Has anyone parked their roadster outside for a few hours and had the odometer/range/amp display become pixelated? Had the roadster parked outside for 3-4 hours in a surface parking lot, I came back to the car and noticed that the display was grainy and pixelated. I thought perhaps it had something to do with the dimmer but this did not help at all. I thought for sure the display had went bad (pretty common problem with Mercedes, BMW etc). Went back to the car this evening and the display looked perfect. The only thing I can think of is the sunlight somehow caused the display to become pixelated. Anyone know if a good windshield sunshade for the Roadster? Probably worth the 30 seconds of effort to put up the sunshade to prevent this from becoming a recurring problem.
