I've had mine for a year and here's what we got. It tries to route be down non truck routes while telling me the truck route is illegal for me. This is such a bad problem that even Interstate 25 in Denver Colorado is listed (according to this GPS) as a non- truck route and will route you through the city instead. There are several drivers within our company who own one and more than half (of about 50) have crashed to an un-recoverable state. Our company representative said that Rand McNally informed them that the GPS was not designed to say on for a long period of time. Really? it's a truck driver GPS. We have one driver with a $2400 dollar ticket due to this GPS routing him down the wrong road. The companies response was to update the unit. I've had mine for a year, I never noticed one update that corrected functionality, they only seem to keep messing the tools. I want a GPS that routes, if I wanted tools I'd buy software for my computer.
