Subaru owners are a loyal, safety-conscious community — and Subaru’s EyeSight driver-assistance suite already provides lane-keeping and adaptive cruise, but no head-up display. An aftermarket HUD brings the missing piece to every Subaru in the lineup.
OBD2 compatibility across Subaru models
All US Subaru models since 1996 have a standard OBD2 port under the driver-side dashboard, to the left of the steering column. OBD2 HUDs work fully on all models — Outback, Forester, Crosstrek, Impreza, Legacy, WRX, and BRZ. Subaru’s proprietary data (EyeSight status, AWD torque split) requires Subaru-specific diagnostic tools, but standard parameters (speed, RPM, coolant, voltage) are accessible to any OBD2 HUD.
Best for Subaru Outback and Forester: OBD2 Pro
The OBD2 Pro suits the adventure-oriented Outback and Forester well. Monitoring coolant temperature on a loaded roof-rack trip through mountain passes, or catching a fault code before a camping weekend, adds real-world value to these vehicles. GPS speed verification is also helpful on remote roads where posted limits change frequently.
Best for Subaru WRX: OBD2 Pro for RPM monitoring
WRX drivers particularly benefit from RPM visibility. The EJ25 and FA20 turbocharged engines reward smooth, informed throttle management, and having RPM in your peripheral vision while driving enthusiastically is a genuine advantage. The OBD2 Pro displays RPM alongside speed and coolant temperature — the three gauges a WRX driver watches most.
Best for EyeSight Subarus: GPS Lite (no camera interference)
Subaru recommends against placing items near the EyeSight stereo cameras, which are mounted at the top of the windshield behind the rear-view mirror. A GPS HUD mounted low on the dash, well away from the camera area, creates no interference. For peace of mind on EyeSight-equipped cars, the GPS Lite is the cleanest choice.

Frequently asked questions
Does Subaru EyeSight interfere with a head-up display?
EyeSight cameras are at the top of the windshield behind the rear-view mirror. A HUD mounted low on the dash is well away from the camera zone and does not interfere. Avoid placing any accessories on or near the top-centre windshield area where EyeSight cameras are mounted.
What is the best HUD for a Subaru WRX?
The OBD2 Pro, for its RPM display alongside speed and coolant temperature. WRX drivers benefit most from these three data points in their peripheral vision during performance driving. The OBD2 port on WRX is standard and fully compatible.
Do Subaru Outback crossovers work with OBD2 HUDs?
Yes. All Subaru Outbacks from 1996 onward use a standard OBD2 port. The OBD2 Pro is fully compatible with all Outback generations and reads speed, RPM, coolant temperature, voltage and pending fault codes.
Does Subaru have a heads-up display?
No Subaru model — Outback, Forester, Crosstrek, Impreza, Legacy, WRX or Ascent — currently offers a factory heads-up display. Subaru’s EyeSight suite provides driver assistance but no HUD, so an aftermarket OBD2 or GPS heads-up display is the way to add one to any Subaru.
What is the best heads-up display for a Subaru Forester?
The Subaru Forester works with any standard OBD2 HUD. The OBD2 Pro is the top pick for a Forester heads-up display — it reads speed, RPM and coolant temperature from the Forester’s OBD2 port, which is useful on loaded roof-rack trips through mountain passes.
