... Now even when driving the crazy things switches from the radio screen to the back up camera. You have to touch the screen to make it go back to the radio screen only to have it flip back in about 15 seconds. We tried just turning the back up camera off, then the crazy thing flips to just a black screen. Does anyone have any suggestions?
As a point of reference, my Pioneer unit is wired from the purple/white wire to the +12V reverse light wire. The camera has 3 wire connections--video RCA feed and a red and black lead. Black to ground. Red to the same +12V reverse wire as the purple/white. (Obviously you can splice into this connection near the Pioneer unit--you don't have to run wire all the way back to the back-up light.) This set up should only allow the camera power when the transmission is set to 'reverse', and the Pioneer unit should change screens only when 'reverse' is chosen. However...
Upon connecting the battery, I had the exact same problem as Parsond. The Pioneer owner's manual is a piece of crap. I didn't have to rewire anything. Obviously, your unit was working as desired before, so I don't think you don't need rewiring, either.
I solved my repetitive black screen by changing the "MUTE" instructions. The default instruction is incorrect for our needs--rear viewing on only
when the transmission is in 'reverse'. (In the path, source/settings/mute--'MUTE/ATT' is the option about halfway down the list. Change its' instructions from the default "MUTE" to "OFF". ) Bring up the SOURCE/MENU by pressing the center (round) button in the middle of the selector button 'ring'. Touch 'Settings' at the bottom of the screen and find 'Mute' on the list. Now change it to 'OFF'. (Leave the REAR VIEW CAMERA setting at "OFF". [this is not an instruction to your camera, if you turn it 'ON', it's an instruction to your Pioneer unit to turn on viewing--you don't want that--the reverse light wiring will override the camera screen setting]).
That should do it. (Page 67 of the instruction manual claims holding down the "MUTE" button will kill the black screen... that's the hint I needed to find the erroneous default command. It did take a lot of pawing around their software... Like I said, the Pioneer manual is junk.)Edited by moredes - 11/7/12 at 12:52pm
