This is one of these projects that I never finished. I managed to hook up the Jaguar navigation unit to the Realtek LCD controller board and in turn to an old 14″ laptop screen.
I had to tweak the Realtek firmware a bit to accept the video signal from the nav unit, but you can see it was working fine.
The imaginary goal was to replace the LCD screen in the factory unit with a better resolution screen. However, in the process, I was not able to find anything I liked with a side that would fit the Nav unit and would not require major surgery.
In the end, it was a cool thing to play with, but never saw the light of day. Here are a few more pictures of the Nav UI.
As you can see the 14″ screen does not have the correct aspect ratio – the circle is a bit squished.
Here are a few pictures of a screen I was considering as a replacement of the factory unit, but in the end, it was just a bit too big.
