Hello all! Newbie here. my question is i have a 2007 audi a4 w/ symphony headunit. I have a D3 that i am in the process of installing. I just purchased the sir-pnr2 siruis pioneer sat tuner and was wondering if i have to use the supplied sat radio antenna or can i just plug in the pre-wired antenna that comes w/ the car from the factory? is the factory sat radio antenna plug located behind the factory headunit (left unplugged)? would i be able to just plug in the factory sat radio antenna into the sir-pnr2 antenna jack? please any and all info will be helpful. TIA!
