Can I replace my aftermarket radio to a touchscreen?
 

I have a Chevy impala 2002 with a aftermarket radio with cassette player now my question is can I replace my old radio with a brand new touchscreen replacement? I’ve been trying to figure out what size touchscreen I would need to replace my old one comfortably but I can’t find anything helpful about it if you have any more questions let me know thank you!

this is what my radio looks like now
