Update:

I got brave and disassembled the Nav unit. I got the screen out and off the logic board, but I am having trouble finding places to buy the screen. eBay and google are coming up short. The part number of the screen is a Sharp LQ058T5GG06

Also, would there be any chance that I would have to replace the circuit board as well?
 
Hey Turns out I'm in the same boat as you. I found a company on ebay that will fix it for like $350... But I was hoping if you had tried to replace the LCD yourself to see if that is the solution. I am kinda leaning toward it is. I found a site that sells for $150. But am still waiting whether to buy. Also put in a few inquiries to some China Suppliers. What have you come up with.

i just got the same screen you are seeing on your unit. wth....did not expect this from a $25oo head unit myself, would have thought the unit would last more than 3-4 years. if you found someone that fixed yours, let me know, it would be greatly appreciated.
 
Hi guys.. did anyone found the solution for the messed screen problem? I was at dealer today and wanted to buy commander overland 2007 but NAV screen is same as what you have. Not sure that I want to buy a truck if cannot fix it myself..
 
If you saw the vehicle at the dealer, tell them you want $$ off or they need to fix it. I wouldnt buy it unless they did something...
X2... Tell them you want to buy it if they will fix the screen.
 
I just purchased an 06 limited fully loaded Commander a few weeks ago. When we test drove the vehicle the dealer told us that the screen was working. However, it was showing the exact lines that were in the photos shown in this thread. We ended up buying the commander under the condition that they would pay to get the screen fixed. Since we purchased over 3 hours away from where we live, the dealership ordered a new unit and shipped it to a local installation shop. We had the new unit installed for free about a week ago and this thing is now working great. From my past experience with installing a custom carputer and touchscreen in my G35, the lines on the screen looked like a cabling issue. Some of those wires that plug the screen into the circuit board have very flimsy paper thin contacts on them. If one of those isn't seated completely or works itself loose it can ruin that contact from sliding around and will result in those weird lines on the screen. PITA to try and fix, best solution is to either let a professional fix it or order a new lcd for the circuit board.
 
OK Guys! As promised, posting my findings…

I have bought a used screen from eBay for $60 with the $20 shipping. The guy I bought it from swore that the screen is in perfect working order. I have received the screen last week and on Saturday morning took off the bezel and removed the control board with LCS screen from the NAV unit.
I have brought board and screen home and removed four screws which hold the screen to the control board. Then I have noticed that one pin from the screen is welded to the board – I guess for the ground (see pictures). Using a small welding tool I have detached the screen from the board and the same way attached the new one back to the board. I took it back to the car plugged to the unit and it worked :):):)… The whole procedure took me a little bit over one hour. I have attached photos to the post.

Congratulations ! Glad you got it fixed.
 
Mine is doing the same. Did any of the buttons stop working on yours? Only 1-6 work on mine.
 
Another victim of the dead screen....

Just bought my 06 XK 12 days ago, screen was fine until this Saturday :( In reading this thread of posts, it seems like i can replace the LCD. DOes anyone have a source for the screen?
Might it be worth upgrading to MyGIG??
