I am currently looking to buy at NAV+ unit for my 2004 A4. The NAV+ unit will be replacing my symphony II stereo with XM Sat. My car has the shark fin antenna. Will I need to install a secondary antenna for the NAV? I like the clean look of the car with the fin, and would hate to muck it up with another antenna. Any recommendations?

Also from reading this forum, it looks like I need to VAG my car to get the NAV working correctly. Can anyone give me some guidence to what codes I should be looking for?

Thanks for your help.
