Happy New Year every one.
It is not the GPS, it is clearly the database, and short of a detailed
survey of every address there will be variations. As Google enhances it's
database I am sure so will the Navigator sellers. We have come a long way and we
are getting spoiled.

first, a happy and hopefully healthy New Year to all of you.
I think, some of you are going slightly overboard, in what you expect a
$150 Dollar car navigator should do,
I also don't believe some of you you realise what exactly it was
designed to do.
It is not a device to accurately shoot a missile trough somebodies
toilet window and hit a specified turd in the bowl.
It is designed to get you relatively easy and close to a specified
designation. preferably when used in a motor car
This it does perfectly well. It may be a few meters out from an exact
house number, but it got you there without you having
to look at the map, (or worse get your spouse to read the map and
It improves the road safety, especially at night time, when you often
don't see the street names and have to slow down to a crawl
with a lot of cars bunched up behind you.
The mind boggles if some of you think because the GPS is not 100%
accurate, The Fire brigade gets either lost, or tries to extinguish the
house next door to the burning one, just because the GPS is 30m out.
What you're actually are saying is: The Fire brigade is full of idiots.
To sell an item for 150 or so Bucks, on can not reasonably expect it
to be as perfect than another item which sells for 100 grand or more
except a few government institutions can afford it.
Not every instrument is mad by Agilent for a cost which is prohibitive
to the normal punter.
Just get back down to earth, a few years ago you had to learn how to
read a map, or follow the often useless instructions somebody else gave
Now for hardly any money, you get to your destination with least amount
of effort and a lot saver than before.
