When it connects it works well. Problem is It connects about 10% time. I have even gone so far as to make sure everything in my truck wirelessly turned off. The iPhone automatically joins the network. When the app is launched it says connection. This product is very very unreliable. I wish Quadzilla would release an update to fix these connection error problems. A lot of money spent for nothing but a neat idea.

Smart POD DOES NOT WORK. Rarely connects with out repeated attempts. Transmission temp shows -10 degrees after sitting in my 30 degree garage all night. It's a very cool idea if it would work right.

so far, the instructions on how to use the software were a not very good. i have been messing with it for a little while, and have most of it figured out. i still dont know how to toggle between the gauge readouts but somehow it changes itself (there are 3 different configurations). when you link it to the truck it only shows the speedometer at first... i am not sure what to hit to bring all of the guages up but eventually after randomly tapping the touch screen all over it came up. it froze about three times and shut itself down twice. it was cutting in and out for about 5 minutes where it would only randomly show real time readings. when you hit the home button it shuts the app down as opposed to leaving it run in the background. I hope they just have some bugs to work on, its a cool concept but i am thinking that it may be more of a hassle than its worth.
