Hi

The screen blanker function works ok, it is set to be sensible at 90% and clear display.
The 'sleep' mode doesn't depend on any kind of time rule. It is completely random, sometimes every 2 or 3 minutes, sometimes never, or 3 times per song.
When it comes on again, display shows the usual screen, no battery icon. When it is plugged at home, I use a powerfull 13v. source witch I don't think to fade volts... and the problem is there (well, at home I can continue listening to it, since it doesn't stop the RCA outs, only amp 'on' signal)

The different screen when in AUX mode, I had many months without seeing it (since I updated the soft) but now I can see it many times:
Usual AUX screen is my favourite visual. The other screens are very similar to player mode.
The 'strange' screen when it reboots or when it 'wakes up', has a big horizontal volume draw, and a small 'gain' vertical volume draw at the right side. It automatically increments the gain when the source is low.
I don't know when I can turn it on or off, it comes up whenever it wants...
Many months ago, I suffered several reboots when in car, and after them I got this screen as well as no way to view my visuals. The way to resolve it was to pull out and in riocar into sled.
The other difference both when it reboots or when it 'goes to sleep' is the frecuency of the blue led, wich must blink every 15 seconds but fades in and out when riocar is in this strange mode...

As you see, I'm completely lost, and my english is not as good as I'd want... I hope you to understand it

Thanks a lot:

Miguel.
