Just an update, I finished installing the carpc tonight (about time), and everything works great so far. Homeseer can start my car in the morning, which boots up the PC automatically, and activate the wireless connection, which then allows my software to update files/music, etc. using FTP. GPS is working as well, the only major issue I have to resolve is the audio (my FM transmitter died).
If I can figure out how to deal with the vacuum properties of my HVAC, I will also install an Ocelot in my car, to control HVAC, Trunk, and other accessories.
Next step: road test, let's see how it survives the potholes created by our snowplows (they are pretty bad).
I put it in the passenger side corner on top of my dash, all the way against the window. It fits nice there, but I would rather have it centered, since the GPS seems to be that sensitive. I have no idea on how to mount this on the roof without drilling holes, so that's about as crazy as I will go when it comes to securing this unit
I was in a hurry , so they aren't that great. I am planning on switching to NetRemote for the front end (assuming I can find the time), and will be using Voice Recognition as well, using a microphone I will be placing right above me in the visor, or in front of the instrument cluster.
I've been driving around for a few days now, no problems when hitting big potholes or railroad tracks, the 3.5" HD is just fine so far. I wired my monitor directly to my powersupply so the 12V is regulated (and more stable). I also installed a nice microphone (have had it laying around for years) behind my steering wheel, and will be implementing voice recognition using Girder.
I also played with my GPS, huge WAF! I also tested the address book today since I was going to a restaurant, but didn't know the street name, so I did a simple search by name, selected it, and it automatically plotted the route. It also automatically updates the route if you take a wrong turn, and uses voice announcements to let you know when you have to take a turn (announces it several miles ahead, and several hundred feet as well). Really cool stuff!
Next step is setting up NetRemote and Girder, and try to get a working interface, but I have some other priorities right now, so that won't be happening for another few weeks.
