You're doing 100 on the Hume and you still can't tell if the engine's pulling or overheating without looking down. This Jaycar head-up display projects speed, RPM, water temp and battery voltage straight onto your windscreen so your eyes never leave the road. Hit the scroll button to flip between GPS mode (speed, battery voltage, satellite count) and OBD-II mode (speed, engine RPM, water temperature, battery voltage, distance travelled). The glare hood and auto-dimming handle night driving without that blinding white square. GPS mode works in 24V vehicles; OBD-II mode is 12V only. Check your state's road rules on mount position before you fix it up
