No native wireless AA in Sync 3.x. It’s only available on newer vehicles with Sync 4/4a. Need to use an aftermarket adapter such as the one CyanLabs linked above.
It’s not my adapter, it’s made by Emil Borconi and his team, He is someone i have personally spoke with and previously helped assist with some troubleshooting on a Android based stereo before i got my Ford car.
I know this is an old thread, but I wanted to let you know that the Motorola MA-1 is now available in Argentina through the Motorola’s Online Store, locally.
With this, you will achieve Wireless Android Auto.
I’m not sure if you already bought another dongle, but if you didn’t due to imports issues or something like that, then this is a good opportunity to get one.
