How 2 add AUX IN in pre-2007 CD70 models

[Johnny-B]

Hello!
I need to do this modification on DVD 90 2006 Signum! Does it need to add some components in unit or only add pins in connector???

Could @Admin move this to the how to section? I would but don't have the option to

Right, as I'm getting this activated this weekend, I thought I'd post on how I've gone about it. I went off a mixture of the various pdf guides and also the schematic. Attached are photos showing of what component value I put where.

THIS IS NOT IN ANYWAY FOR PEOPLE TO COPY. As of yet anyway. If it works then feel free.

If anyone can spot anything they think will cause problems please let me know.

sorry for the photo quality, iPhone and all that

Look up the schematics for the TDA chip and see which one is the right hand input and follow it backwards until you find the issue..
