Yea, i think i have one laying around. Its cheap enough though that its worth buying one to save the time i'd spend finding the one i have. Its a haystack of cables etc in my office. And thanks, I'm glad there are people interested!

7" Touchscreen Assembly
- This thing is really nice cuz the screen is already assembled in the vehicle mounting frame with sensors and ports repositioned to the front in case you want to use them
Automatic Startup/Shutdown Power Controller
- Pretty sure this is crucial for an in-dash installation if you want to avoid the need for external switches.
- For that factory-flush fit. This seller appears to still have a bunch. But either way, you have the Scosche model number on that listing in case you need to find it somewhere else.
If I come across anything else I need to buy for this install (other than generic things, memory cards etc) I'll be sure to list it.
As far as I know, you have to boot from the SD card but can modify the kernel to use a USB drive as the root file system. Here is a link to an SD card socket mounted such that you can make connections to it and potentially either extend the existing one or perhaps add another: http://www.byvac.com/bv3/index.php?rout ... uct_id=122
There are some other handy bits and bobs there too.

Thanks guys. I'm comfortable having the SD card be the only form of storage right now, especially since I'm relocating the SD slot right next to the screen bezel on the dash.
I love to hear peoples' ideas though, so keep em coming! =] And hopefully I'll give you guys some ideas as well.
So, on to the updates from this morning.
Here's a picture of the power controller:
And here's the quickie schematic I drew up for the power connections: full size image
(i'm still operating under the assumption that there was an external factory amp for my radio.. i should probably figure that out soon!)
One thing I thought about this morning is a resume capability. Using the auto power controller, I won't have to worry about turning on the computer, it will turn on with the car. However, it will also turn off with the car. I can set a delay, but does anyone know if there's a way to save a state in OpenELEC or any other distro so that when power is restored it will resume? Another option would be to put only the screen on the power circuit and give the raspi constant power.. but I would have to make sure the standby current draw is extremely low. Anyone have specs on that?
