I have the f900 bt and recently just installed a pioneer back up camera. I followed the instructions and wired the camera to the switched power source. At first, I had to turn the camera on through the settings. Then it started coming on at start up and I could get it to go off by hitting menu or map. Then I couldn't get it to turn off at all. I even disconnected it. The camera screen still stayed on but was just black. I eventually had to reset it with the camera disconnected and that has seemed to work.
I am going to try wiring it up to the reverse light wire. So that it will only be on when the lights are on.
I am wondering if anyone has had or heard about this problem before and if they figured out what it was all about.
