I've been using this app with no issues for about a year then suddenly it's disconnecting at random. I can be parked, driving, stopped and AA will just stop working as if the USB isn't plugged in. It seems to be battling the bluetooth connection, but when I turn bluetooth off on my phone AA turns it back on! I've updated and reset everything on my phone and my car system to no avail. I've changed my USB cord out too. Plus it's super dangerous while driving using GPS.
