Let me show you how to install a frameless auto-dimming Gentex 1427 mirror that has Homelink 5 capability and a built in compass for under $100 dollars. You can get this mirror used on eBay for cheap. Just search for a 2017-2022 Subaru Impreza rear view mirror with homelink.
Alternatively you can buy a brand new version of this mirror that gas a green compass on Amazon here https://amzn.to/4pJvEkJ
