I bought this head unit back in Novemeber, I just got around to installing it yesterday. I bought two (SCOSCHE VW01B and Metra 70-1786) and used the Metra harness to 1:1 everything, and while it works, there's a constant low hum and occasionally the screen will just go black, and stay black until a reboot. What harness did you all use? The harness that comes with the CP71W was also incredibly loose. I have an 04 with the Infiniti system.
