I want to buy an aftermarket stereo for my Toyota Corolla 2018 SE, and on some website to check compatibility, I have the choice of a 6 inches, or a 7 inches stereo. I really don't know what this measure is, and how to determine which is correct.

How to check the radio size of my car?

    Take out the existing radio and measure the hole. – Solar Mike Aug 12 '19 at 16:02
