I'm using the UG in a '98 Toyota 4Runner, the gauge should support 33 functions - MPH is one of them obviously and since my UG is not displaying the correct speed (it shows 4mph when I'm going 50mph, etc) this negates several more gauges - avg mph, trip mph, etc. As I said my speedometer works in my 4Runner so there is no bad sensor on my end it has to be a faulty Ultra Gauge.
I wasn't sure how yo get a return/repair ticket, I'll have to search this site avlittle more, thanks for any suggestions...
