Hey, good people. I have a question. So, I'm in the process of putting a Pyle PLMR18 aftermarket radio into my 2001 Pontiac Grand Am but hit a little snag. I need to remove the outer part of the faceplate in order to put the radio in a harness. This is the only problem I'm having right now. I've been trying on and off for about 2 hours without any luck. What is this part called and how do I take it off?
