Aux input on 00+ with Bose, Onstar & no cd changer .

[Oldsman105]

I have been searching on the forums for info on Auxilary input on the Stock headunit for our cars . There doesn't seem to be a straight forward solution. (or I haven't looked in the right place)


Or should I look for a new headunit (would perfer not to)

[RJGill84]

I've been searching for a similar solution. I would like to run a cable into my center cubby hole for my iPod/iPhone.

Getting rid of the stock radio causes a whole host of other issues. Without a lot of extras, you'll lose your door chimes, OnStar (which doesnt really matter in your 01'), etc. That's why I'm looking for a solution that retains the stock radio.

Do you have XM oldsman?

[RJGill84]

I don't believe XM was a factory option on 01' models.

[Oldsman105]

Do you have XM oldsman?

Nope


No wiring in the back corner either.

[lewis26]

Hmm, well that makes it even tougher, Hopefully ddalder will chime in soon. He might know of something.

I have a solution, but it only works with cars with factory xm.

[ddalder]

In theory it shouldn't be impossible. In order to achieve this you would need to swap your head unit to one with a "BAND" button instead of "AM/FM". Then there's just the matter of adding the wiring for the Digital Radio Receiver. If you have a 12 Disc Changer this would be an easier project since the input on the back of the radio is shared between the CDX and XM module.

I built a custom harness for another member to add both the factory CDX and DRR to a 2000 MY vehicle. I have no reason to believe they won't work but I'm waiting for them to be installed as confirmation.

The problem with using the remote audio input on the OEM radio is that the head unit needs to sense an appropriate class 2 device is installed in the vehicle before it will select the input for use. The modules that lewis26 is talking about "looks" like one of these devices to the head unit, only the input source is what you have connected, not what the radio necessarily believes it is. Typically, if you use one of these devices you can't add the factory XM because this is the system most of these modules will "emulate".

[Oldsman105]

Unfortunetly I do not have the 12 CD changer.


So there is no mass produced Aux input for my radio (non band button). Switching to one with a band button would not be the soultion of choice for me. I was hoping to find a plug and play soultion.

[RJGill84]

If it's a stock look you're after, the 02+ (I believe, possibly 03+) are the radios with the band button. Other than that, they look identical to ours. You should be able to get one for very cheap, and then just sell your old one.

[lewis26]

Darcy, I am not using one of those modules, and know that they don't work.

What I did was tap into the common audio signals coming out of the xm box with a headphone extension, allowing me to listen to xm and my ipod from the same source. I simply just go to xm channel 0, where there is no audio, and play my ipod. The radio still sees all the data information from the xm module, I simply replaced the audio data being outputted.

Oldsman, there isn't a mass produced option for your radio, I think simply because of gm's data bus system usage, and the dock and lock connector. This frustrated me for months, until I figured out my current solution with the help of another member, hawkjet.

I PM'd him a link to this thread, and we'll see what he knows.

Use an FM modulator that is WIRED. Wireless ones suck. theres one best buy sells. Its by scosche. goes in line with your antenna on the back of the radio. It gives you a 1/8 input and an off on switch. Sound quality is like ideal FM reception.

The 2K+ Bonneville is entirely different than your vintage of Bonneville. There is no easy way to connect it behind the radio (if using an OEM head unit). There are other possible options. There is a connection at the base of the passenger side 'A' pillar that uses a standard male & female coax connector. This is the same size connector typically used in many aftermarket radios though, not the smaller one used in many OEM applications. You'll need to remove the dash pad to access this if you decide to go this route.

I have seen modules that allow you to replace the XM radio module with an iPod input (albeit quite some time ago). Regardless, your option works too however, the problem is that he already mentioned he has no CDX and no XM radio so to add all the wiring is more work than he's interested in doing (although I still think it's easier than installing aftermarket). He would need to add either the CDX or XM radio module so the radio would sense it on the Class 2 data bus and select the remote audio input. As I mentioned, there is no way to have the radio select that audio input without seeing one of these; this is simply a part of the software in the head unit. If he adds either one, it would then be easy to wire the iPod interface to the audio signal instead of the XM or CDX source.

It would be better to add the CDX from the standpoint that he wouldn't need to replace the existing head unit to make it work. His current one won't support what you're suggesting but will support the CDX. The priciple is the same in both cases.

[lewis26]

Sounds good darcy, I was just clarifying what I have done so he doesn't think I have a module or something that I don't.

I know hawkjet added something directly in under the dash to the wiring harness, to allow him to do something similiar. I don't exacly remember what he did, and he hasnt been on here since early June.

Is there a way to fool the radio into thinking that there is really something on the data bus even though there isn't? Is it a 2 way communication, or just a voltage or something?

Sorry, no problem. I may have misunderstood what you were saying.

I recall back when hawkjet was working on this and I don't know exactly what the final version ended up being. I had sent him some terminals a long time back so he could wire into the factory connector under the dash pad where the remote audio connections are made. I do recall he had experimented with a few different modules at one time. I'm just not sure if this was truly the 'end' result.

Unfortunately there is no way to fool the head unit. When power is applied to any of the Class 2 modules (CDX and XM receiver included), they register themselves on the data bus as an active module. This also ties in to how some DTC's are set (when a module fails and stops broadcasting a regular State of Health message another senses this and will set a DTC). It's important to have all this intact. If the radio doesn't sense this, it won't let you select the device. This means that as you cycle through your choices (XM1, XM2, CDX, etc.) you will only see those that are actually available. It's partly because of the regular State of Health (SOH) messages that every module broadcasts that it becomes difficulty to fake the presence of one.

[lewis26]

Okay, thanks for clarifying Darcy. You seem to understand our car's electrical/stereo system better than most people here.

Hmm, so at this point, the easiest option for the OP would be the wired FM transmitter, or to put in a CDX and wire in an aux cable to that, unless I'm mistaken.

Hello everyone,
I haven't been on this forum for some time. Hello Darcy - long time no talk! You were the major resource for me to get my system working. THANKS again!

lewis26 PMed me about this thread and I noticed some incorrect assumptions/information. I'll clarify this now:

In order to achieve this you would need to swap your head unit to one with a "BAND" button instead of "AM/FM".

Sorry Darcy, this is not accurate. I don't have a band button and I just drove from Seattle to California while listening to my iPod.

The main difference between the head units is mostly the nomenclature on the button. There is a difference in the radio's firmware because of the satelite radio option, but it seems to be in the radio and not something the Class 2 Serial Bus knows about.

Darcy, I am not using one of those modules, and know that they don't work.

Well, they do work... sorta.... In your case Mike, you wanted both iPod and satellite radio. The module won't do both - but it will do either one. So with the module, if you wanted to use your iPod, you would loose the satellite. This is why I suspect that Class 2 Serial Bus doesn't know the difference - just the radio.

Getting rid of the stock radio causes a whole host of other issues. Without a lot of extras, you'll lose your door chimes, OnStar (which doesnt really matter in your 01'), etc.

I have an '01 Bonneville and my OnStar works just fine. GM has an upgrade for them.

It looks like you don't need the harness they provide and you'll have to add your own. That is what I did, it wasn't difficult.

here is a wired fm modulator

[lewis26]

I knew Hawkjet would have the solution!

Read the post he linked to. It explains everything.

There's the way to do it oldsman, just takes a little bit and work and money, but will offer you a direct input, along with better quality than an fm transmitter.

Sweet!

This is what I was looking for. Its a little more involved then I wanted, but its worth it. Does it also have a extra input for my satelitte radio or do I need to go a diffrent route?
