I've been thinking for a long time about what kind of LCD I wanted to put in my WRX's dash.
I wanted a LCD that used LVDS so I could hook it up directly to the motherboard.. and not have to use a controller board to hook it up via a VGA port.
An 8" widescreen LCD would fit the double-din opening perfectly, except that they're hard as hell to obtain in single-quantities, basically making them unavailable.
A 7" widescreen LCD would be slightly smaller, and is easily available, but not in LVDS.. and the 800x480 problem is one I'd rather avoid.
An 8.4" 4:3 LCD would fit the double-din width perfectly, but is about 2cm too tall.
So instead, I've been looking at an 8.4" 4:3 800x600 LVDS LCD panel from a local supplier, shown and listed here:
Panel layout w/touchscreen:
I created a mockup LCD panel out of foamboard that's exactly the size of the actual LCD panel, and decided the panel will fit, although I'll have to do some cutting.
lcd template.jpg shows the foamboard mockup, with lines drawn on it to show where the actual display area would be.
mockup1 and mockup2 show the foamboard LCD taped to the radio bezel - you can see the drawn lines match up with the width of the bezel opening.
mockup3 and mockup4 show the LCD and bezel in place on the dash.
You can see that the LCD will fit.. but I'd have to lose the cup holder in the upper right, cut away the plastic in the upper left, and reshape the bezel entirely.
I can live without the cup holder, and those plastic parts are replaceable, so cutting it up wouldn't really be a problem for me.
I'm thinking that the computer itself would go above the vents, in one of those gauge pod housings, so the LCD would be close enough to the motherboard for LVDS to work (~12").
