The windshield pod we mentioned some time back is now in production and on the shelf. We put a couple of PLX DM-100 gauges in a customer car and they turned out great. We were pleased with the Mach V splash screen, but it's the rest of the programmable functions of the gauges that's the cool part. You can choose between about six different data display modes, each of which is customizable by color. (Note that I was still playing around with colors in the second picture, below.) You can also upload custom wallpaper or gauge styles for each gauge.
If you have more sensors than you have gauges, you can change what sensor is displayed on what gauge using the wired remote control. Or you can display four different data channels in text form on one gauge.
The gauges are just about 1" thick, so mounting is really easy. They'll fit in any standard gauge mount (which is what we did), or you can just surface mount them or put them on a simple stand or L-bracket. They come in 52mm and 60mm sizes.
Reconfigurable and programmable gauge displays are the future of gauge technology. Some of the latest cars have gauges like this -- the Lamborghini Reventon is one that I can think of. Recent airplanes have this approach, too, with LCD screens that display the appropriate data at the right time, rather than just fixed gauges that may or may not be useful all the time. As the technology gets less expensive, more and more original-equipment automotive gauge displays will eventually look like this. But for the time being, it's up to us in the aftermarket to lead the way.
