Once attached it does not move (it can not because it is bonded) so if you park in the city, there is shown behind the windscreen in full sun and in the sight of all, suddenly you can not change vehicle !!! Since I have no desire to make me force a door for that, I glued two magnets on my dashboard and a metal plate at the base of the HUD to be able to remove it and put it in shelter looks. Otherwise it's nice ...
