What OBDII stuff does it do? What software are you using?
What is the native resolution on this?
I was using (carpc was pulled a few months ago so I can sell my truck) the open (non-proprietary) elmscan OBDII hardware interface from scantool.net. Because it is non-proprietary, there are other vendors that also make the hardware component.
For software, I was using a modified version of scantool.net. I added the Land Rover proprietary OBDII code descriptions, and spruced up the user interface. With OBDII software you can pull codes, monitor O2 sensors, temperature, etc. There are a variety of different software packages out there that work with the elmscan interface. I believe Palmer makes one that allows you to have fancy "soft" gauges. Mostly though, I just used the OBDII interface to figure out what was wrong with the motor if I threw a code in the field. It allowed me to determine if I had something small wrong, like a bad O2 sensor or something more important that would preclude driving the vehicle.
The Xenarc screen I used had a funky native resolution of something like 800x400, but I was running it at 800x600. It was an older screen though. If I were to build one of these again I'd spend the money to get a sunlight visible screen with a 1024x768 screen resolution. I'm using an EO TufTab right now and it is both sunlight visible an has a higher resolution. It is fantastic.
