my impressions after 12 months of usage

TomTom one v4. Removed old tomtom speed camera POI's. Installed pocket GPS cams. On the whole, very pleased, here are my findings.

1) despite having the POI's set for route only. When following a route, I always get camera alerts on near by roads that are not on my route - very annoying.

2) can the POI's not be clever enough to work out your travel direction and thus only show cameras on your side of the road? I suspect this is a limitation of the software OS rather than pocket GPS POI's.

3) occasionally I will a get a verbal alert repeated right when travelling over the POI location. Seems pointless. Usually when lots of POI's close together.

1. The software uses a cone shaped "angle of acceptance". If you therefore use a large enough warning distance then it is possible for the base of the cone to include nearby roads.

3. Because the software can only handle 1 warning at a time, it has to pass the first location before it can proceed to the next. This is most noticeable when travelling on dual carriageways, when there are 2 adjacent cameras marked on an over-bridge.

1. Also, TomTom have changed the definition of what is "on your route".

For example, if you are travelling on a major road and pass a junction, the entire slip road and roundabout etc. coming off the main road are now included.

I believe this was because the TT "missed" many of their own POIs such as the Motorway Service Stations, which are obviously some way off a junction.

Unfortunately, there are often cameras or mobile locations on these roundabouts so we now get alerted for them spuriously.

Blame TomTom.
