I got my a3 8p last week and it got dock in the glove box instead of the 6 cd changer the only thing Is when I plug me iphone4 in then start driving it wobbly out of the plug and stop playing. Iv got a little bag of plastic bits but none of them seem to fit and make the phone not wobbly can anyone help me with this. Is there something I can buy from audi to stop this.
