For people wondering how to get AA via wireless this is the steps to take:
1. Rename the hotspot of your headunit to the hotspot settings that HUR requires:
a. Name: HUR
b. Password: AndroidAutoConnect
2. Make sure your HUR is in the latest version, as of now its v5.2 from the playstore
3. On HUR, make sure you have wireless incoming enabled, its in the connectivity settings of the app
4. Go to your phone's playstore and download the app "WiFi Launcher", its from the same developer that created HUR, once it downloads, open it and it will ask you for a few permissions, make sure you allow those permissions since it won't work without them
5. Now, connect your phone to your android headunit's wifi hotspot you created in step one, make sure your phone connects successfully, after it does, open the HUR app and you should see "listening for incoming connections", at this point your phone should connect to your HUR app, it it doesn't, go to the "Wifi Launcher" on your phone and go to advance settings and click on "Start WiFi service manually", at this point it should connect.
Mine was working fine but than for whatever reason it's failing now, i open the HUR app and it seems like my phone will automatically connect but the HUR app flashes and it auto closes, not sure if someone has had this issue on their systems
