Car PC in the Audi A8, where to with the screen?

Sea's people,

I am new to the club of the A8 and also to the club of the V8 drivers. When buying my car, I did not look at a navigator but rather looked at service certificates and cared for the vehicle. I have also been well informed about diseases before and am very satisfied so far. Unfortunately my vehicle lacks a navigation system, so I decided to install the whole right professional and build a car pc into the car, my biggest problem is now the location choice for the screen...... I only have the din radio shaft and get space problems, I am superior to putting the bedin for climate deeper, ie I don't put on the ashtray etc, and plant the whole down. Of course, I have to work on the complete inlay, and the root wood decor can't stay...... would model the whole with pale-fiber mats, and later with carbon foils nicely installed... Does any of you have experience with similar modifications? Good ideas for other positions of the screen would also be very much in demand. find the radios with extendable displays would only spoil the optics, that has fit with my audio coupe or also with my a4 still bitsl into the picture, but in an A8 I don't want to have such a thing....

PS: If someone is interested in something like this I can make a kind of instruction for the necessary parts/work, interesting is the whole thing especially in connection with the return cam, videos of fast driving, like e.g. the annual Quattro-Drift-Challanges with the first snow etc.
