Blaupunkt CD30 schematics wanted or info on adding aux internally

[waigy]

I've been researching adding an auxiliary input to the blaupunkt CD30 (manufacturers part number 453116246) in my 06 vauxhall corsa.

A handful of people have mentioned the possibility of connecting wires directly to the audio output from the cd drive inside the unit.

Does anyone have experience of doing this mod or does anyone have schematics for the CD30?

I'm not interested in any other way of adding aux including buying a CD30 mp3 or using an fm transmitter.

I found this, **broken link removed** which, I guess, is the mod, but you loose the CD.

Thanks, but that would only work on the cd30 mp3 which has aux outs at the back.
This is what I am after:

These guys https://www.gravitech.us/stja3brbo.html sure don't tell you enough info. There is a "Jack presence" ; who knows what that means. A contact to ground when the pug is inserted or vice versa?

But it gives you an idea. An external relay could be used to switch in the aux input.

A mount like that would be ok or even just long wires coming out of the unit to a jack plug.
I first need to find out how to tap into the left and right audio feed from the cd player and if it's useable as an aux.
In post number 4 here (http://www.vectra-sport.com/threads/cd30-aux-mod.97399/) Andre mentions this mod and makes it sound easy, but I haven't been able to get registered on that site as they haven't sent a confirmation email.

I'm struggling to find schematics for the cd30 without paying or doing a stupid survey.

FWIW: Cheap to play with, anyway" **broken link removed**

I also found this: https://www.nodevice.com/manual/cd30/get84250.html

and this: https://www.servicemanuals.net/ServiceManual/BLAUPUNKT/cd30/pos1/results.aspx It's the MP3 version, I think/

Quick searching landed e in quicksand so to speak. Blaupunkt was nice stuff.
