I found on the web some answers regarding a calibration problem; so I followed the steps posted in these topics with no success. Then I changed the screen and also after that the situation didn't change. Do you think it could be a firmware problem? I'd be grateful if you could give me a hand. Sorry for my bad english and thanks for your attention
I think it could be the Bootloader because this will controll all the hardware.
With your last update, I suppose you did a Navcore update too ?
When you did it could be quite possible that there was a file "system" in that Navcore
Any idea which Bootloader you have now and which before ?

Goodluck anyway
