Tiene que ser algo de aquí, sacado del tutorial de la cámara
Module 6C Rear view camera
My camera came parameterized and pre-coded for A4 B9 and I didn’t need to make any changes here, but I’ll leave some instructions, maybe you’ll need them. Code according to your car:
Byte 04 – Bit 0 blocked to 1 = AHK
Byte 04 – Bit 1 to 1 = Parking aid front + rear installed
Byte 04 – Bit 1 to 0 = Rear parking aid installed
Byte 04 – Bit 2 to 1 = Parking Assist installed
Byte 07 – Bit 0 to 1 = Guides across
Byte 07 – Bit 1 to 1 = Guides parallel
Byte 07 – Bit 2 on 1 = Guides Trailer
Byte 07 – Bit 3 on 1 = Guides cross
Byte 07 – Bit 4 on 1 = Guides park steering assist installed
El byte 04, bit1 ponerlo a 0 para solo trasero
Yo cuando puse la cámara sin sensores delanteros, al ponerla se veía la imagen del coche y de la cámara, pero no las barritas de la proximidad de los sensores, eso solo con delanteros + traseros
