Hello overyone.
I want to ask you advice what to do with following troble, that I made to my car.

I own 2008 Freelander 2 HSE with genuine GPS biuld in. A few years ago some company has retroffied aftermarket GPS unit that connects to OEM screen via GVIF. It works ok but yestoday what I found that a lot of cables are ander my glove box looks terrible I have tried to disconnects all and then make cables comes better way. No I don't have picture on my screen even from stock navi. When car starts I see LandRover logo and after I press Navigation, screen goes black. I can hear that touch screen seems to work. I can head press sounds and navigation voice, but no video. I tried to disconnects GVIF and connect blue video cable to screen without any adapter, same problem. Doesn it means that I have blown screen or what to do? I thoight it ca be bad connection but I tried 8 times nothing. Do I need to change screen or it can be repaired?
Thanks for any advice.

I found problem. Was smashed contact in blue screen connector.

Not an easy question to answer, good that you found it
