12V switched ignition output
I have a 2001 (new shape) A4 saloon, which I have fitted an aftermarket
head unit into. Unfortunately the wiring loom doesn't seem to provide a
12V switched ignition feed to turn the head unit on (the factory unit I
believe used CAN-bus), with the result that I have to manually shut it
down when I leave the car.
Is there anywhere that I can easily get a 12V switched feed from?
Also this particular head unit takes some time to power up, is there an
alternative location I can take a permanent 12V feed from so it doesn't
turn off when starting the engine? (Preferably without having to run an
extra cable to the battery or anything silly like that...)

Audis and VW's traditionally reverse switched power and permanent on
(yellow and red I believe) in the ISO connectors at the back of the
radios. so you might need an adapter or you might need to reverse
those cables in the connector.

Yup Wolfgang is correct, you do have a switched live, just reverse the
red/yellow had to do it on both my A4's

Careful! This was certainly true on older cars, but the more recent
Audis do, as Glenn suggests, only have a permanent live to the radio and
use CAN bus signals for the power up/down commands. This change
occurred, I believe, when the Concert II/Symphony II range of radios was
introduced. Without referring to the workshop manuals, I wouldn't be
certain as to what to expect on a 2001 B6 A4, but suspect that it will
use CAN bus control.
On my car (a 2003 RS6), I found a row of relays behind the panel below
the steering wheel, with threaded studs to which you can easily add
additional connections. One of these has a switched output, the rest
seem to be permanent live.
