Given the spotty nature of the hardware the IVIS runs on I don't think I want it trying to navigate for me as well. I could be wrong on this, but is it possible there are government regulations about ELDs not being allowed to be used for other purposes such as navigation? In feeders we only have a few stops on any given day, and I've never had an issue using my phone for navigation information or asking for a map from dispatch. CPU jobs are probably the only type of work where a navigation system makes sense, but in my area most of our city pickups are located in easy to navigate large warehouse parks with plenty of places to turn around if you miss your address. In sleepers I know of several teams that run with an official truck GPS nav unit, but since we go to the same buildings week after week I never saw the point of having one. Bottom line is we probably don't have them because its too much work for too little benefit. Just use good judgement and plan on where you will be going before you get there.
