I get a very strange prob. My unit sometimes, when i switch it on, lose the language settings (go back in english), and also the colours illumination settings go back to blue! I don't know why... updated with last firmware, battery seems ok, power connection it's ok also.... I happens randomly. There is a fix?

I got the same. Did you fix this problem?

are your stored music fm/am chanels lost as well? if so sounds like a loose constant power wire

I get a very strange prob. My unit sometimes, when i switch it on, lose the language settings (go back in english), and also the colours illumination settings go back to blue!

This happens to my F700BT as well. The only thing to reset is the illumination colour, i.e. all cables are ok. It's driving my crazy and applies to both Hybrid 4.01 and 3. I've tried holding the memory buttons and calibrating the screen, but on every second reset the horrible blue colour is back.

I imagine a workaround could be to alter the default illumination colour, but I've yet to find out where they are stored. Anyone with ideas?

Thanks!
