Hello @Roland_von_Unruh,
Thank you for your message.
At the moment, this behavior is a product limitation — in CarPlay, the Artist view only shows a limited number of albums and doesn’t yet support expanding the full list.
To help us better understand how important this feature is to our users and prioritize future improvements, please consider adding your vote and comments to the existing feature request thread here:
Roon ARC CarPlay – Improve way to find Albums/Artists
We appreciate your feedback!
