The box arrived with the following parts an instruction card, which does not tell you everything, but with just a little thought you can work out what the parts may be for.
The easiest part is the HUD itself which comes with an ample sized cloth.
In the front of the box there is the stand and ball socket nut. The instruction card shows how this is fitted, but I found the best way was to partially screw the nut into the underside of the HUD unit then clip the half ball mount into this. I must say the tightening of the nut is fiddly, particularly when there is so little clearance under the unit when it is on the dash.
In a separate box, there is a spare reflective mirror a double sided mount sticker and a piece of wide smooth plastic strip, sticky on one side.
The strip to be useful for those who have dashboards that are not very good for sticking small footprint articles to them like the adjustable base of the HUD. My own dashboard is such, that it has a matt crinkle type finish which looks effective, but is terrible for sticking anything to it. The plastic strip is a boon in this case, allowing a large surface error to stick to, with a smooth top to allow the foot print to be stuck down. The double sided mount sticker, could of course be used to give more height clearance under the bracket when it is on a slope.
Not a bad unit, just a few minor gripes, As has been said the reflection onto the screen and the bracket for the top reflective screen could have been made to be raised to at least the thickness of most mobile phones, so that the mirror surface was level with the top of the phone when laid down.
