The 'no Highways' thing isn't necessarily
JUST down to the GPS unit or its software settings, it can also depend somewhat upon the map package your GPS is using and the labels that particular mapping software has placed upon the roads or highways that it shows! And the particular 'map' the GPS is 'looking at' for any given instant can vary depending on where you are or how close the GPS view is zoomed in, or how far out it's zoomed! :shocked:
I've seen the 'Highways/no Highways' thing &/or other settings change the directed route in the middle of running a route that was planned on a city to city basis beforehand, but as the zoom level changed when we actually reached those cities, the selected map changed and the labels the different scale maps used meant the settings in the GPS kicked in & directed us off the city centre by-pass & out into the back streets, potentially adding significantly to the time & distance we would've travelled if we'd not had a general idea of where we needed to go; and in other instances the settings in the GPS have meant it tried to avoid the straight forward 'town to town' route well off any major 'Restricted access Freeways', instead trying to divert us waaaayyy out into the boondocks, simply cos the map being used had that 'normal 1 lane in each direction' road between towns labelled as a 'Highway' cos some bloody town councillor was a pretentious pratt who thought it'd make his town more interesting if it was only accessible via a 'Highway' or two!! Luckily, or maybe due to proper preparation & prior planning, we usually have a reasonable idea of where we want to go & so can ignore the spurious directions until the GPS catches up with us, which it invariably does!
But that's really because, while I have it running (muted) ALL the time, I only use the GPS as a guide & reminder for the route I've researched & planned beforehand or to get home from some back roads meandering, altho I will admit to sometimes using the turn by turn instructions to find specific addresses. But then, here in Aus we have lots of wide open spaces with relatively few towns on the map & in many instances, even fewer people; so if you are travelling outside the major routes between cities here, you'd be a fool to
RELY on your GPS exclusively cos it's so easy to simply follow the line on the screen into nothingness or take a wrong turn & end up lost cos the GPS maps don't have great coverage in the particular area..... Yeah, we do occasionally get those who do just rely on their GPS units, especially their telephone based GPS's or even worse, their 'around town' City Navigators or whatever on their phone or otherwise, but we generally don't hear about them until they hit the headlines later on, when some other better prepared traveller or a stockman/outback worker finds their bodies some months or even years later!! :shocked:
A GPS is a great tool to help you follow a pre-planned route or get home from one of those 'meandering around the back roads' trips, but it
is just a tool to help you get the job done or make it a bit easier...
