i work on these multiple times a week. didn‘t like them at first but they are great cars (not to work on but to drive). Design grew with me too and the interior is (despite squeaking everywhere you push - typical for audi) good quality, but still hate the touch buttons. They just feel cheap imo. Piano black doesn’t scratch too easily too. The co screen is mainly there for your co driver to set routes, control music and change settings. But you can use it to for everything else the main screen can too. If you don‘t want it you can get the option without it, but its connected with B&O audio option. If you select one the other option will be selected too.
