you don't need to tie the KEY1 and KEY2, you can connect one of them or separately connect them to the regarding metal part from the 3.5mm jack .The black wire you 'd better connect to the Ground.
2.you can connect the cam signal wire( yellow RCA connector) to Video-in connector instead of CAM -IN connector back of the car stereo.And connect the power cable of the rear cam to the acc position instead of rear car light .And don't connect the wire which labelled "reverse" from the ISO cable.At last ,when you want to see the rear imgae,just click the AV-in app/icon on the menu .
