I initially saw this in Mazda6Club, and the guys are all happy about it. Generally they go for $160 shipped. I was able to find $10 off shipped from one of the dealer. The unit was shipped direct from the manufacturer via Priority Mail in AZ. They shipped on the 13th and arrived on the 14th in Point Roberts.

You can also pick up an extra cable for another car for $18.95 (kind of rip off.. but they have the best price)
As you check out (they take Canadian credit cards!!), apply coupon code YTSG2, and the $10 discount should be reflected. $150 shipped is within US only.
Installing it was painless, and setup was easy. Everyone can do it.

It just connects to the OBDII connector, and reads information from the computer. It displays stuff like temp, pressure, mileage, and other stuff that could be helpful and save gas. It also scans for CEL codes and reset them.

I will re-locate it to the area under the vent on the driver side, caz as you can see, it is blocking the speedo.
