Head unit help required

Hi all,

My recently acquired '06 Avant came with a Symphony double DIN CD/Tape player which worked fine but had a 'dead' line on the screen. A mate of mine had a Concert II Double DIN which I believe is from a later A4.

I went to fit it but it appears to have the quad lock connection and a strange double aerial connector as opposed to the ISO wiring and conventional aerial that the car has.

I've searched the forums and found plenty around going quadlock to ISO for aftermarket HU conversions but not the other way.

Can anyone offer any advice? Obviously I'd rather not have to re-wire.

Thanks

Cheers Dave,

Looks like what I'm after, shame it's across the pond though, is quote steep with postage. I found this place:

Buy Car Audio Quad Lock MOST Radio Connector parts

So I may just rewire it with quadlock connectors and get the dual Fakra convertor for the aerial and comms.

...And to think when I bought this car I said to myself I wouldn't fiddle with it!

Steep, are you serious?

Your other issue is the radio antenna system will be different so may experience degraded signal reception.

Yes unfortunately I'm trying to do this on a budget and it looks like I need £20's worth of Aerial adaptor, an ipod interface (>£50) and CD changer so a £50 radio upgrade to allow me to play Mp3 discs soon turns to £200.

The aerial thing seems to be a bit of a minefield, my original HU has a DIN radio aerial and a small (believe top be a Fakra?) aerial which i presume is for bluetooth?

The new HU has a twin Fakra(?) aerial connector only. I've found an adaptor which looks like it is the correct item, but i'm not 100% sure:

I'm thinking the most cost effective and tidiest way might be to just cut the ISO's and re-wire to quadlock spec (will post a guide if i end up doing this).
It's been a nightmare finding info on this as it seems that people tend to go the other way (i.e convert from quadlock loom to ISO aftermarket HU). After a number of hours on the net I'm pretty sure can get the quadlock connector parts for under £20 and I like the idea of a direct fit.

I'm going to look at the wiring this weekend and make sure it's relatvely straight forward before I buy the bits. Any confirmation on the aerial situation would be much appreciated though.

Cheers
