Audi A3 2004 Aftermarket Headunit fitting cables help!?

[FINEST_A3]

Iv bought my self a Alpine Popout screen, D106r. But I'm not to sure which wiring harness I would need, been given so many different types do wondering if any of you could help. Iv got a non-Bose 2004 Audi A3with a concert cd player currently in there, I believe it's already got a sub and amp in the back.
Also would it be hard to do the ignition feed? Or is the canbus worth it? Also since its a screen how would I connect it to the handbrake?
Cheers

You need the ISO RCA input adapter
Just earth the handbrake wire

Sorry bit new too this stuff, where does the red and black cables connect to?
Really appreciate your help, thanks!

 

[FINEST_A3]

And the pc9-404 says its for Bose? Would this still fit mine?

 

[AndyMac]

The Bose one works for both, but the 404 is actually for non Bose (only one set of RCA's)

Ok thank you for ur help, just ordered the cable!

I've connected the 404 but Im not getting any power to the screen? I've connected the blue and white to the blue remote cable from the back of the stereo but nothing happens?

As there is no ignition feed on the Audi loom, you need to either wire one in from the fusebox or pair the red and yellow wires together and turn the HU on/off manually
