Can anyone identify this object?
We really shouldn't speculate, but it does not look like a panel piece for a door or window. Aside from two small warning lights on some models there shouldn't be very much.

This is very much speculation: Aside from the deep inset, which looks like it could have housed a CRT monitor, there are two holes for square aviation-style switches, and two holes, perhaps for backlighting, above it. The left hole looks very similar to an SD card slot.

Then again, it could have come from a boat or anything.
