@del_boy can you please elaborate more on this point regarding the select serial monitor. Are you meaning to set via service tool (bridging the pins on the black CANBUS plug - i have already confirmed the CH 1 & 2 are on. Alternatively once flashed Teensy i can go to Tools/Serial/Monitor but there is nothing specific there showing post flash. In looking at the code within Ardinuo IDE for the Autosteer AOGV5 Mod on the “Can All Brands” Tab i can see NH referenced but dont know if something needs to be modified specifically in the firmware for NH. Many thanks!
