Hi all, wondering if anyone can help. I’m trying to get power to a carplay unit and not sure how to achieve this.

I’ve heard it’s best to connect to a switched live like the headlight or brake light or horn so it doesn’t risk draining the battery but not sure where to even start.

Would it be easier to connect a USB charger and just use that for the carplay power supply? Any help is appreciated
