Hi, have been lifting my T-Roc 2.0tdi DSG 4M (Sport) for a week now. A really good car! PRonlem what I bought is because I bought the model which was taken by my handler on location. I miss some things I liked to get to rest. Unfortunately my friend has cancelled me at ALL!, what I really didn’t believe. 1. Rearview camera – should not be possible. I liked the original or Kauftec variant on original Discover Media (with Navi pro) anshliesen un dana ch (if possible program) if other solutions are given.. am only open. 2. Activate Highlight Assistant 3. Activate Rain Close 4. Activate Charging Mark Detection 5. Show Climate Blower Stage in AUTO mode Can you please help me? attached also images of camera that are available is thank you
