Without a picture I doubt many of us know what yours looks like or where it's located, but:
Mine doesn't have a faceplate, it has a surround.
It just pops out and will likely be of no use on your new install.
To remove the radio from the mount, if you don't have the tool, use a butter knife. Stick it in the side, along the top edge, and slide it down. It'll pop the clip.
Then do the other side..
Mines halfway out right now awaiting professional replacement on Monday.
You can see the little tabs on the surround bezel. Just a light pressure disengages.
You can see the half round clip on the frame that clips into the hald round indent on the radio. Just slide a butter knife in and it unlatches. Slide the radio out with the butter knives still in place.
Three minutes to find butter knives, 20 seconds to remove the radio.

If yours is completely dead and you're low on funds, my good 2018 radio will be probably available for free. Pick up at the Grand Canyon or at Pechenga for the west coast meet-up.(Pechenga WI require a trade... Ice cream, a dog turd shaped like George Washington... Any trade.)
