Respuesta al mail que les mande:
Hi,
Sorry for replying in English as we currently do not have a support agent who speaks Spanish.
In the Aha app on the phone, you will need to associate the Amazon music account. See link
Linking Services to Aha. Now when Amazon account is linked to Aha, go to the Favorites page. At the top under Linked Services select Amazon Music. Here you will see tabs at the top like Playlists, Prime Stations, Popular. Select Playlist or any other option and you will see the music stations available. Open the one that you want. Click on the + sign to add that station or playlist to your Favorites. Now you should be able to see that station in your Aha Favorites and you should be able to see it under Aha Favorites on the car screen as well.
Please let us know if you additional question.
