why does TomTom ignore a road.

pwest

I'm trying to plan a route. I can plot it on myroute app exactly as i want it. However, when I transfer it to the TomTom it alters the route I've planned and will not use a particular section of road. It shows it correctly on myroute app but the downloaded track shows a deviation I don't want. Google maps lets me plot the route I want exactly
It only happens on a particular short piece, but it happens to be a bit i want and the deviation goes via a main road. This is driving me to drink!!
Why is it doing it

Note. I've published the route that myrouteapp permits. If one tries downlading it to a Tomtom it will alter the last few miles to cross the M11 twice.
What is going on?????

I've tried that. I've used Mydrive to put 4 stops along the length of the piece of road it ignores (a couple of miles) and Mydrive plots the route correctly. I then save it as a track to my device - and when I look on the TomTom it has completely ignored these stops.

Another point..... I've noticed it won't save it as a track, only as a route. Presumably it can't save the track 'cos it can't use that bit of road - and as a Route it simply creates an alternative route that it can plot. It would appear that the TomTom map database simply doesn't have that piece of road included.
