here is some links that might be of interest for the car PC idea:

That sounds cool Matt! And, yes, you are exactly correct - I need to
replicate the "Master" Unilink functions, as if I install a Car-PC, the C90
would no longer be part of my system (just the Car-PC, and the XDP-4k
connected via TOSLINK). The XDP-4k is 100% useless w/o a Unilink master,
and once I get a 7" LCD Touch-Screen Display in my dash, the C-90 MUST go!!!
The beauty of this config is: Full 7" COLOR touch-screen display that you
can actually READ (lol), DVD-Navigation (I still get lost in my hometown
of
31 years!), as much music data as you can possibly think of (even in WAVE
format if desired - 400Gig, 1TB, or more, easy as pie), AND still
retain 100% of the XDP-4K's SQ (the C90 really has nothing to do with the
sound if an XDP-4k is used).
I was aware of the XDP's latency/delay issues, and DVD Movies would be few
and far-between (I usually DRIVE when I'm in my Truck). I might rig-up a
seperate analog connection from the Car-PC to a dedicated "DVD-Movie"
speaker set somewhere in my truck (bypass the XDP alltogether for
DVD-Movies) - but I doubt I'd watch DVD's more than once a year -
seriously... I'm not concerned about that in the least for now.
I am VERY serious about paying for time and resources to make this
PC-to-Unilink control happen, but I don't want it to turn into a $500
project on my dime. I am also slightly worried about a Car PC's Toslink
output. The Toslink would most certainly be a 24 bit SPDIF signal. Maybe
using a software Dithering plug-in to bring it back to 16-Bits would do the
trick - but the Optical Transmitter might still be sending 24 bit
Data (16bit Data with 8 Bits of "0" placeholders?). I guess I could scrouge
up an old 16bit Toslink soundcard, and use a PCI-Riser to install it into
the Car-PC - but then I can expect Driver issues and such (only really old
cards would be strictly 16 bit). I'll do some experimenting with a "24-bit
Capable" SPDIF soundcard, and see if dithering to 16-bits in Software still
results in a 24-bit output data stream...
I toally spaced: Actually, I believe I hooked up my Roland VS-2480
hard-disk recorder to my XDP-4000k a long long time ago (the C-90 was still
connected, I just plugged my Roland into the XDP's Head-Unit Toslink
input). I know for a fact it outputs 24-Bit SPDIF DATA, and I believe it
worked just fine (I'm assuming the XDP simply truncated to 16 bits - that
is
OK for Car use IMO. We are not hearing those lovely Reverb Tails while
driving 95 MPH down the freeway lol ). I'll double-check this next time
I'm
at our rehearsal room (Tues or Wed).
More pondering and experimenting to come :-)
A big THANKS for any more input.
