[CV60VE]

hey guys
I own a VT wagon Executive
And i was just wondering is there an electric speedo installed on theses things if so how do I get it to work.
I have read through my manuals but found nothing the reason im asking is my mate has a VS and his brother a VR wagon both older models than my car and they have it so I though why should mine not

Thanks in advance for answers
cheers

Yes they do,its commonly called police mode. You have two options,go to holden & ask them to set it with a tech2 to read a digital speed reading. Or the other option is a temp fix & will have to be re-set everytime you start the car. before you turn the ignition on hold the mode & up buttons then turn the ignition on to start the car,after the car has started(a few seconds)stop holding these buttons. when you turn off the car it will resort to the normal settings.
vr-vs commodore can have it done permenently by doing similar but not for vt's as far as i am aware
