I noticed that most of power consumption during navigation is due to the display and often you drive ten minutes without the need of looking at it as there are non turns to do and you just have to follow the street...

It would be very nice to have a power saving option that, when enabled, automatically switches off the display if no turns or navigation messages are foreseen in a short time and automatically switches the display on when approaching a relevant point (e.g. the criteria could be related to those of spoken messages: when it is about to speak, just turns on the display shortly before)

I wonder that such a 'simple' feature is not already implemented...
