Hi everyone. I'm new here.

I bought a Sony Cd-player CDX-GT424U for my Audi A3 2002 last week. But i don't know how to replace my old Radio with new Cd-Player.

I bought an Active system adapter from Ebay. But maybe it isn't a right one.

There aren't Can-L and Can-H pins in red connector of the adapter like in connector of my car.
Is it the cause, that the adapter doesn't work? And when i use this adapter, i can't hear the sound from the behind speaker.

Red connector's image:



Can you tell me, what should i do to make the behind speaker work
Maybe i should buy another adapter. But i don't know where.

And i have another problem.

I don't know what happen with my car. When i turn on cd-player without starting of the engine, the cd-player can play only about 30s. Then it turns off and I heard sound pip-pip-pip from the speaker.
When i start the engineer, the cd-player works fine.

Thanks for help!
