I use this with my pioneer z110bt nav unit. I can leave the camera running while driving and full screen when in reverse. Basically camera is always on, not just when backing up and after 6 months it works perfectly. Lots of rain where I live too. Works at night, and rain/sun doesn't affect it. The visual lines showing distance is a great feature for backing up as well. I'd buy another one if I were to add a front camera or of this one failed on me. Offered and paid about $73
