Whilst I was driving along today my display clock decided to turn it's self on and off intermittently. I then turned on my radio, that did the same thing, but come up with a message stating "the park pilot is unavailable". 

It's seemed to have stopped doing this for now. Anyone experienced similar? Could it be faulty head unit?

Update, It's not happened again, I'll put it down to a software glitch. 

I spoke too soon it's just started doing it again🤣 a week later, so very intermittent.
