What part is this?

[NOBODY]

My medium-sized dog was in the back cargo area (3rd row was folded) of my Palisade this evening. I left her alone for about 45 minutes and came back to find her on one of the 2nd-row seats with a chewed electric part and pieces on the floor.

For the life of me, I cannot figure out what this is. I couldn't find anything visually in the cargo area or 2nd row that looked broken/torn. When I drove home there were no warning lights or errors, and everything seemed to work.

Some notes:

• 2020 Palisade Limited
• Must have been something accessible by a dog from the cargo area or 2nd row
• Has some kind of sensor or possibly a speaker
• Has a bracket of some sort
• Appears to have compartments for non-standard batteries (looks empty as I didn't find any)
• Internal circuit board
  • Has a micro USB port; I didn't find the other end, but I believe it is what the sensor connects too
  • Has a chip with the marking "FM9688AA". Googleing gives some results on Allied Express (Asian electronics marketplace) for a SOP8 integrated controller. Reviews say that it can be used as a replacement of some kind of part for wireless headphones and that it might also be a transmitter of some sort.
  • Has a designation of

Guesses I've researched

• Some kind of temperature or climate sensor (but all of those look to be in the bumper area or dash)
• The rear occupant alert sensor (wrong shape)
• Maybe related to the intercom (driver talk)?

Guess you bought the vehicle used, no? Sounds like a part that was laying around somewhere where the dog caught it. Does the vehicle have a hitch? Could have been an electronic brake controller not installed yet. But if it's an 'Ali Express' part, it doesn't belong to the vehicle, so I wouldn't worry too much about it. You could try to contact previous owner if it was a private sale. Good luck.

Anything found in the interior that belongs to the car will not have a battery compartment. Must be some kind of portable audio part or something for portable gaming. A picture would help...........................
