How difficult is the driver and software installation?

The installation is not plug and play and will require basic knowledge and experience with Windows, installing drivers and software. There is a step by step installation guide.


Note that OBD2 Australia will not be held liable for any damage this cable and software may cause to your computer or your vehicle. As you are dealing with third-party, free, outdated and unsupported software, support will only be provided for the hardware (the cable). Installation and usage of this free software is at your own risk. We do not provide activation keys for it as well. If you need newer versions of Techstream you can try to find it via external sources online. Again, support is limited for this item and only covers the hardware. No software support will be provided. If the software you acquired does not connect to your vehicle, chances are you have the incorrect or incompatible version, which is NOT indicative of a faulty cable per se. You may need to research first to find out which Techstream version will work for your vehicle. You must also take into account the model year, chassis and the market where your vehicle is released in.

Does this software work with Australian models?

Yes. It is compatible with most* models worldwide in all regions.

Can I program smart keys?

Yes you can, however, you must have the original smart ECU in your vehicle*.

Does this work with Windows 10?

Yes. We have tested and confirm that it works on Windows 10. Please make sure you have the latest version of Java installed. However for ease of installation it can be better to run a virtual machine on laptop.


*Some features may not be available on some models and makes, and some models may not be available in the software as well. Please get in touch with us first to ensure compatibility when in doubt. We will need your VIN and the function you are after to determine if compatible. Returns due to a buyer’s failure to first confirm with OBD2 Australia compatibility on this vehicle will be subject to our Returns Policy and Terms and Conditions. A special software update is and may be required to enable some features and functions. The software update is available in Windows only. It is the responsibility of the buyer to execute and apply the software updates.  A return with a reason ‘the device was not updated’ will be subject to our Return Policy and Terms and Conditions as this does not constitute a ‘faulty’ or ‘defective’ device.  

*Some functions on Techstream require a cable that has a firmware version of 2.0 and above, and any cable with a version below this will not work. It is imperative you do some research first to find out if the function you need requires which Techstream version and which cable firmware version.

 Video and photo proof is required for any claim of this product as not working. The video proof must clearly show and demonstrate the claim. 

Returns and refunds due to incompatibility (without or against OBD2 Australia advise, or refusal to execute troubleshooting/provide the required proof) will be subject to our Returns Policy/Terms. By purchasing this item the buyer confirms to have fully understood and read the product limitation.

Works for Lexus IS300h 2014. Only catch at first was that Techstream wanted a key entered when changing from default North America to Other (i.e. Global) region. The key was in a text file "Key If Techstream Asks" that appeared on the desktop of the Windows XP virtual machine. Would assist if the key entry step was added to the instructions :-)

  1. Received in good order and in timely manner. Instructions were helpful and the cable interface appears to be recognised by software although am yet to connect to vehicle. I don’t expect any issues when I interface with the vehicles interface port.

  2. Great product and once I purchased an adaptor cable it worked well.

  3. Came in a day and worked mint for a 186 crown 👍

  4. Great product. Received in a timely manner with good communication and correspondence from the company. The M-OBD2 cable works 100% with Techstream on Landcrusier HDJ100 without issue.

  5. Works as it should
