Is there a difference the way a route is calculated between Sat Navs? Multiple riders used the identical route edited in MRA, edited as TomTom, compared with HERE & Open Street maps, everything was checked and double checked, differences and errors were corrected
While on the TomTom Rider 550 user was directed on an unnecessary detour while other users (older TomTom Rider, Garmin Zumo XT and TomTom GO) were routed faithfully to the MRA route.
Is there a setting on the TomTom rider 550 that could have meant that it interpreted the route differently? Why were they the only rider that was sent on this detour?
