Well you could but it wouldn't be easy. There was an adapter for certain
Sony Clie (Palm-based PDAs) to UniLink but it was mainly for GPS IIRC. It
was only compatible with 2002+ UniLink heads I believe and what it would do
was mute the stereo and replace the audio with prompts from the GPS-equipped
Clie. This adapter was quite rare and relatively expensive, plus you had to
have a compatible Clie and GPS unit and software for it to all work.
What you could do with the XA-300 would be to route cell-phone audio to one
of the inputs and then manually switch to that input when a call comes in.
You'd need to have a phone with a micro-jack headset port (most phones have
this but some have a proprietary connection for wired headsets), which you
could easily extract the earpeice audio from using widely-available adapters
and route the [mono] audio to the XA-300. You could also hook up a mono mic
via the same connection.
The cell mute wire that seems to still be on a lot of Sony HUs is pretty
useless. Not because it doesn't work--it does, that wire will instantly
activate the attenuation feature on the HU--but because there aren't any
phones/cradles these days that support ring-output to actually activate that
feature. It's ashame too, I've also always wanted to use that feature but
the phone manufacturers just don't make such equipment and I've seen little
aftermarket gear that can do it either. But there isn't really a way to
combine the use of the cell mute wire and automatic input of cellphone
audio--it doesn't work like that unfortunately.
There are some small novelty items I've seen that can detect certain cell
phone frequency activity (like pens that can light up when a cell phone
rings for example) that given enough work you could probably somehow build a
circuit to activate that mute wire. I know Pioneer used to have an adapter
like that, which would detect CDMA activity (and perhaps GSM and TDMA as
well, I can't remember) and would activate the same wire on many Pio HUs. I
don't know if they still make it but it's a thought...
