The Pioneer head unit is a great upgrade, it adds Apple CarPlay and Android Auto, as well as a number of other features. The amplifier is a great way to improve the sound quality, and it allows you to retain the standard subwoofer. The dash cam is a great way to record your driving, and it can be a lifesaver if you ever get into an accident. The auto fold mirror module is a convenient way to fold your mirrors when you park, it can also help to prevent theft. I’m really happy with the way this build turned out, it’s a great way to improve the functionality and performance of your WRX STI.
