Dashboard lights and nav screen flickering

Hi Guys,
On some morning while driving to work, I see that my dashboard lights flicker a little for a short while. I didn't pay much attention as it was not doing it very frequently.

This morning I also see some slight flickering on my Navigation screen.

Is this the signs of something breaking down??

The car is a 2008 750LI with 30,000 miles on it.

Any comments would be appreciated.

Thanks,
Anthony
