Hallo
Leider mein Frage in English, aber bitte in Deutsch antworten:
Hopefully You can help me. I have installed an Android aftermarket radio and it works fine. But I don't know how to connect the wiring to the steering wheel controls. On the radio there is a "key1" and "key2" wire, but how do I connect them, or one of them, to the wiring from the car? I have attached a wiring diagram from the radio.
Best regards
