I use the Valeo GPS HUD now for several months - at my speedometer I look now no longer. The HUD can be installed, who likes to tinker or so someone in the family is very simple and straightforward may have the power cord disappear in vents or under a cover. The display can be in most cases without adhesive film, reading only in strong sunlight it is a bit too pale. With adhesive film, it would then also be no problems, but I have left them off. Due to the GPS receiver, it takes a while until the device has captured the speed and displays, especially if you start from a parking garage. That is also the only, but systemic, gripe: The speed measurement is somewhat delayed.
Conclusion: Each can live with the latter restriction, I can recommend this HUD with a clear conscience.
