I have a factory radio Chorus 2+. I inserted RNS 193G. I replaced the amplifiers in the rear window, added cables, encoded the cangateway 37-Navigation and a few others in long coding and adaptation. The VCDS does not show any errors, super blows, except for the radio and Gala. The radio works as if the amplifier did not work. I checked everything in the measuring block. In engineering mode the speed shows, gala-5 does not work. I replaced three units and all had the same defects. I think something disturbs the work of the radio. I wanted to ask what to do, maybe I still need to encode something.
