Moin Community, I would like to upgrade a radio with touchscreen for my B6. I have looked at the internet and wanted to ask you if you have any experience with the models, or if you could tell me what I have to pay attention to when buying and installing them. Here are the selected models:http://www.amazon.de/…/ref=sr_1_5?…http://www.amazon.de/…/ref=pd_sim_sbs_23_1?…http://www.amazon.de/…/ref=pd_sim_sbs_23_2?… In particular, I would like to know if the connection to the car works without problems (sound system etc.) and whether you need any adapters or similar. I am already happy about your answers With friendly greeting and nice evening still
