Stray proximity alerts

sgreenbank · Posted: Fri Aug 07, 2009 11:59 am Post subject: Stray proximity alerts

I have a Garmin 215T. I have the pocket gps speed cameras installed and a few other poi's.

What is odd and annoying is that the proximity alerts seem to go off for some of the non-speed camera POI's. (eg some of the petrol filling station)

I've never set these up, but it is the same POI's that repeated beep - there doesn't seem to be anything in the data on my PC to cause this problem and I always erase the old data with poiloader.

To be honest the whole POI setup seems to be way better on the TomTOM and that's comparing it to an ancient version running on a HTC phone.

From how I understand it, the warnings are based on numbers in the POI. I can't remember the name of the particular garage group off-hand but are these "extra" warnings for POIs that have a number in it.

This has happened for at least one supermarket and one railway station too - so its not just a particular garage group.

Do any of the POIs have numbers in the names or are they in folders with numbers in?

The word "mobile" will make it sound an alert for the T-Mobile one. Try T-Mob instead.

The others i'm not sure about.

also, if you have inadvertantly copied and pasted a file into the same folder in windows then it will default to the same file name but with '(1)' at th end - this will give a 1mph warning.

did it give a warning speed or just a warning? if just a warning then i would go with the 'mobile' thing mentioned above..!

I've renamed the t-mobile file and this it would seem has solved the stray warnings I also removed some of the othe POI's and this seems to have cured my jerky display too. see:
http://www.pocketgpsworld.com/modules.php?name=Forums&file=viewtopic&t=78475

I'm still getting far too many alerts for each camera typically 4 or 5 for 30mph Gatso and around 10 alerts for a mobile camera.

Can i ask what you renamed the t-mobile file too? I've never experienced a problem with the "-" character but the word Mobile (and GATSO, REDLIGHT and SPECs) will cause phantom alerts.

When you say you are getting too many alerts, are you still over the speed limit when you get these extra alerts? If so, then these are the Overspeed Alerts to warn you of your speed. Normally you get one low pitch alert as the Proximity Alert and a series of higher pitched, more rapid ones for the Overspeed Alert. The Overspeed Alerts will stop if you drop your speed below the speed limit.

The Mobile alerts will have more as the Mobile cameras have a longer range and therefore the alerts start earlier...

The file is now "tmobyle.csv". I think I read both messages and decide to implement both suggestions - it saved multiple attempts at getting it right.

The extra warnings are not over speed - unless I've slipped up and selected KM/H but the message has the correct speed which I believe means I chose the imperial option.

I am going to check them again this weekend.

OK I have tested it with a local 30mph gatso.

I get 5 seperate warnings (the last sometimes just after passing the camera).

I have deleted all my POI's and re-installed them. This made no difference.

I turned off the alerts to see if I was getting cyclops alerts. I wasn't as I received none.

I approached at 15mph and still got the 5 warnings.

I checked the camera number proximity entries on the PC and there are only 2 of them one for 133 and one for 266 (yards/metres?).

Not sure what else to try other than perhaps removing all POI's except the 1 camera and see what happens.

Whoops 199 & 399 the other values were from a 20mph camera.

In the gpx files on the PC which have xml coding there are 2 entries for each camera.

These are the proximity values from the gpx files for all the 30mph static cameras.

GPX files? Are you using Ash10s Camera Manager or are you downloading the Garmin GPX database?

You should be downloading the Garmin POILoader database from here which is in CSV format and contains NO proximity values.

Your csv into ash10 then to the Garmin using garmin poiloader

The gpx files are from ash10's utility.

I have no idea what format they take in the satnav so I haven't checked them.
