First of all, what a great resource on the internet.
Now, on to the main event.
I've had this crazy idea about installing a mac into my car for a long time (much like the rest of you). Now I find this site and realize its a reality (after all, many of you are already doing this in such great execution).
Well now I want in.
I own a 1998 Honda Civic EX and am getting ready to make the nessecary purchases to start this labor of love. I'm going to make plenty of mistakes and realizations and I plan to learn a lot so that in a little more than a year I can transport the new Mac Mini and VGA screen to a new Honda Element and do the job even better.
Anyway - here is the known hardware I'm going to purchase for my project.
1x Mac Mini 1.66 GHZ, 512mb ram, 160gb hard drive.
1x Carnetix CNX-P2140 185W Dual Output Intelligent DC-DC Regulator (to power said Mac Mini).
1x MacPac Power Cable Kit (for obvious reasons).
So here are my questions:
1. What kind of screen would be best to view all this snazzy stuff? And how do I power said screen? Would touch screen be best? Or using Front Row, could I get by with no touch, an apple remote, and a wireless KB and mouse for a co-pilot (or when parked?)?
2. How can I add other accessories requiring power after I install the Mac Mini and the screen? I was thinking of navigation just because I am aware that nav is a little hard to come by on Macs.
3. How could I get XM or Sirius Radio working with the Mac? And in anyones honest opinion, would it be better to operate the satellite radio through OS X software or just install a separate satellite radio in the open space above my cup holder?
Everything else I like to think I have a handle on, but please throw anything my way you think would be helpful.
Oh and I hate to do this:

But once I get this fancy Carnetix PSU, how do I wire it into my cars power system?
Thanks in advance.
