Garmin HUD GPSStore: Lemon Tree
Everyone wants to be cool, right? Like Top Gun cool. So it’s hardly surprising that the gadget makers spend so much time trying to fulfill our fantasies by producing stuff which a few years ago would be firmly in the science fiction category.
The Garmin HUD (for Heads Up Display) is one such product. The concept is to deliver an easy interface to their GPS navigation software by beaming it onto your windscreen or a special plastic reflector lens, so you can see what you need to do without squinting down at a small phone screen.
