Here’s a good video showing how to remove the Challenger trim to get to the head unit.
I removed to replace touch screen, using plastic trim removal tools, but still ended up breaking the upper right side clip. Pretty sure that one was defective from the plant for me. But super glued it back and have no rattles.
Definitely would suggest plastic trim removal tools and just taking your time and be gentle with increasing pressure; no need to apply brute force all up front.
