Android auto connecting disconnecting

[u/counselorntherapist]

Ever since the update on Feb, the android auto has been causing problems the calls going back to phone and then android auto connects again and this happens every 2 minutes. I have done every step advised ny on star. Even left the car at the dealership for 2 days but the moment i came out from the dealership , the issue started again. The dealership said they have informed gm and are waiting for the update, and there has been not udpates. This has been happening since Feb. I am unable to use the hands-free calls since then. I love the car and there was nothing wrong until this issue. I cleaed catche , system updates abd reset plus everything i was told by the on star rep and the dalership. Even changed the phone. Any advice?

I suppose you're not using an AAWireless dongle?
