1st question: can I integrate my Ericsson 788 cell phone into the plug that is located in the center armrest of my A4 1.8 T so that it works in conjuction to the radio?<p>2nd question: Do I void lots of warranties if I have Greedspeed (or any other company) up rate my turbo to give me 250 Hp (I have already chipped it to 190hp +/-).<p>Sorry if this has already been asked but I could not find the answers anywhere

You'll need a plug that goes on the bottom of the phone that adds a headset jack. If you have one these it'll work with my phone kit.<p>David

Which kit would that be?????
