I have the older version. It can be mounted anywhere you wish to mount it via velcro strips. I use it to monitor my gas mileage (Miles to go, miles traveled, gas used, gas remaining, time traveled, time left on tank, etc.). I have started monitoring the TPS sensor to improve my mileage (currently at 23MPG for the tank). It has a lot of funtions that I don't even use. I can see my Ignition Timing change as my foot gets heavier and lighter. The website is pretty self explanatory. I now wonder if they have some sort of a exchange program so I can get the newer one.
Here's a few pics of mine.
