Back up camera
I agree with Mike. The same thing happened to my 2007 Murano after I needed to get a battery jump -- my screen went black, no back-up camera, couldn't turn on radio or HVAC. Brought it into my dealership who changed the battery, then they wanted to run a diagnostic (around $105/hr). I asked about the fuses, and thankfully, as it turns out, it was the "back-up battery fuse." Just paid for the battery and labor for that, and the fuse.
