Try this test, turn off on a street not chosen by the truck route and see if you get a notification/warning about it. Please use the term NextGen and not iGO when referring to it. The term iGO/Primo is for old generation product. I know NNG stupidly call NextGen as iGO Primo NextGen (yeah that's it's full named on their website) and it's confusing (and they call Primo as iGO Primo)
