This only-such-device-on-Earth just got back in stock: USB C Splitter for Android Auto / Apple Carplay by Rohan Koripalli on Tindie - https://www.tindie.com/products/rkoripalli/usb-c-splitter-for-android-auto-apple-carplay/
I got one a couple years ago to separate my phone's USB port into a data cable that goes to my Naviplus Android Auto and Carplay unit, and a power cable that goes to my Power Delivery output from my aux battery. So I can actually charge at max power (up to 100W if my phone allowed it) and get wired Android Auto, which is truly awesome for music quality in the 200.
This thing actually works and is really tiny. You just need to play around to find compatible cables. I broke my splitter a few months back and was ecstatic to see it back in stock. Great solution for anyone stuck with inadequate USB charging while using wired Android Auto or Carplay.
