Navigator 111 Speed Camera POIs

[ALEXG]

I have a BMW Navigator 111 . I thought I had successfully installed the GPSW Speed Camera POIs . Every time I approach a speed restricted area , my systems is picking up the limit as if it were in KMH and converting to MPH. ie when approaching a 40 MPH limit it warns of an approaching a 25MPH limit. Anyone know how can I solve this ?

IIRC when you download the POI's it asks what units you want to use.

On the POILoader form that allows you to select the source folder for the POI's you wish to load, it asks you "What units should be used for distance and speed?". Select "Feet and MPH" from the drop-down list and load your POI's again. All should be solved

Thanks guys, Sorted,
So it does not look like I can run a UK Speed Camera POI Database alongside a European one with correct speed warnings . Have I got that wrong ?

Hi Alex:

You are correct in your last comment, above.

There are two different issues involved in units of measurement for speed camera databases. One issue is what unit of measurement was used by the person who complied the database. The other issue is what unit of measurement you tell the loading application (POI loader) you want to use.

I purchase my speed camera databases from a German site. These folks have quite good coverage for both the UK and the Continent. In their database, they list speeds for the cameras on the continent in km/h, and speeds for the UK cameras in MPH. In other words a camera that triggers at 30 MPH (same velocity as 50 km/h) is listed as being a '50' if it is on the Continent, and a '30' if it is in the UK.

All well and good, but the GPSR can't cope with this - all the data imported in a given load has to be defined by the same unit of measure. This means that when I am on the ferry (or train in the Channel Tunnel) on the way to the Continent, I get to pull out my laptop and re-load the very same database I had previously loaded for UK use all over again - but this time specifying that the trigger speeds are in km/h, because I am going to the Continent.

If you are not sure about all this, create your own fake radar camera database by setting up two geographic points one block apart in the neighborhood that you live in. Set one to trigger at 30, and one to trigger at 50. Then, upload this huge database (both points) with POI loader set to MPH, and see how things behave. Later on, upload it with POI loader set to km/h and see how it behaves.

Actually, on second thought, it might be better for the sake of your driver licence and your wallet to try uploading the test database in km/h first, and then upload it in MPH second, unless you happen to live on a street with a 50 MPH speed limit...

Thanks Michael . Do you know if any enterprising individual has created a POI database that has converted European KPH limits into MPH ? Probably a long shot.

If you commute across the channel quite a bit, it could be worth your while to add a step to your POI loading workflow...

It would be a bit of work, but not too difficult to download the POI's ...

Then it looks like you can change the names of the *.csv files (SCDB info source) for the British (load them in a separate directory) speed cameras to km's (or work the other way and change the Euro ones)

If your Speed camera poi's are in GPX, it would be harder, but this URL talks a lot about the POI format, and what it does...

It looks like anything is possible... but only really worth it if you find yourself re-loading the poi's more than once a week IMHO...
