I love Android Auto so much I never unplug my phone from my 2018 SE Kona. Previously I had a 32GB USB plugged in with all my CDs to play. Is there an SD somewhere? If not it would be a good idea in future models.
I don't think there is a slot for SD anywhere that I read. Looks like USB it is...careful though it mentions not leaving USB plugged in while starting your Kona...see images
