Proximity alerts – again???
 16 years
|
I am relatively new to a Nuvi205W but I have been Geocaching for years with a Magellan Explorist 500. At any rate I recently made my first driving trip with the nuvi. Before going I wanted to load rest area POI. Did some reading on this site on how to use POI loader and I jumped in to load the Illinois and Iowa CSV files for rest areas. I used the manual method with a proximity alert at 10000 feet. We passed six or eight rest areas but the proximity alert never went off. On a couple of rest areas we actually stopped at the alert went off after we were inside the rest area. Any thoughts as to what I may have done wrong?
Also was reading some threads here (about a year old I think) that had differing opinions as to whether one needs to be on the same road as the POI or have a route set for the alerts to work. Don’t think that applies to my problem but did make me curious.
Which
Which rest area file did you use?

I used the separate CSV
I used the separate CSV files for Illinois and Iowa. I did not use the big one for the whole USA. I assumed (perhaps my mistake) that the smaller files would be similar data to the big one and I didn't need to whole country.
The location information is not the same
If you look at the coordinates in the separate state files you will probably find they are on the building or at least the parking lot for the facility. These normally are too far from the road to trigger the unit. In normal instances, the location must be within 50-75 feet of the route of travel to generate an alert. The combined file has the location coordinates at the off-ramp from the road into the facility which is why they always work.

Sometimes They Aren't There
I have used the combined files and it does a pretty good job of notifying you. I have had a few times that it doesn't alert you. Rest Areas for a lot of the Secondary roads aren't in there, but all of the Interstate ones should be.
You should be able to look at the file and see if the rest area is in there. You could also the "Extra Poi Editor" that is available on this site to see what is in the file.
If you saved the location, you can send the location to maintainer of the Iowa and Illinois file, or you could add it yourself.
I usually set my alert for rest areas at 5200 feet, but have set some of them to 10400 an they work fine.
The reason for the late alert is probably due to a difference in your nuvi and the lat/long that was entered. If you saved it, you can send it in to be modified.
good luck
