Summary: Had one or two problems at first updating the maps but once completed it has been even more useful. Occasionally I have missed a turning because of the distance of an exit which seems to be measured to a roundabout off the major road.
Summary: Bought as first sat nav. Does the job but very expensive to update maps after first year. Roads change so frequently that this soon becomes a major issue. When buying future sat navs I'd look more carefully at long term options.
Summary: Had this for a while now, and recently paid a one-off fee for permanent updates. Did cause a problem when we headed to Wales and the town we wanted was not detected. Took a while to realise it was only looking at England rather than the UK! A change to the programme and everything was fine.
Summary: Bought this for my wife, who previously had a TomTom sat nav. She appears much happier with this product and the fact that it offers more facilities e.g. names the roads and motorways you are approaching. looks good too.
