Have a new TomTom 400 (with the most recent firmware version) which I use for rides where I never want to take the nearest of fastest way. I add the route with a minimum number of waypoints (stops) to coax the satnav to give med the exact route desired, as displayed on the map.

After start, it often gives me erroneous directives to turn off the route I have stored. If I simply ignore these directives and go straight, it will revert back to the correct route until sometimes later, when it does the same over again. If it wasn't for the fact that I know some of the routes beforehand and simply ignore the directions to turn, it would lead me the wrong way.

It doesn't seem to matter how I set up the route, i.e. directly on the satnav or via mydrive and upload to the device. The behavior is the same.

My settings under Route Planning are:

Suggest destinations - Off
When a faster route is available - Don't ask me
Always plane this type of route - Avoid motorways selected (all other deselected)
Avoid on every route - all four switched On

What can I do to get it to stick to the intended route?

If it was static it would be a track.

So yes a track it's like a recording that you can replay later... There's no calculations.

Note that a track doesn't have any waypoints. It only has a start and an end...

On the device no, you can only design routes.


If you need the versatility of a route but you want to guide the GPS to a specific course, you may use software like Tyre that will make your life easier by adding the necessary (intermediate) waypoints. You may design a track and then reduce the number of waypoints automatically. Don't forget to check that the route is ok on the device. Different maps (Google & TomTom) and different route calculation settings may affect the final route...

This is what I do.

That may clarify how things are:

Of course there are always things that may improved...

    Try these setting
    Ask me so I can choose on
    Fastest route on
    Toll roads on
    All the others off

    And put in more way point as this new unit tries to think for itself

    And as you are finding out it is not always very helpful
    Check that your route is not set to the very snakey type roads otherwise you could end up on some very unsuitable roads a surfaces

    You need more waypoints to guide it. Otherwise it will calculate the shortest route (in distance or time, depended on your settings) between your waypoints.

    There are some useful tips in Tyre's manual...

    Thank you!

    What gets me if that's the case, why does the TT display one route to start with, while advising me to take another once I'm on the road? It could have figured that out as I plan the route and show me what it intends to do, so I can correct it up front by adding neccessary waypoints. To me this is a serious software bug.

    No this is normal. Routes are dynamic. The route calculation depends on the traffic conditions, and other factors, even without Live Services.

    https://uk.support.tomtom.com/app/answers/detail/a_id/9552/~/about-iq-routes

    You may also alter the result by selecting different route types (faster, shortest, etc)

    You may also use a track.

    I find this difficult to accept as I have no use for a device that refuses to take me on a route of my choice! If there is no way to do that, other than adding an arbitrary number of waypoints, this is a truly user unfriendly gadget.

    The routes I'm riding are in the countryside with absolutely nothing "dynamic" to them. The TT is not connected to anything but 12V and satellites and has no idea what's going on around it. I have not selected fastest, shortest, curvy or hilly - but whatever you select, it should display the result at the planning stage and not later.

    As a minimum there should be an option to disable any unwanted "intelligence" to have the device to do exactly what you ask it to do and not follow it's own logic. Perhaps the Zumo does a better job at this?

    Routes are always work like this on every device. It's a list of waypoints and the device will calculate the route between them according to your settings and map data.

    If you don't like this then use tracks. They work as you want.

    I have no problems with the calculation of routes between waypoints - but why can't it do it at the planning stage as it has access to settings and map data - all being static?

    Ok - so using tracks will bypass the dynamic replanning of the TT? I know you can create and upload tracks with mydrive but can you also do it directly on the device?

    Thank you so much for your help!

    I have no use for waypoints as long as I can set up the exact way I want to go and what I see becomes what I get. I will use track from here on.

    Unfortunately Tyre doesn't seem to be ported to Mac while I am a Mac only user. I will use mydrive or a simple iPad app that creates GPX files that I can upload to the TT through iCloud.

    I'm using Tyre through VMWare Fusion (PC virtual machine), but also MyRoute-app a web app by the makers of Tyre. Try it.

    I may do so but mydrive and InRoute (IOS) both do a decent job in setting up a route and generate GPX files that contains both route and track.

    One last question:

    The TT has a setting described in the manual:

    "When a faster route is available"
    If a faster route is found while you are driving, TomTom can replan your journey to use the faster route. Select from the following options:
    - Always take the fastest route
    - Ask me so I can choose
    - Don't ask me

    I would understand if I had the first option selected but I'm using the last. This translates to me as "Leave me alone, I'm not interested in the fastest route" Why does it then insist on calculating a faster route between waypoints? The options are not explained in the manual however.
