Cracked Display Screen. What to do?

What was that phone / phone case made out of?

It you want to replace it with the same / original, the number 57031 on the bottom right is known as the "Radio Face ID" and they are all the same so it will be a easy remove old and install new. It's not the part number but you can search on eBay and find some that will work.

You also mentioned upgrade and iPhone / CarPlay, Crutchfield will probably be your best bet for easy installation and support. They can also make custom wire harnesses so it is literally just plug and play without needing to worry about soldering or splicing wires. However to keep the steering wheel controls and/or backup camera it gets a bit more complicated and need to look into iDatalink Maestro or similar.
