I have the same problem. I just press the power button off then back on and it works as normal. Mine used to also just cut out while driving and play nothing until I turned it off then back on. Took it to my dealer and they reset everything and checked for updates, none were available. The reset fixed the cutting out while driving but it still doesn't work at least 50% of the time at start up. When I took it back to the dealer they said that they could not replicate the issue(of corse) so they could do nothing for me. They told me to take some videos when it happens and try to bring the car in when it's doing it but I haven't bothered to take it back.
