POI alert distance?

[biogoo]

I loaded the Pocket GPS World speed camera POIs onto my MY14 XC60's nav system, and gave it a try this morning. The alerts trigger when I'm nearly on top of a camera, which makes them of little practical use. Does anyone know of a way to change the alerting distance? My previous cars have all either defaulted to a decent distance, e.g. 2 or 3 hundred yards, or have an option to change the alert distance. I can't find anything similar in the Sensus menus though. Or perhaps the GPX files can be adapted to include an alert distance?

I'd also like to reduce the alert volume, but I again can't find an option for this. Does it just use the "phone ring" volume setting?

I also find it sets off an alert if there's a camera on the other side oR on a road nearby...pretty basic.

Having used the above for many years now there is no way you can adjust the distance alert, but the volume can be changed in the same way as Traffic Alerts, etc. Just lower the volume as it sounds which will be remember next time.

When I am in an area which I expect to have camera's etc, I keep the Sat Nav map open at an appropriate scale so I can see the camera's in advance.........

So, I'm answering my own question in case anyone else is interested. I've found how to do this with a little online research.

The proximity alert distance can be configured, on an individual POI basis, by extending the XML in the GPX file with a gpxx:Proximity element. I've scripted the addition of the proximity element for every camera in each file from the PGPSW download using different distances based on the speed limit associated with each camera, and it definitely now alerts much earlier. The value is supposed to be expressed as a number of metres, but this doesn't seem to align with when my alert sounds, so there's more fiddling to be done.

As for the alert volume, it uses the setting of the voice notification volume so you can't have different levels for these.

How long did it take you to do this I would also like more notice, at the moment, it is pretty useless.

Would you be able to share your method of tweaking? I would love to do the same thing to my downloads too - I have put it up with it being too late notice for a year now!

I just wrote a Python script to iterate through the waypoints within each PGPSW GPX file and insert a gpxx:Proximity element with a value based on the speed associated with each waypoint. I've tried various multipliers for this value and haven't quite got it right yet - it's supposed to represent metres from the camera, but doesn't seem to be that in reality.

Having dug around a bit more, apparently "Ash10's Speed Camera Manager" can be used to accomplish this and more - see >linky<. I don't use Windows, so haven't tried it myself.
