2014 IS300H - how to check software / media firmware versions?

Recommended Posts

Hi All

Does anyone know how to check software or firmware levels on the 63 plate IS300H  premier model? 

As part of buying a approved used car I wanted them to update this if out of date but the reply I got was a bit vague, be good to know how I can verify myself if its not the latest version 🙂

Usually, when you enter your VIN and GPS serial number, the Lexus website will tell you which tools and firmwares were installed from the previous owner. In my case everything was installed and I was surprised I do not have to do anything unless they release something in the near future.

The process itself is very well described into the guidelines and takes ~1hr.
