I know that most of you probably feel that Acoustic Parking Assist is a silly feature, but the gadget head in me can help but be interested in it.

I am buying an A6, and have found a perfectly configured A6 2.7T except for the lack of the Acoustic Parking Option. Are their any good aftermarket acoustic parking systems out there that someone would recommend? If so I can buy the Audi sans parking, get my car quickly and be happy :-)

Thanks,

Jason
