Many cars and head units support wired Android Auto and Apple CarPlay, but compatibility with wireless Android Auto is more rare. There are a few adapters to rectify that problem, and one of them is 20% off for Amazon's Prime Early Access sale.
The AAWireless adapter is now on sale for $71.99 on Amazon, if you have an Amazon Prime subscription, which is a discount from the typical $89.99 price. However, the adapter hasn't even been in stock reliably for the past few months, due to demand outstripping supply -- if you want one, get it sooner rather than later.
AAWireless Adapter
This compact adapter adds wireless Android Auto to any car with wired Android Auto.
This adapter connects to the USB port from your car's entertainment system, and creates a virtual wireless Android Auto device for your phone. The result is that you can use Android Auto without taking your phone out of your pocket, as long as your car already has wired Android Auto and you have a supported phone (any device with Android 11+ and select older phones).
