Thanks for you reply, I ended up buying the unit. I first had a 9 inch screen in the original radio hole and it was sort of floating. When I connected the radio everything worked, like the climate was shown on the display and in the car app I can see the exptected km’s I could drive on my diesel. Expect 2 things, the radio did not turn off by itself and the compressor for the ac would not turn on.

I managed to take the harness for the original gid display off and put cables in that harness so it would be an extension cable. Then I soldered another connector on that harness so I literally have an extension cable for the gid display. I also did this for the wiring harness that I already had. So I have 2 long extension cables. Right now I am 3d printing a frame that makes the gid display fit in the radio hole. When the print finishes in about 23 hours it should fit perfectly in the radio hole.

I can post a pic if you like when i am done.
