There's no Wireless AA on the '21? My '22 has wireless AA, I can't imagine they just rolled it out in '22.....I dunno, maybe they did.
Not that it's ever as easy as they say, but Wired connection:
Wireless connection:
Few tricks I learned:
1. Wired connection is going to be more reliable.
2. Wireless connection uses both BT and WiFi together. The BT is only used for the handshake, WiFi handles the heavy lifting.
3. If you are trying to disconnect completely, you need to disable BT and WiFi at the same time, or one will turn the other back on.
4. You should uninstall and re-install AA on your phone to make sure it's the most up-to-date version.
5. Battery Saver on your phone will cause issues. You need to either disable Battery Saver or add an exception for AA on your phone's Settings.
6. On my phone, AA seems to take a lot of battery and the phone gets pretty warm. Wired is best to keep you charged on long trips.
If you want to ditch AA and use the Bluetooth like an older car, I believe you only need to uninstall/disable AA on your phone.
Once you re-pair your phone to your vehicle, it
should just be voice and music via BT.
