On verizon with the g4, both phone and radio have newest updates, and i had to turn on usb debugging in the developer options to get AA to work, but i also found another issue, after it worked the first time when testing it, i went back to use it the next day and it didnt, as i was going to unplug the usb cable it shifted just enough that it started working. i replaced the cable with a new one and have had zero issues after. So if you have any problems, wiggle the cable attached to the phone. Never know, it might work
