I got my Phantom 2 Vision + the other day. I was using it with an iPhone 5. A couple of minutes of flying the preview image stops updating and turns to grayscale, with no error messages... just stops updating. I switched over to using an iPod 5. Same thing. I even tried just carrying it around the house with the remote right next to it. Same thing, after a minute, it stops updating the FPV and turns grayscale. Anybody else seen this behavior and/or know what to do to fix it? I'm running the latest version of everything.
