Fits our Audi A6 Avant, Bj. 2003 like a glove. Our Audi dealers requested for the original part more than 70 Euro, keyword - antenna diversity, etc. We can no distinction (FM receiving) over the original stock (rubber corrodes) recognize. The Navi even worked without antenna, the ancient telephone system we do not use. Installation: There are two threaded M5 and M6 (M6 needs of AUDI) at. Simply screw with the screwdriver (slot on one end of the thread). (Disturbing prevent water intrusion into the thread and possibly corrosion in the original AUDI antenna without contact) Before the thread side something (in the middle) grease. Result: a perfect fit (indistinguishable from the original) and also works that way. The only drawback: Unlike the original part can be the antenna of bad guys relatively simply unscrew - but that's easier to get over with this part as compared to expensive original.
