hello my armada family, sorry its been a long time since I got on here sold the truck, any how the truck is still the same only difference is its has 28 inch wheels now and a big system. The problem it has right now is the speedo, in park it stays at 20 mph when you drive its 20 mph over.

First try this


With ign OFF press and hold the reset button
continue to hold the reset button while turning the key to ON
When you see the "test" screen on the dash let the reset button go
push reset button till yo uget to a screen where it sweep all the needles.
Usually that will reset the needles.
If that don't work you'll have to manually re-position the needle
NOTE: I have done this with a Titan and soe have done it with the Mada
I'm sure it's the same for QX but not 100%

Where is this reset button you speak off? Sorry for my ignorance, are you refering to trip reset button?
