The computer was rebooting every time I started sd. The solution was the screen. I was testing sd on my desk with a old crt. When the pc was warm and I then started sd (the graf engine seems to draw a lot of power) the power supply (atx-m2) dips en resets the computer. I read somewhere to change the capacitor #c35 from 20 to 10 nf? Maybe I will try this.
The second problem stays

I can not start navigation. It seems sd want to start navigation north America but I have installed Europe (since I live there its more convenient

) Does anyone know how to change this?
The last line of the log reads:
INFO: MessageBox:
Initializing...
Please wait while navigation initializes.
