I recently got an A4 B7 05plate. It comes with factory fitted 7 disc and cassette syphony unit. I have been looking at upgrades like these audi symphony cd radio | eBay or Veyron VNS-A4 OEM-Style Radio/DVD/iPod/Bluetooth/GPS/Nav/USB/SD for Audi A4 B7 | eBay
Really i just want the i-phone to be linked up, preferably by bluetooth but even just the red and white aux cable to audi jack cable. With my current system is there an upgrade available or will i have to upgrade the unit with one of the above?
Any info into this would be greatly appreciated.
