But is the 2011 Acadia slt associated with Bluetooth? Not all cars can connect the phone via Bluetooth, but you need an AUX cable. Even with an AUX cable, it is much more convenient because you don't have to wait too long to connect via Bluetooth. On my car, both connections are possible either via Bluetooth or AUX. But I choose to connect via AUX because the connection is much better, and the quality of my music that I put on Spotify with the help of streamingfamous.com sounds much better, haha. So you don't have much to lose.
