I've looked at that site but they don't seem to have anything for either Alfa Romeo or Blaupunkt. Thanks anyway !

I did find something on the PIE site however. They didn't have anything for Alfa Romeo too, but they did have an Aux-in adapter for Blaupunkt HU's. (which the Alfa's stock radio is). I've ordered it and am now very curious to see if it'll work. I sure hope it will !
