TND 760 will NOT work with 2017 Model year vehicles. in 2017 Most Manufacturers moved to a 500K ODB connector from a 250K. The Rand 760 will not work and they have no plans to support the new OBD type 2 connector. so if you plan on getting one of these consider the tractor you may be driving in a few years.
I have 4 of them I bought in the last year and now they are paper weights since I moved my drivers to 2017 Cascadia's. Oh and the new type 2 OBD was mandated in 2011 , so you would think someone there should have known that.....Their advertising doesn't state that
