In earlier DAB+G versions this might be called “Presets”. To add a DAB radio station to the Favourites list, you need to use the fast forward function in the Now playing menu. Fast forward is that if you press and hold the next track button (if you can’t reach this function please check the user manual of your car – every car works different). After you added the stations like this, you can reach them if you go to Favourites in the DAB stations menu. Here you can delete all the favourites if you choose the “Delete favourites”, or you can delete them individually if you press the fast rewind (holding down the previous track button).
