I'm looking at getting a back-up camera and have ran into an issue. I can't freaking remember if my headunit (iva-d300) automatically reverses the image from a backup camera, or not. I'm pretty sure it does, but can't find my manual or info on the net anywhere. I believe the d310 unit is the same for the most part, so if anyone knows about that unit, it would likely be the same as mine.
