I have set up Echo Auto in my car. It has to be connected to my iPhone to work. Alexa responds on the Echo Auto. However, when I give it a command to play a song on My Medis, it says it is playing, but to sound comes through my car speakers.
Also, when I check "My Alexa Devices" on MY Media, it shows my connected Echo Show and "Alexa on the iPhone"- it does not show my Echo Auto.

What gives?
