Video interface for 2008 Lexus IS350

I have bought a Video interface for my 2008 Lexus IS350.
I use the VGA video input to connect my CarPC to the interface. I have tried different screen
resolutions but none fits the screen correctly. On 800x600 the image is shifted to
the right, on 1024x768 the top and bottom of the image is cut. What resolution should
I use? Are there any timings I can use to create a custom resolution?
Best regards,
Rodion
