A road trip is when a head-up display earns its price back in a single day. Navigation
directions, your speed, and fuel economy — all visible without dropping your eyes from the highway
ahead. This page covers the best HUD tier for long-distance driving.
that mirrors your phone’s turn-by-turn directions — the RoadView Max is built for exactly this.
RoadView Max — Built for the Open Road (~$249)
The RoadView Max mirrors turn-by-turn navigation from your phone onto the windshield — so the
next junction, speed, and vehicle data share your line of sight. High-brightness optics stay
readable even in direct afternoon sun on open interstates.
OBD2 Pro — For Fuel-Conscious Long Haulers (~$69)
If you already know the route and want to focus on fuel economy, the OBD2 Pro is the pick.
Live instantaneous fuel economy on the windshield helps you find that 60–65 mph cruise sweet spot
where petrol engines are most efficient. Estimate your savings with the Fuel Savings Calculator.
Frequently Asked Questions
Will a HUD work in a rental car?
The GPS Lite works in any rental — it plugs into USB or a 12V adapter and sits on the dash
without permanent installation. The OBD2 Pro/RoadView Max connect via OBD2 which technically
works in rentals, but check your rental agreement first.
Does phone navigation drain the battery on a long trip?
Route the phone charger through the same 12V adapter as the HUD, or use a second USB port.
Most modern cars have two USB-A ports in the center console.
How bright does the display need to be for daytime highway driving?
Look for at least 10,000 nit-equivalent brightness or an “auto-brightness” sensor.
The RoadView Max is specifically selected for daylight readability; the OBD2 Pro handles most
driving conditions with its auto-brightness setting.
