speedo is off
I have a question about the reading on my speedo & DIC on my '09 Z06, it is one MPH off from the HUD.
When setting the cruise control, the DIC display of set speed is the same as the speedo, but the HUD displays 1 MPH slower.
Is this common? Is there a fix? Which one is accurate?

Agree, normal.
The digital readout can be almost 1 MPH off at anytime.
I forget how this one works, but the idea is that for instance, 99.001 MPH might read the same '99' as 99.999 MPH. Whereas the analog gauge might move from 99 to 100 on the dial.
