Unfortunately I don’t
I know they removed the trim and added the felt tape. If I had to guess, it was probably to the area of the clips.

 

I'm really not sure as sometimes I hear it and sometimes I do not. And it's at the stage that it really isn't all too annoying yet. I'm just going to hope it goes away on its own.

 

I have one rattle like that now I'm still trying to track down. Like yours, the rattle doesn't happen all the time. Touch to pinpoint it.

 

Long Term follow Up:

After taking the rear cover off and messing around I settled on the interface of the bottom of the screen and the top of the dash as the culprit. I started buy shoving a business card under the corner (for me this was the passenger side corner) and the rattle was gone for about a month. After feeling like I had this solved I started looking for a more permanent solution.

I wanted something low-friction and that would last nearly forever and not have any interaction with the weather (paper can swell) and eventually I thought of this:





Not this item per-se but the remnant-punch-out piece (oval part where hook goes) from hang tags. I used to work retail as a teen and randomly thought of this after searching for sheet plastic in whatever "mil" thickness I would need. You could still go that route or order something along the lines of what I posted above and cut out a piece, but what I used was FREE! I just looked for one on the floor of the hardware store I was in when I thought of this

After getting the part I needed for this "fix" I trimmed it down a little with some scissors and then shoved it under the right-had corner of the screen. No more rattle! I left the piece slightly long so I can remove it with something like tweezers if I should ever need to, so this is easily reversible. That part of the dash is recessed too so you would never see anything.

 

I took a picture of where/how the plastic piece was installed in case anyone needed the reference.
