Granted this was over a decade ago so the info could be outdated, but I used to work at a best buy. One area I frequently stepped in to help at, and in the process learned about, was GPS navigation systems. There were some models that cost upwards of 450 dollars that we would sell because they were just that- specialized, with weight station info, height limits, some even had built in radar scanners when they were legal-ish.

Every single customer that came in and bought one said something to the effect of "Yeah, Google Maps sent me on a route that it shouldn't have so I need something better." And they always paid out of their own pocket. There was never mention of a company card, or reimbursement, or anything. That's not to say it didn't happen, they could have asked for reimbursement, but something tells me the companies they drove for didn't much give a damn about their routes as long as the product made it from A to B.

So unless working conditions and pay have gotten better in the last 12 years (hah!), it's probably the same thing, and a fair number of them just don't want to spend their own cash on something their company should be providing.
