I'm doing an AVIC-D3 install in an '08 A4. I've got the Symphony II+ which has a different wiring harness than the Symphony. I've heard its the same as the RNS-E. Any ideas as to where I can get a harness and an antenna adapter (antenna adapter is different too (not standard euro adapter, it's got 2 wires into a square plastic plug))). See below for the sticker on the radio.
