Hi all
Have insite on my pc and I’m using a nexiq usb link 3
When trying to connect to the vehicle you get message to update the firmware in the usb link, click ok and then it says Cummins was unable to install the update. I can’t seem to find anywhere that you can download and update the adapters firmware away from Cummins. Any ideas? Cheers

You have to get the firmware updates from the nexiq website not from cummins.
