I am completely at a loss with this one, which probably means that either [color="#008000"][color="#00FF00"]Td[/color][/color] or [color="#0000FF"]Du[/color] will instantly know the cause... hopefully:
A few months ago, I cloned one of my GO710's for a friend who had an old, non-updated, un-tweaked one. My definition of 'cloned' is that I updated his bootloader and navcore to match my own (Nc 9.205 with b/l 5.5250), copied my SDHC card (minus .bif), patched it etc .... and everything seemed to work exactly as mine does, with all the whistles and bells.
A few days ago, he informed me that one function did NOT work ... it hadn't done so since the 'upgrade' I'd installed: it will not switch to night colors or at least, it will not STAY on night colors! You can try to change it from day to night either by menu selection or by voice command and it changes momentarily, then reverts back to day colors after less than 1 sec. I've compared all the settings of the two units and as far as I can see, they match and mine performs faultlessly.
Does anything spring to mind guys? otherwise my next step is going to be to compare file contents when I get time over the weekend.
Condiments of the Seasoning to you and the NT Team by the way...
