21 Harley Road glide special, been using android auto from Samsung Zflip plugged into USB for 6 months and from S8 phone for 4 months prior. Worked great except occasionally when I shut bike off and left phone plugged in I would have to unplug and replug phone in to get the Auto play to show up on home screen. Now the thumb volume control reverts to prompt volume when I shut down to refuel etc.. Only way to get it to media volume is shut bike down, unplug phone, restart and plug phone back in.
