Truck Gps Timing Vs Phone Gps

Wondering if anyone else has this issue or it’s just the way my gps is. For time estimates and route corroboration I’ll put an address into my truck gps and phone gps. I also check routes with my rand McNally. However, my truck gps will consistently show several hours difference than my phone gps, whether I select loaded or unloaded. I’m not governed, I’ll do the speed limit, but no matter what it’s always off.

If you're using Google maps or anything of a similar nature it's assuming a much more consistent and higher speed, and sometimes the roads it routes you on can take miles off the drive, depending on the area of the country. I find when I'm doing my trip planning I'm anywhere between 2 to 4 hours behind Google's estimate

Also I dont know if there's a way to change it on Google maps but that takes you on roads that may not be truck friendly. Could be a big part of the time difference.

I've noticed my google map gps takes the speed limit into consideration and makes my trips shorter. My Rand McNally has an adjustment and is much more accurate on the eta. I sometimes use both since my google maps has real time slow downs for accidents and will re route me. Neither one is 100% reliable.

Truck GPS units like Rand McNally and Garmin can be set for fastest route or shortest distance. Depending how yours is set will make a difference. Google maps is great for it's satellite views, but dangerous for truckers to follow. Rand McNally can see traffic if you can use your phone as a hotspot and connect your RM to the internet that way. Garmin uses an app and Bluetooth to see traffic. I use Trucker Path to see the traffic coming up as well. Having Trucker Path open allows me to also see parking, rest areas, truck stops, weigh stations, Cat scales , Walmarts and more on the map. Hope that helps.
