I just went out and tried this, and it didn't work in my 06 premium with mycolor. I wish I could have MPH displayed on that screen at all times.

Can't wait to try this, our speedo is tough to read accurately. Wish Vehicle Speed was a standard option of the display settings.

I tried this last night and it worked.

There was a post a LONG time ago here about it. I tried it then on my "12 GT Brembo Base model and it worked. I drove around on it a little.

Tried it when I got home, worked like a charm on my 2010 GT Premium. Great post Lawrencecar1, just wish I could get the speed to stay permanently. Some of the other items like specific voltage are nice for diagnosis as well.
