2 questions about my new Volvo V60

Hello Volvo friends, I’m now happy in the new V60. Have a lot of fun. Have everything except heatable rear seats and Sound Premium. I can’t understand or find 2 things as a tech fan! -I turn off the car with the radio, ignition, switch on the radio or the stream from the Eifon again at the next start of the car. So I mean really. The sound is to be heard immediately about the boxes. But I don’t want to and can’t understand it. Have all the settings looked through but can’t find it. -How can I see in the sense, when e.g. the brakes down, the next HU is attached or how the oil level is? The dealer said it will be displayed when it is. But in the Volvo on call you can also see it on the iphone! But what do Kd. without Volvo on call? Otherwise everything is understandable. Thank you very much.
