Fitting avic x1r to a4 b5 help

[frankiejr]

I have just recently changed cars from a fiat stilo to an audi a4 and am wanting to swap my avic x1r over.

It was a nightmare getting it out the stilo as it was fitted by an ice specialist. now i have everything out i realise reinstalling it isnt going to be easy going

Anyone fitted one already? i really thought it would be plug and play...

ok in the wires i removed i have found a can bus interface. i am guessing i no longer require that as i dont think the b5 has can bus? can anyone confirm this?

me again.

i have just taken the sony stereo out the a4 to have a look and the wiring and found this:



anyone have a wiring guide to show what all of these are for? I can see the rear speaker wires arent in the iso set up so will need to do something about that.

connect the rear spearkers to the sub or rear output on the stereo

 

[frankiejr]

connect the rear spearkers to the sub or rear output on the stereo

thats how it was set up on the sony h/u. do you know what all the other wires are for though? im confused as to why there are so many?

The black ISO connector is power (red/blue is perm live, brown is earth and there will be an ignition on live 3rd pin along from earth).
The brown ISO is just front speakers
The multi coloured connector is CD changer/DIS/rear pre-outs
Blue is CD changer
Green is DIS - display on dash
Yellow is rear pre-outs to feed the feeble rear amp bolted to the left deck speaker

You really don't need to use the pre-out part, just wire the rears directly to the new HU as the 2x20w rear amp will be totally overpowered by the fronts running off the HU.
The big red connector with 2 wires on it is illumination and earth, so that the stock HU dims with the dash lights.
Here's the original schematic for the stock radio:

B5's aren't CANBUS so you can ditch the emulator.

Thanks for your reply.

so the block for illumination i can ignore.

what is the brown wire for that goes to the black connector?

the cd changer / dis etc like you say i can ignore.

all seems good. will post up pics when i have this sorted and in.

do you know where i can get the speed pulse?
