What is involved?
It looks super easy FOR MY 2016 ZX225...
remove faceplate screws ....
then lift out faceplate with 9 inch attached...
detach unit from cable plugs...
drill new holes in face plate for 12 inch...
attach the 12 inch with 4 screws from the 9 inch...
IS THAT THE WHOLE DEAL???
Hope to do it late today or tomorrow so need to know...
dealers are swamped for a week.
