Hello Steve,
I am sorry you feel this way.
I can assure you we spent a great deal of
development working with roundabouts and UK
specific issues with 4.0. Yes there is room for
improvement and we are always looking for ways to
do this, as you said it would be nice to have
"take the 3rd exit" when dealing with
roundabouts, this has been noted in our feature requests.
Yes there are incorrect POI data from TeleAtlas,
all we can do is report the issue and its up to
TeleAtlas to fix it, and when we get the next set
of POIs from TeleAtlas hopefully they are
fixed. Incidentally I am currently trying to get
updated POIs for the UK but TeleAtlas has changed
the internal format of these POIs so now I have
to not only just convert the POIs to our format
but now have to develop a new intermediate
conversion utility that changes their new format
into the old format my software is expecting. So
I totally agree with you that TeleAtlas's
practices are someone in question here and am
also disappointed in their data quality. Sendero
may have to look into other options, which will
present itself with a whole new set of obstacles
and may trade on set of problems for another.
Also keep in mind Steve, that prior to 4.0 the UK
only had a very limited set of POI data, now you
have over 15 times the data as before, and some
of it may be bad, that is life, all we can do is report the issues and move on.
As far as your comments on pricing goes, feel
free to buy those other systems and let us know how that works out for you.
Thank you
Respectfully

With increasing experience it is becoming
obvious that there are many severe problems with
the UK maps. Many POIs are out of position by
very large amounts. Some roads appear to be
fragmented and the information given for
'complex' junctions like roundabouts and
motorway entrances and exits is often so wrong
as to be misleding and certainly could not be
relied upon to give a driver instructions.
I am surprised that some of the POI data has not
been corrected. Commercial concerns cannot be
happy if their positions are shown as being more
than a few yards out of place. I have examples
of errors where the POI is round about a mile from its actual position!
I am not sure if the presentation of 'complex'
junction information is totally the fault of
TeleAtlas or whether Sendero has a hand in the
problem. For example on leaving the M4 at
Junction 12 (Reading Central) the instructions
given are to turn left on to the slip road and
then left on to the roundabout at the bottom of
the slip road. There needs to be a further
instruction telling you which exit to leave the
roundabout by. You could want to go left (south)
toards basingstoke (first exit) or North towards
Reading (third exit). The second exit takes you
back on to the M4 heading west for Bristol!
So although V4 has seen a great improvement it
has introduced a number of new problems - some
of which should be fixed by a free update of maps.
I wqill need a lot of assurances before spending
£120 on another upgrade if the maps are not
improved. Incidentally this is approximately 15
times the cost of a new road atlas and 6 times
the cost of buying a new updated CD of maps for other GPS systems.
How is anyone finding life with Wayfinder which also uses TeleAtlas maps!
