Been through the user manual and I don't think there is a way out but I noticed today that the ambient lighting does not work if the headlights are not turned on. I find that a bit weird as in my other cars (e.g BMW) the ambient lights work in the day too so if going through a tree lined street you can actually see the ambient lights.

IS there a setting to turn the lights on so that they stay on without being connected to the headlights?

I would like the ambient lighting on during the day and have looked too and can't find away, it does look like that the headlights have to be on too...... 2010 RR 5.0 Autobiography

There's a few other anomalies like the stealth won't turn the bottom screen off unless its dark so guess similar thing.

Can't change to seat heat/cool mode when the bottom screen is on certain screens either.

Sometimes when you set the seat to cool it just flips to heat instead for no reason.

Lots of small bugs here and there

My bottom screen doesn't turn off at all in stealth mode only the top one.... 2010 RR 5.0 Autobiography

Should do at night time when the lights dim a bit
