Well, if it works well, good on you :) you’re the only person I know that has monkeyed with the Denso - I’ve had it in pieces and can’t find a decent audio-in to do the phone mute hack that you can with the AS2

I only pointed that balanced thing out because it’s the cd changer output that is balanced (as our AS2 head units know) - yet saab saw fit to connect a balanced output cd changer to the sig/gnd inputs of the Denso :) Talk about corner cutting....

I was actually only following up a clue from a US owner who appeared to have tried a similar trick, but I can't find the forum it was posted to any more!

GM cutting corners so they can use a cheaper, off the shelf component? Surely not!

Must be a first, surely?

Oh hang on, I have to open my petrol cap flap myself in this model, do I? :)

Did a similar hack on an alfa 166 that also had a chance changed in the boot. But with that it already had left right inputs using rca connectors from the cd player.

So just removed them. Rca to 3.5mm Jack. Then left cd in the multichannel playing. Worked well.

Today arrived my order, a female jack with cutoff function. Soldered all 5 wires and connected the normally closed position to CD SIGNAL LEFT/RIGHT.

It "worked", in a particular way. If male jack it's disconnected it will normally play cd changer input at full volume. When plugging the male jack, both cd changer music (at lower volume) and mobile device's will be heard at the same time. That it's not that bad, since you can hit pause and cd changer music will stop playing and only aux input will play. Worst problem it's that an annoying buzzing can be heard only with key in "on" or "start" position. I think that a ground loop isolator it's needed. Otherwise, with key in off position it sounds good to me, also if you use this kind of female jack

https://www.ebay.co.uk/itm/391210590128

you can use typical saab blank caps (previously emptied from inside with some rotary tool like a dremel) and it will look as good as factory. I will try to take a picture tomorrow with more light

I hope this can help somebody, also if there is a way to make that buzzing disappear without a ground loop isolator, it would be good to know :D

Now it's working, no buzzing or weird noises. Just needed to wire jack ground to one of the L or R CD CHANGER GND. Also, the side that I connected to the ground mutes fine :D
I suppose that if you want to mute completely you can just wire jack ground terminal to both L & R CD CHANGER GND, but that's enough wire cutting for today. Here is how it looks

What's the volume like? Does it need a preamp?

Volume it's significantly lower, but bareable. Just 2-3 vol+ button in your steering wheel and will play almost the same volume as before. Only remember to bring it down again when you iterate to your cd changer if you don't want a jumpscare

My socket was from Maplins but looks pretty much identical.

C_B_V - did you use screened cable (which I have) or just individual wires?

Wired it individually, I used a connector strip but I will probably change them in the future to this kind of connectors for a easy removal if I need to pull the dash or something.

OK - I was intending to use the connectors that are commonly found on PC peripherals, as they are quite flat, but those look good too - not too big.
Presumably, because the switching on that jack socket is only on the left and right signal wires, the common connector just ties all the ground wires together.

OK C_B_V - so your wiring looks like this?
I am assuming it has to because the socket has no way to break the Ground connections, only the Signal L & R.

Yep, only thing that I did different it's wiring the input ground to only one channel, I did not want to try wiring both because L and R grounds would connect to each other and I didn't know how will affect that to the unit

Well, if it is working OK like that, clearly no point in adding unnecessary connections.
Also this validates the labelling of the HU connections as "GND" and "SIGNAL" in that the GND connections are obviously genuinely common inside the HU else you would only get sound on one channel.

Well, as our friend Coolant says, there is a bit of a volume drop but nothing drastic. Now to tidy up the wiring...

Had an "Oh No" moment when the aux sound went fluttery and then failed.

Lesson - always engage the CD changer plug lock AFTER fully inserting the plug. :oops:

...but all you can see is a 3.5mm socket in a switch-blank!

The only difference is that mine is in a 2009 car so the blank is in a different position and the fascia is black.

About the only other thing I might do is to modify the phone mount left by the previous owner so there is somewhere to attach my Sansa Clip MP3 player rather than it flying around the cabin on the end of the auxiliary cable. The bracket is right next to the socket. Downside of the Sansa is that it doesn't seem to want to charge and play at the same time.

I also have a Satechi SoundFly MP3 unit that plugs into the cigarette lighter socket, which has both FM and wired output, but although it sounds fine, it has the most ridiculous Shuffle function that seems to create an internal playlist of about 200 tracks and only play those, regardless of how many files there are on the card.

Now here's a (perhaps) interesting thing.

https://www.ebay.co.uk/itm/New-Car-USB- ... 2665323520

If I am reading the description correctly, it's a board that takes USB sticks and memory cards and produces audio out at headphone levels. Looks about the size of the little cubby-hole at the top of an Edna's ashtray. Yet another possibility!

...there's one with Bluetooth too!

Actually, when I connected the Sansa, I noticed that the volume was significantly higher than any of my other devices, and that reminded me that on a lot of players and phones there is a volume restrictor set in software to keep the output below a specified level, for hearing protection - which is obviously NOT useful for line-out purposes.

I found the setting on this player (and my old Nokia 5800 phone, which recently died :cry: ) and it appears that the "low volume" issue is almost eliminated. I switched between Aux and FM and there was barely a step...and the FM was on Radio 3 playing a full orchestral piece.

Unfortunately the existence of this setting is dependent upon the device and the version of software loaded (Symbian and iPhone seem to have it accessible, Android devices either hide it or the phone suppliers' branded versions remove it) so it needs a bit of research to find out if/how you can override it.
