Thank you for question.
If you are talking about CAN bus data adapters we can recommend to use LV-CAN200. How many and which parameters you can get from your vehicle depends from your vehicle. If your vehicle is supported, you can check in out Teltonika WIKI page: https://wiki.teltonika.lt/view/CAN_adapter_supported_vehicles
If your vehicle is supported and you want to know parameters or you want that our partners will make wiring scheme if your vehicle is not in supported vehicle list, please contact your Sales manager.
I don't have a "sales manager" contact. I've used the form on your website about 3 times in the last 20 days, but I haven't received any answer...yet!
