I hav a Premium Spotify account. I am able to create Spotify playlists on my iPhone, and they do show up on the Tesla, but it is easier to create playlists on my PC.
So, after I create a playlist on my PC, how do I get it to appear on the car?
Syncing between phone / pc and car for spotify seems to take some indeterminate amount of time, at least for me. Also, if you add a song to a playlist on phone or PC, it seems to take some random amount of time before it shows up in the car. Additionally, at least for me, the playlist in the car does not always show all the songs that are actually in the playlist (showing on other sources).
In the US, playing spotify requires a premium account so there is no access at all through the tesla interface to a "non premium account". I have no idea how that works internationally however. If your location under your name is "southhampton, england", you should likely ask this question in the UK and Ireland subforum, because spotify access may be different there than it is in the US.
Try, doing check whether your car has the latest 10.0 version. Try and connect the Wi-Fi, and the update should happen automatically. Get the Spotify Premium subscription to be able to listen to the songs
On the screen, click on the music icon. It will be there in the bottom row. Now, click on the Spotify option. You will be redirected to a new window. Here, you will be asked to log in. Please note that Sportify's free account will not work with Tesla
You can log in by choosing the Tesla account. This way, the Spotify Premium account will be linked automatically. Your car's audio screen will display the Sportify account from where you will be able to choose the songs, playlists, stations, and albums.
After the setup is completed, you can use the voice command feature and ask Tesla to play any Premium Spotify songs that you want.
It is to log in to the Premium Spotify account, and from there, you sync the playlist to the car. The rest of the functionality will remain the same. However, Tesla won't allow you to create new playlists
