A factory head-up display is built into the car; an aftermarket HUD is an add-on you fit yourself. Both put data in your sight line — here’s how to choose.
Factory HUD: pros and cons
Factory systems are polished, full-colour and integrated with navigation — but they are expensive, often locked to higher trims, and impossible to add later if your car didn’t come with one.
Aftermarket HUD: pros and cons
An aftermarket HUD display for your car costs a fraction of the factory option, installs in minutes, and works on almost any vehicle. The trade-off is a simpler, smaller readout. For most drivers that’s a great deal.
When aftermarket wins
- Your car has no factory HUD option
- You want speed and engine data without the premium price
- You drive a BMW or Mercedes without the factory upgrade
Browse OBD2 HUDs for engine data or speedometer HUDs for a clean GPS speed readout.
Frequently asked questions
Is an aftermarket HUD as good as a factory HUD?
Factory HUDs are more polished and integrated, but a good aftermarket HUD delivers the core benefit — speed and data in your sight line — for far less money and fits almost any car.
Can I add a head-up display to a car without one?
Yes. An aftermarket OBD2 or GPS HUD plugs in and projects onto the windshield, adding a head-up display to virtually any vehicle.
Does an aftermarket HUD void my warranty?
A plug-in OBD2 HUD makes no permanent changes and is removed by unplugging, so it does not alter the vehicle.
