Hey good to hear you are getting into it. I have the saab park assist thing and frankly, I didnt want to spend the time and bother installing a rear camera. unfortunately I cannot assist with that. From the looks of what you have bought, you are all set. I dont know what stock audio system you have but I think people should be buying the RCA kit because if you dont, you are using the built in amplifier of the radio to send a signal to the amplifier of the car. the net result is that on volume 1 or 2, it will sound waay to loud. Its best to use the RCA preamp outputs on the back of the radio however the harness doesnt include that as an input. I ended up soldering in some RCA cables, perhaps I should make a thread about that.
