PioneerX1 version 3
Got the image transfer working after buying a CD-RW. The "desktop image" on the navi unit is 1440x700, stangely Pioneer state that the screen is 1440x234 pixel??? and 14,4x7,6cm, first I tried 1440x234 then 1440x760 but that was not right.
I then tried 1440x700 as it seem the 1440x760 was approx. 10% to big in hight. Also the image was applied 0.65 gamma correction to get the color to match.
