I'm thinking about trying to install a corvette heads up display in my bonneville.
I have been looking at them on the net and they are much nicer then the bonne huds.They have both speed and tach with different views that you can switch.
Here is a video of it YouTube - Corvette Z06 Heads Up Display (HUD)
I have looked at the wiring and the seem to have basically the same connections(But a different harness and an extra connector for the page selector switch which would be easy to add) and also class 2 compatible for the 05 and earlier
What I'm not sure about is if the different angle or even the distance of the dash to the windshield would effect the image?
