Hello,
I bought an external Navi with an Igo Navigation (Basarsoft). I have the following problem.
When i driving the map screen disappears and is replaced by a black screen that shows the current time. I found out this is a screensaver. I found some settings regarding to this, but i couldn't deactivate it completely. It now appears and there is a Power button in the corner. If i touch it, then the screensaver disappears ...
