Is it time to deploy a head-up display for a road trip?

Head-up display (HUD) devices for cars typically project navigation information, travel speed and other useful pieces of information to the windshield so that the display doesn’t block driver’s view to the road ahead. It is easy to install a head-up display to an old and trusty road trip vehicle as well, but is the device worth the investment?

The prices range from 20 to 500 dollars because there are two types of products in the market. Products with low price tags are simple devices that reflect your smartphone display onto the windshield, whereas high-end products are connected both to the car’s information system and to your smartphone for processing and displaying a mix of data onto the windshield, for playing music and for managing phone calls.

An example of a high-end head-up display product is Navdy. A Bloomberg journalist made a road trip using the Navdy and concluded that it was very difficult to return to the old way of navigating (using a smartphone) after the trip.
