sat nav route

[david21]

hello,
Can anyone tell me why when travelling back from my friends i set my satnav from enfield(north london) to glasgow(take me home setting) and it took me up the a1 motorway to scotch corner, across the a66 on to the m6 it took nearly 8 hours and this was on the 'optimum' setting,looking back on it should it not have just took me m25,m1,m6,m74.
i travel a lot from milton keynes on this route(visiting family) and can do it in about 6 hours,is it to do with the setting or where i stated from.?

Depending upon exactly where you were starting from and going to your satnav might have calculated the distance as very slightly shorter.

The AA route planner quotes central Enfield to central Glasgow as 401.9 miles and gives the route you've suggested would have been best. However adding a 'via' point of Scotch Corner Services only takes the total distance up to 404.1 miles, using the route your satnav gave you. (i.e. just 2.2 miles further). So, in terms of distance, there's very little difference in it (although the AA site does give the former journey time as 6 hours 37 minutes and the latter as 7 hours 12 minutes).

Your SAtnav will give you the most direct & shortest route

thanks guys,i if i do it again i will put via milton keynes, it may just seem quicker as this is 3 and 4 lane motorway were as the a1 is mostly duel carriageway and what feels like slower traffic.....thanks again.

If you know the route, why do you use your sat nav?

Hopkirk,
It has built in traffic master (the charging cable acts as antenna ) and will reroute if needed,It does this for about a 100 mile radius,it also has good p.o.i such as comming off the motorway for a few miles and paying £1.12 for petrol instead of £1.25 or getting something decent to eat.
