Can TomTom please add something to the next Sat Nav software update, the facility to adjust speed on roads.
I did an experiment on a long journey with my Start 50, staying at 70mph on the Motorway 250miles and the Arrival Time went up by 20mins. I would therefore have to break the speed limit to arrive at the time on the Sat Nav.
A setting to adjust the vehicle speed for 60mph on a 70mph road, 50mph on a 60mph road.

Try checking your route prior to leaving with Google maps as that will show any hold ups along the way plus the anticipated additional time or just start out earlier and if early stop for a cuppa near your destination to relax.
On my 400 I find that the destination time is varying all the time depending on the speed and traffic conditions.
To help for a 60/70 adjustment + 1/7th 50/60 + 1/6th etc to the time shown on the your unit.0 -
