I have created an itinerary through google maps, a specific route that I want to take instead of the route that TomTom suggests. I load the itinerary in my TomTom One XL & it's done. But it will always ask for a travel type, such as Fastest, Shortest, Avoid Motorways, etc. So regardless of which type I choose, it will calculate it's own route again & completely override the route that I created in google maps. Why is that?

Is that what you think happens, or did you actually try it? Because as far as I know, the itinerary planner uses 'via' points to make the route. And the TT should plan the route in such way that all 'via' points are included. The route between two 'via' points can be calculated as Fastest, Shortest etc. But it shouldn't skip any of the 'via' points.

Sometimes you need to add a lot of waypoints to get the itinerary you want. Each mapping service uses its own route finder and TomTom's seems particularly keen on avoiding minor roads, so sometimes it will plan routes that aren't what you'd expect based on the waypoints. For example, I recently wanted to avoid joining a motorway for as long as possible so I specified a route that I thought would be fine, only to find out that the TomTom wanted to take me on to the motorway two junctions early and then take me off for a ten-minute round trip to my waypoint. Always test your route on the satnav first, and add more waypoints as necessary.

It actually does do it. I've tried every way possible. But I plan the routes using Google Maps & then convert it to TomTom's .itn file. Could that be the problem? Are you talking about planning the routes in TomTom Home instead?

How many waypoints are in the .itn file? How do you convert from Google Maps to an .itn file? Could you perhaps upload the .itn file somewhere? Then I could check it to see if I can find the problem.

I think the answer lies within the map itself. Seems like 1 of the exits of a highway is not on the map, so TomTom doesn't register it & routes a new route which is even further because of the next exit & then loops itself back around to get back to where it was suppose to go in the first place. So that's why the route is always different to the 1 that I planned through Google Maps. I will test it out while driving to see if it really works.
Thank you very much for your help though. I'll see how if it's fixed the problem or not by actually going there
