I recommend replacing the radio with a more modern aftermarket unit.
Crutchfield is an excellent retailer that’ll let you pick out a radio and they will build the harness for $25, so it’s truly plug and play. Install is very easy, takes 20mins.
My favorite is the Sony XAV-AX5000.
JDM radio filler panels can be found online, they look much better than the generic ones:
