*Please plug into OBD2 port of car first before you stick it on and ensure you can read data as some cars run protocols that we cannot confirm.

*Note that even on some OBD2 compliant vehicles, this device may be incompatible and some gauges/readings may not be available as well. Please get in touch with us first to confirm. Note that for oil temperature and turbo pressure, this device relies on information from your ECU to display this data (and the ECU relies on sensors to measure this data). If your vehicle has no sensor for oil temperature or turbo pressure, there will be no reading and this does not automatically constitute a ‘faulty’ product. Remember that NO sensor means NO data/readings. 

*Returns and refunds due to product incompatibility (without or against OBD2 Australia advise) will be subject to our Refund Policy and Terms & Conditions.

*A lag/delay of 0.5sec – 2sec on live data readings should be expected on some vehicles.

*Not for use on any Hybrid vehicle.

*Not compatible with Subaru vehicles.

Great device for a vehicle that does not have a digital speedo. Easy to install. Mounted above right of dash well within line of sight. Way better than those GPS speedo apps for smart phones.

  1. She’s a solid device, sticks very well to my dash and the cable is long enough to fit basically anywhere I’d like to put it. A great and vibrant display in both day time (where I use it most) and night.

    Rev lag is there but speed is basically instant.

    Love the multiple themes and the settings UI works pretty well.

    Generally a fantastic addition to my car. I no longer need Torque Pro to show my speed digitally thank God!

  2. Works well but a bit pricey

  3. Great little gauge. The team at OBD2 were extremely helpful. We needed an extra speedo to complete a driver’s test in our own car (as the main speedo isn’t visible from the passenger seat). ODB2 helped out with the required letter for VicRoads about the accuracy of the gauge. Responsive and rock solid measurements. Very happy.

  4. Great little gauge, works brilliantly. Fantastic customer service from OBD2 Australia!

  5. Great product
