If this is what you are after, the install is easy, it's the wiring that can get to be a headache...All you have to do to do this is remove the dash trim (wood, metal, whatever you have) release the screws that hold the radio and IHKA, remove the sunglass holder and replace with the IHKA. To do a HUD is a little more involved, it takes special glass in the windshield (without the special glass the image is distorted) mirrors that have to be adjusted to reflect the projected image onto the glass, and of course a projector it would be quite an aftermarket task to say the least.
