loaded with APP 9.051
OS 483784

gps v1.2 boot 5.3026

just want to know is there any way to tell TT to stay on main highways ,we have just come back and wanted to stay on highways but TT told us to use some other road and seeing we dd not know the area we took it ,it may have been shorter but hell it was not faster ,on way back i changed to fastest rout but it still wanted to take us down same road ,not a good thing when pulling a caravan ,is there a settings or is it look at maps first and use TT as a backup for city driving
many thanks
