Hey joylove, i saw your post regarding INPA, I want to buy the cable i have a 323i 2000, OBDII 16 pin and 20 pin socket. You mentioned that i should buy usb kkl 409.2, i am only finding 409.1 on aliexpress. Could you advise me on what to buy? I need it for what i believe to be a k-bus problem, everything works in the car except the radio says disabled. I need a way to tap into the kbus to see what's going on. Can you help me with my problem il put a post and send it to you
