Eliminate a common Android Auto headache with this minuscule gadget

Several months ago, I rented a three-year-old car from a major rental company. Driving out of my city absolutely requires to-the-foot directions and mapping, but I struggled to connect my phone to the head unit's Android Auto Bluetooth connection for nearly ten minutes. Exasperated, I fished a USB cable out of my bag and resigned to a wired tether. When it worked perfectly, I suddenly realized this model year 2022 vehicle didn't support wireless connections. I was floored.
