After all the post and my experience on first run of new CX21 , it’s obvious the gas gauge can’t be trusted . On recommendation of salesman order vessel view mobile . Now the head scratching is that it appears to already have a module plugged into the harness plug.

..Not blue tooth obviously, is this to feed one of my graphs and the salesperson forgot to tell me ?

Below is the module # , the Bluetooth module I have is a 8M0115066 , 489651-4/12/22

8M0056665
480082-8/13/2021

thanks ahead
