Android Screen DIY Installation for Audi A5 2009-2016

[@PantelimonAndrita]

.Please, I also need help. If you can help me with some information. I recently bought a navigation similar to yours. The difference is that mine connects to car CAN, not to comfort. And it doesn't have that plug between the cable from the radio and navigation. I bought it second hand and the person who sold it didn't give me that navigation module without a manual. Does it influence something? Can it be bought separately? I have an Audi A4B8, 2.0 TDI, 2009. The car was equipped with a Chlous radio, which I changed to a concert+ display. I specify that I have no navigation and no AUX plugs or AMI module. I didn't even activate the AUX function from the secret menu. After installation, I noticed that it only reads the comfort part. The navigation starts and stops when I remove the key, but it drains my battery. The radio starts, the stations are heard, I change them blindly, but it does not show me the stations or the other functions shown by the original display. When I let it show me those original functions, it connects, but it only shows me some lines. I tried all the codes, but I didn't succeed.... The rest works fine, what about navigation. Either the navigation is faulty or something additional is needed in the car. Thank you very much for understanding.
