It's important to note that ALL vehicles running Navistream in the US or Canada  have a properly functioning ECM connection. If this is found to not be the case, your Drivers can be placed out of service and/or fined by the DoT/CVSE in contravention of the newly mandated use of ELDs. There are provisions for vehicles that have electronic logging devices (ELD) installed prior to that date as a path to compliance. But, that will run out on Dec 16, 2019 when all Carriers will need to be fully compliant.



So, what should you do if your vehicles don't have an ECM connection, or that connection is bad/intermittent?
