Trailer coupling V70

The last trailer coupling thread from the XC90 makes some optical discomfort rise in me. Is the removable trailer coupling from Volvo on the V70 a similar “good” solution? Have I read somewhere in the forum, the bicycle carrier would rock, due to the removable ball head? What is it like with the cover, does it look really so ugly, does someone have a pic or a link? Who has experience with alternative solutions (other manufacturers)? E***embryo
