    Default Route Calculation - seems odd

    Hi, i'm a total new user, just purchased a pre-owned 2012 Kia Carnival - and its onboard Nav was years out of date - So I've installed iGo Primo 9.6.13.405512 with HERE 2020H2 maps for Australia onto SD card and gave it a try
    and after much reading of various threads on here , I've sorted many of my initial issues.. but one thing remains...

    The route it chose to send me on, during a weekend trip from Werribee to Warnambool a trip of ~ 3hours and 230KM's. Regardless of whether i chose Fast,Easy,Short or Green , it would persist in wanting to leverage B & C roads... now our local C roads may well be sealed, but they are narrow, and poorly maintained, so we would have preferred to have stuck to the Motorway & Highways.

    Here is a table of the Route it chose , along with alternate routes.. the final line is after i manually entered a handful of waypoints to FORCE it to stay on Highways.

    I have subsequently discovered i can 'trick' the Nav to use my 'preferred' route , without me adding waypoints, if i set my profile to 'Truck', rather than 'Car', however - if i change the Truck profile maximum speed from 80KM/hr to 100KM/hr it again goes back to choosing B&C road routes. I've seen in one of the stickies relating to sys.txt , there is an [defaults] entry known as mainroadness=60 .. I've tried differing values for that setting - but it didn't have an obvious effect.

    Does anyone have some suggestions on how to better favor using main highways and roads , over B & C roads ?

    You need to adjust the software a more carefully.

    Don't pay attention to the look of the software, it's the same version, I just added the skin I'm testing at the moment

    - you adjust the vehicle parameters yourself (max speed on highway, local roads...)
    - turn off the use of the online service
    - The quality of the map and their accuracy the story is for itself. Try another provider (TomTom).

    By the way, don't pay too much attention to the trip duration predicting, it's just there to point out the time frames and route differences.

    Many questions become very arduous, a lot of time chewed deja vu...Since we have lost all the year of work and effort, many people have no will to answer the same questions again. Me neither. Use a search, please.
