Sorry but I dont speak German...
Hello, recently after an enormous rain when I went to the car and started it, the navi screen didn't show the items: navigation, bordcomputer and telephone, and so when I when to the MK3 in the trunk I saw it was all wet... And when I tried to take it out, the water come out about half a cup... Then I dried it out very well, but it never worked ever since...
Now I am about to buy a used MK3 computer at ebay but none of the several sellers I've contacted know if their MK3s will work on my system, which is a small monocolored radio navi screen like this: http://i22.ebayimg.com/03/i/08/c6/fa/28_1.JPG
And the MK3 they have for sale are all for 16:9 or 4:3 colored screens...
Should I buy it? I didnt want to waste 260 euros...

Another thing I find strange is if (apparently) only the MK3 is malfunctioning why the items bordcomputer and telephone dont show? The bordcomputer still works perfectly on the odometer...

Anyone could help me?
Thank you.
