After 3 weeks delivery I've got my CA-R-PI.017 !
First from France to Spain, where lives my cousin, next from Spain to Poland.
The only shop where I can find CA-R-PI.017 doesn't send items to PL.
First of all - big thank to you jwq - all your advices were very important and precious!
I've connected everything like you said and it's working like a champ
6 buttons from steering wheel is working.
All speakers play sound.
BOSE amp is working (yes, it's a little loud, but for me it's quite alright - my new headunit has 0-40 volume level, on 10 music is playing loud, on 20 very loud, on 1 it's almost silent, so there is no problem with Bose amp for me).
Bluetooth is working. The only thing is that I finally have used microphone from my headset instead of buid-in-car. All pins that you gave me is good (colors of cables in D connector and that connected to the microphone are the same), but I suppose that original microphone is too strong/weak/different/sth for my new headset. Or it's not working at all. Never mind. I've mount new one near speedometer. It looks not so bad.
Another thing is that I must use antenna connection converter (see below).
Nevertheless everything is very nice now, I'm happy that this is over
One more thing. I've found n the Internet (see image below), that I must modify my CA-R-PI.017, changing cables layout in C connector socket.
I've tested connection without this modification and all buttons works fine. So - it's not necessary for me.
