I saw a topic from a few years ago. Looks like it hasn't been solved but maybe I'm overlooking something. 

Is it possible to see a full playlist in deezer Android Auto app? If I click on a playlist it just starts with the first song and I can't choose any song manually. 

Just switched to deezer from Spotify and there it first opens the complete playlist and you can select your song. If it's not possible I've to switch back to Spotify because this function is absolutely a must.
