I have waze and a garmin 890. Truck nav is pretty much useless given the other two options. It does get interesting when they don't agree and I have I have to use that normally dead space between my ears.
A couple of times when towing our trailer (65ft combo overall) we hit stopped traffic. Luckily a call to onstar and they were able to download a turn by turn route to the gps around the traffic that was ok with the trailer.
The first time it was in an area I was familiar with and new the "typical" route around it was NOT a route for our trailer combo, and onstar downloaded the route I knew was ok with the trailer.
Other than that I agree, most vehicle GPS systems aren't as current as stand alone or google.
