Long before mobile smart phones, truckers were using apps like copilot gps on their offline laptop for just this. I used to have it on a laptop for install work I did. In fact, I continued using it in areas with no cell coverage. Another app I used was Microsoft Streets and Trips. In 2006, they added a GPS version that did turn by turn nav.

That said, the point still stands. I did some searching, and Streets and Trips are discontinued. Copilot was bought by Trimble and AFAIK, you can only get the mobile app versions (they still have offline support). I think their truck fleet software will still run on laptops, but are sold as part of a bulk purchase.

I did find MapFactor, which I've never used, as being something that will work on Windows and Linux (via wine) and it provides real-time GPS navigation.

There are still more than a few great turn by turn navigation libraries that run on ruggedized windows tablets. There were two that escape my mind.

Quite often they work completely offline, and also cover more information related to topography and driving routes that may not be traditional roads on existing maps. For example, the path to a location in a farmer's field, etc.
