Is This the Right Scan Tool for You?
Choose the ST400 for basic Android or Windows engine diagnostics from a locally supplied adapter.
Choose the ST350 for Leaf Spy or Dr Prius, or a full-system tool for ABS, airbags and service functions.
The instructions that came with the product were quite vague as is customary with anything car related. Eventually got it to connect to my phone via the car scanner app on android after a lengthy process of trial and error. Was able to create a custom gauge cluster on my phone which is what I wanted to do. Good product for the price.

I'm very pleased, I had asked during my initial ODB2 purchase that intended to monitor the battery condition of my Outlander PHEV, and was advised on the correct model to allow me to do this - on taking this advice the team amended my order and the shipped me a product that was able to provide me with the correct information. (Thank you Nick for your support)
