Stu, I have the Avic Z1 with a backup camera and steering wheel controls. I just purchased the back up cam from Amazon.com, it is a Pyle View PLCM22IR. Only having used it 2-3 times since having it installed....it works great!! Clear and does great at night too. I had bought an Axxess ASWC steering wheel control because of all the good reviews I read on another forum, but when the installer saw it he said they've replaced several of those and he suggested I send it back. He used a PAC SWI-RC, so far so good. Hope this helps.
