Refer to http://www.scangauge.com -- here are the basics:
It's a small box that fits nicely on half of the shelf created when the door below the radio is dropped, though for me that's a temporary mounting. Package includes mounting velcro, cable permanently affixed to the box ending in the OBD-2 connector, and a 24-page manual about 5"x6".
This gadget can be used on any OBD-2 car including CAN cars, and especially the '04 Prius. My son opened the box and got it installed and functional as we were driving...
When you first plug it in and hit the HOME button, the panel illuminates and you see four options: SCAN/TRIP/GAUGE/MORE. MORE leads to setup functions, including engine displacement, HYBRID setting, etc. SCAN provides error codes, if any. It also supports backlight and contrast control, provides compensation for changes in tire size,
TRIP functions go FAR beyond the Prius capability, including average speed, ET, fuel remaining, max coolant temp, max speed, and more. GAUGE permits each of four positions to be cycled through the following:
FUEL SYSTEM LOOP STATUS
INTAKE AIR TEMP
WATER TEMP
FUEL PRESSURE
GALLONS PER HOUR
ENGINE LOADING
MPG
MPH
MANIFOLD PRESSURE
RPM
THROTTLE POSITION SENSOR
BATTERY VOLTAGE
You can set up the four simultaneous readouts as you see fit, and your preferences are recorded in flash memory. Thereafter, the unit always starts with your last selection. I picked WATER TEMP, MAP, RPM, VOLTAGE but will experiment.
There's obviously no book of trouble codes for every car on the road, but many cars are covered on the net (couldn't find our Prius, regrettably).
Overall, I am very impressed. Price was $130 incl shipping from AZ, and I think this gadget pretty much eliminates the need for experimenting and building, except for fun. The electronics in the box occupy so little space that I plan to install everything behind the panel, in front of the steering wheel.
