NT200 is specially designed for DIYers to get easy and quick access to engine problems on all OBDII compliant vehicles sold worldwide since 1996.
One of the reasons I bough this device was the option to update via USB. However, the updates in the device's webpage are rather older than the software which comes in the scanner. The scanner came with V1.6. I did downloaded the latest update in the device's webpage and performed the update. Now my device is showing V1.5.
Other than that, I had have no problems with this scanner. It is very easy to use. It is all that you need in order to ensure you will go thru the emissions test with no problems. It not only read and reset the faulty codes, but also shows you the readiness of the systems for the emissions test. It also shows live data from different sensors. It is amazing all the information you can read with this affordable device.
