Hay all wouldn't it be great if when you put in your vehicle details in. IE Motorhome, and you put in the weight the speed limit adjusts to that vehicle. My Motorhome is 4.25 ton so over the normal 3.5. My speed limits are lower so 30, then a 60 road is 50, duel carriageway is 60 then motorway is 70. Be nice if it would come up with those speeds instead of the normal car one's. Is there anywhere we can make suggestions on the TomTom site ??
