on Ebay and it works great. Yes, you hit the CD/Aux button twice to access whatever you have plugged into the adapter. Actually makes the OEM system sound pretty decent.

It sounds pretty awsome!!
I found the pinout of my 12 pin connector, and i wired a cable to it, but i have the band / caset aux button and it doesn't access the sound i have playing on the connector.
I think its a gm thing.

We have a 2000 Chevy Suburban. We have a "CD Aux" button and the Aux goes to the cassette tape player and the CD goes to the CD player. I'm looking on this thread because we're buying another Suburban with a "CD Aux" button but there's only a CD button and I'm wondering if there's an Aux port hidden somewhere or if we can attach an Aux cable to the back of the radio.

On Ebay what specific product name can I look up to find that commercial adaptor? Thx.
