PDC and phone XC90 Probs

Hello together, actually I have not had any problems with my XC90 so far. However, two, perhaps not so important, details work a bit strangely. 1. PDC When inserting the R-range, the radio is not controlled by radio or CD in volume. The beeper works, but you hear it badly. 2. Phone For every call in the absence I get two messages. The first with text: “Call on mailbox…” The second shows the call date and the time, however, no further text. Who has similar problems and knows a solution. My friend is a bit perplexed. Thanks and greeting bkpaul
