Hi guys,not sure whether this topic has been discussed before. Sorry if it has been.May i know what is a Parktronic / PDC / Park Assist ? Is the 3 same ? in what model / year of beemers can i find these features on ?I have tried googling and utube'ing but most result came out is for Mercedes and BMW 7 series.I am looking for a E39 or maybe E46..hopefully this 2 models have it..From what i understand, it is a reverse and front sensor that produce beeping sound when getting too close to an object. no ? no pun intended :smokin:
