i recently have fitted a defi heads up display in my car and it seems to be displaying the wrong speed.
for example.....
speedo will read 80mph
defi heads up display will read 60mph
speed camera gps detector will read 70mph

i was wondering if anyone could tell me if the defi heads up display can be re-calabrated to the correct speed??????????
i belive its around 10-12% out

Sounds like yours isn't set to the correct speed pulse.
You can change it in the setup menu.
