It's also a good idea to review the whole route before setting
out, to make sure that the GPS isn't taking you 100 miles further
than necessary just to save 30 seconds of journey time.

How would that work?

Assuming that you ask for the fastest route, it will look at a lot of
alternative routes - which may differ in distance by quite a lot because
some are fairly direct but over slow minor roads, and others are much less
direct but use faster motorways. Having done all that, it will pick the one
which (it believes) will get you to your destination soonest, even if by
only a very short time and even if the distance is far greater. It is, after
all, only a stupid computer with no inate common sense!

I have often found that, when left to its own devices, my TTG will choose
considerably different routes for the outward and return journey simply
because having to go 270 degrees round a particular roundabout in one
direction but only 90 degrees in the other tips the balance, and a totally
different route comes out "faster".

So I *never* blindly follow the route it has chosen before first reviewing a
map of the route on the screen to see whether it looks sensible. It's easy
to ask for an alternative route and compare time and distance if I don't
like the first one. Quite often the alternative is a lot shorter but only
*slightly* longer in time.

yes.. what is missing is a function that would bring up a display that
showed the alternate routes with columns showing time and distance.

and yes I've noticed the same thing. sometimes a mere mile or a mere 2
minutes can make the difference.

this is one of those things .. that is evolving as customers find out
more and more about how the functions work.. and the manufacturers
learn that their programmers instincts perhaps were more from a
programming perspective rather than an end user perspective.
