Hello, I had another navi or infotainment installed. (From Lithuania) After I noticed that it did not fit my car I expanded it and installed my old one. After that the sign recognition shows me only a white 4 corner. And does not recognize the signs anymore. By the way, my navi doesn’t work and my Bluetooth. Can it do with it? But before that it does not work it can’t be because of it. Buy me now a German infotaiment yard This is fixed! Do you have any tips on what it can still be? Thank you very much
