Settings GO 520

[LesEvans]

Can I avoid minor roads ?
I recently , yesterday, drove from Aberdeen to Fort William.
My GO 520 was a nightmare - worse than useless.
It continuously took me off dual carriage ways and sent me down minor roads (single lane with passing places) when I'd be better off staying on the main road.
I am set on fastest route !
The unit is a crock.

What is your setting at Route Planning?
At "Always plan this type of route" select "Fastest route".
This should, if along the fastest route, select M; A; B roads Keeping in mind that some A (M) are faster than some straight M roads.

I get Aberdeen to Fort William on a GO 620
A96 Inverness
A920
B9014 Low Road
B975 Castle Road
A941 Station Road
A95
A889
A86A82

I don't know the lay of the land but it seems to think that cutting over from Hunly to Craigellachie via Dufftown is faster than staying on the A96 to Keith.
On the other hand, it comes in at 3:47 hr and 153 miles while Google via Keith shows 3:33 hr and 155 miles.

Thanks for the response:-
Perhaps you missed the note - I am on fastest route setting.
Your route confuses me.
The A944 out of Aberdeen is the route.
What was happening it was putting me off the A’s onto very minor roads.
On looking at other forums it appears this is a long standing issue that has not been resolved.

It is not my route, it is TomTom when the start is Aberdeen and the finish is fort William.
If no specific location is given it is usually from city centre to city centre.
The first two is how Google does it.
The next two shows how the city is selected on the GO and the resulting route.
The last two show the GO start and finish locations.

Now use yours and program the route, then tap Menu > Current route > Show instructions and you will get a turn-by-turn list of road names/numbers.

Thanks Appreciated.
However my question still stands:-
Is there is not a setting to avoid minor roads ?
Fastest route doesn’t achieve this.
On fastest route I was taken off an A road dual carriageway and diverted onto a single track road with passing places.
My understanding now (after reading other forums) is that this a known TomTom issue whereby the ‘fix’ would be a software update.
I have contacted TomTom customer services and await their response.
Thanks Again,

Quote from a forum:-
“”This has been the problem with TomTom since the very begining, and the main reason I've started using google maps.
Country lanes in the UK are listed at 60mph. But most cannot be driven down at more than 20mph (narrow lanes etc), some even are impossible to drive down.
Unfortunately TomTom sees these roads as 60mph, so it assumes it wil be quicker/shorter.””

Cannot help you with that but as far as I know all upscale models apply IQ routes.

You can easily confirm you suspicion about the high speed on those lanes by programming a route over one of them and go Menu > Current route > Play Route Preview to see at what speed TomTom thinks that route should be taken.
Example, over here the Toronto centered "M" road has a speed limit of 100 km/h. Until a couple of years ago a Demo would run at that speed. Except for rush hour the typical speed on the passing lanes is 120 klm/h and TomTom's Demos runs at about 115 km/h, a fair approximation considering the few cars driving at legal speed.
