Hello I drive a 2016 389 triaxle. My question is how hard is it to update the gps. I drive for someone. I was able to download new updates per the garmin/paccar website to a flash drive.. My boss wanted me to call dealer to make sure that this is something that we can do and would not void warranty. Dealer said that they have to do it. I call B.S. on that but what do I know. So it is at dealer and they are having a hard time they are saying that they are not able to get to the first step to down load. How many of you have done the down load yourselves and how easy was it.
Thanks
Sal.
