Arteon computer intermittent computer failure

Now and again, the computer / radio / sat nav and everything goes off and the screen goes black. The only warning we get is that the radio stops working and then everything else ceases to work too. Pressing buttons makes no difference, after a while, sometimes a minute or two, or five minutes everything comes back on. I have an iPhone 13 connected via blue tooth to the car.

Anybody else experiencing the same / similar?
