Ha I found this in my cup holder when I got my car. Not entirely sure what this is but I found where it goes. If u reach into the phone charge area, on the right side, closer to the shifter, you should feel a hole. This goes there. Make sure the open side is facing up, and the smooth side facing toward the front of the car. It slides in from the top then the top part you just push in. Due to where it’s positioned, you have to do it blind. Good luck.
I found this part on the charging pad shortly after I got my car. Took me a while to figure out where it goes, but yeah, there’s a hole in front of the shifter that it fits into. It hasn’t come loose in months, so hopefully it stays put.
could it be a cover for a slot where you can insert a key to be able to shift the car into neutral? Didn't that used to be a thing? Maybe the center console is the same as other cars in the Honda family that may have automatic transmissions?
