Hi guys, owner of a 2016 WRX here with what I hope is a pretty straightforward question. The glass screen on my stock head unit cracked, and now the touch screen functionality is completely gone. I'm looking to replace it with another stock head unit (was going to buy another used one on ebay) but I'm curious if there is anything I need to watch out for - or is it a simple plug and play? I don't have a whole lot of experience manipulating car audio systems and wanted to avoid a major mistake if possible. Tried searching the forum and could only find info about upgrades. Thanks in advance for any help.
