Here's my Cardroid in my 04 SE Wagon... turned out all right. Still dealing with the battery issues with the temperatures here, but I've got 4.2A pumping into it. Runs off my phone's wifi (which, thanks to CyanogenMod, starts automatically when it connects to the car's bluetooth headset). I'm still on Verizon's Unlimited plan (Yay!) so data isn't a concern for me. Dell Venue 7 w/x86 processor. TBH the only reason I chose this over most other tablets is it has a sd slot. External GPS (soldered to main board, along with a secondary wifi antenna) fixes to 14+ satellites within 3 seconds. All of it is connected to the aux in of my JVC which I placed in the glove box. A simple USB ir repeater placed in the driver center air duct lets me continue to control the radio when the glovebox is closed too. Also routed a button to the dash that let's me turn on/off the screen and power it down should I need to. (not shown). I must say, I love having pandora, youtube, netflix, etc in the car, and so does my girlfriend on long trips.
Oh and having TORQUE, BEST THING EVER! Got a OBDLINK MX Bluetooth plugged in at all times. Managed to post a 10.46s 0-60. Not bad considering it's 11 years old and weighs 3000lbs with me and my tools in it.
I know my moulding (which is bondo base for strength, and then wood putty ontop of it because that's easier to form) isn't the best, but you really don't notice it. Plus, I did all of this during the recent fridged month while attending Purdue. So school comes first, car close second, followed by homework and studying

After that, a bit of plastidip to try to get a uniform texture/color on the bezel. I'm hoping in my next install to have the bezel done professionally.
