(The image isn't actually this fuzzy, it's just my camera.)
The display I used is a VFD (Vacuum Fluorescent Display) from
matrixorbital.com. I got one with a 2x20 display and 7 buttons. It was
designed to fit in a 5.25" PC bay, so it fits perfectly in the CD
compartment in my dash.
It has a serial port interface, which makes it very simple to program, just initialize it and send some strings across.
I chose the VFD over the cheaper LCDs, because the LCDs are only rated to 122°F, and I live in Phoenix, where my car hits 140°F in the summer.
