Need advice on new CarPC setup
Hi everyone. I'm a newbie to the CarPC community but am about to take the plunge into building my own car computer. I have done quite a bit of research and wanted to see if some of the experts here could offer suggestions on my proposed setup. First of all, here are some of the constraints I am working under:
1) The car is a 2006 Jeep Liberty. As such, the radio is a single DIN unit. There also doesn't seem to me much room next to the existing stereo, but I haven't taken it all apart yet.
2) I want to use the car's existing speakers (for the time being).
Here is the hardware I'm looking at:
1) First and foremost is the touchscreen. I don't have experience with the whole bondo / fiberglass thing for making a new bezel, so I think that the Xenarc MDT-X7000 would be a good choice for me. I have read all the complaints, but I haven't found anything else that even comes close to matching it in a single DIN unit. If there are other options out there, it would give me some options. This would also have the side benefit of having a built-in amplifier, so I wouldn't have to install a separate amp.
2) Second is the computer itself. I already have a Jetway 9F2-KHDE mini-ITX with a 2.0GHz Core 2 Duo. This is already up and running just fine. I also already have a 60GB 2.5" SATA HD.
3) Next is the case and power supply. There are many conflicting opinions on power supplies, but it seems that the Opus 70 gets good reviews and would take care of the case and power supply all in one. It's not clear exactly how this hooks into the car battery, but I'm planning to connect a fused distribution block to the existing car stereo power and then connect that to both the Xenarc unit and the Opus 70. This should work, right?
4) Software. Looks like streetdeck is the one with all the features I'm looking for. Which is basically mp3/radio/video/navigation. Unfortunately you can't buy it right now, but hopefully that is changing soon.
5) I would also need a GPS unit and AM/FM tuner for the PC. I have not researched these, but suggestions are welcome.
I have looked for a single DIN "all-in-one" computer with a retractable touchscreen like the MDT-X7000, but the ones I've found appear to be very poor quality. Is there any such beast out there (single DIN, decent computer, touchscreen)?
There are things that I don't yet understand. I am not sure how the PC will know that the ignition has been turned off. I know there is an ignition wire to the stock stereo and that this somehow gets connected to the Opus 70 which then sends the signals to the motherboard, but the exact mechanism is unclear. Also, when the car is turned off, the PC will hibernate for a while and then shut down? How does this happen?
That's it for right now. If anyone can help clear things up for me, that would be greatly appreciated. Thanks and I will post updates as things move along.
