I recently acquired a 2006 CLS and have considered adding Distronic to it. Someone on the 211 page noted that his system (a little older so may not be the same) originally worked well but as more cars have some type of radar system his Distronic is constantly switch off and thus now is nothing but an annoyance. Can anyone confirm or not if that is the case with the Distronic system on the 2006 CLS? Many thanks for your comments.
