I successfully bought the scanner, before a business trip, I was driving in my car. In order not to spend extra money on the service, I checked the diagnostics myself, and indeed I like to dig deeper in the car. I found the connector on the Nissan quickly, it is inserted neatly, the whole connection is simple. Errors, checking the entire system, did not reveal, the check took a few seconds. I also looked at various information on the car that the scanner gives through the application, it is very informative (I downloaded the car scanner application).
