Car radio questions

[Cat966c]

Hey everybody, this is my first time in general discussion so take it easy lol. I was recently driving my car and I was coming to a red light and had my thumb on the touchscreen of my subaru radio. Well I came to a quick stop because the light went from green to red with no yellow.
So my thumb cracked the touchscreen and now it won’t respond to touch, but everything else works.
I called my dealer and they said it would be 1000+ dollars to replace the radio and code it and stuff 😱😬😬😵. And 135 if I bought the radio and they swapped it out.
I was thinking about taking the radio out myself (because youtube) and was wondering if one has to code anything or if the mechanic was just trying to get money out of me. Because I didn’t see anything to do with coding in the videos I watched.

Thanks
