The face plate of the radio is shaped specifically to fit the Audi model's
center console, so you will probably need to do some custom work to
make it install right in a non-Audi car.

The CAN bus is used for communication with the instrument cluster.
On the Audi, the radio mode/frequency/name etc can be displayed there,
and on the Symphony II it is likely used also for speed information (for
speed adjusted volume), because there is no separate speedometer signal
connection.  These are probably inconsequential to you, but there
is one feature that may be a problem...  The Symphony II's security
lockout feature is coded to match the car.  I am not sure, but even if
you have the unlock code, it may not be sufficient to wake it up.  You
may need to re-program the radio via the diagnostic port, using the
VAG scan tool.  However, when installed in a non-Audi, you lose *that*
connectivity (that's what the K-line is used for).  The new security
feature of this radio is that even if it loses battery power, you don't
have to enter the security code to unlock it if it is still connected
to the same car after the power is reconnected.

Assuming you get the radio to wake up and get past the security lockout,
and have all the needed wiring done, these should be no problem.
Note that Audis that come with this radio have an antenna amplifier,
and a non-amplified antenna may not provide sufficient reception.

> Display dimming with Headlights/dashboard dimmer

The radio display does not dim with the headlight switch.  It has a
light sensor that automatically dims itself in a gradual manner
depending on ambient lighting conditions.  The buttons' backlighting
is probably something you lose without having the CAN bus connectivity
to the instrument cluster, since there is apparently no separate dimmer
signal connection.

Yep.  You're not going to get that if you don't have compatible
perpheral systems in the car.

I'll include the connection description for the older Delta CC and the
Concert I/Symphony I radios below.  The Symphony II is only slightly
different than the Symphony I, so hopefully that will help you get
things wired up correctly.

Yes, but it's not a simply aux input.  There is a external CD changer
input, and you have to hook up an active adapter to fool the radio into
thinking that it's talking to a CD changer before it will let you switch
to it.  Blitzsafe AudiAUXInputAdapter and Soundate SDS1 are both usable:
