Blaupunkt Acapulco MP52 - Opel Astra interface

Hi,

Does anybody has the electronics/wiring scheme of 7607588510 blaupunkt - opel astra interface used to connect mp52 to astra's fabric remote control commands?

I would like to create it by myself if it is not to complicated :p

Thanks.

It is complex, as it uses a variety of precise resistor values to get the right commands to work.

Sorry for the late response:frown: Do you have the diagram for this or you know where can I find it? I was wondering is this interface made using only passive electronics or it has some active parts too?

Does Blaupunkt keep this in secret?
