Strange Happening with Display

Hey all, something strange happened the other evening while driving. I'll just lay down the facts: I picked up my kid from class. When we got in the Prius there was a good song on and I cranked it up. He complained and I turned it down kind of fast. We drove to the street. It had rained earlier and there was a puddle at the curb. I slowly went through it and into traffic and accelerated. The music stopped and I looked at the display. The back up camera was on and I was looking at the road moving behind me. It flashed a few times then went black. I pulled over and turned off the car. Turned it back on and all has been OK since. Just weird that it would do that all by itself. I mention the rain and puddle but I didnt "blast" through the water. My wife had dropped him off about an hour earlier and she probably did blast through because its a tough left turn. Any body else ever run into something like this?
