Speed trap alert sometimes only seems to work in one direction

 

Noticed some odd behavior from our 265W (as well as other drivers) driving to/from Baltimore on 295. There are a couple of known revenue enforcement hangouts near 695 that the unit reports as you approach when you're heading North into Baltimore, but when you're headed South coming home, it doesn't alert.

The alerts are set for around 2000 feet, so I'm not sure why this is. Do POI files contain enough info to only alert on a particular direction?

It may be a POI file problem since it didn't come from here, but I'd like to confirm that could be the case and not a problem with our Nuvi.

It could just be that the POI file is actually a POS file... smile

That's because the Baltimore-Washington Parkway is wide and the Custom POI you have is on the Northbound lane. If there is a hangout around the same area but for the Southbound lane, you will need another Custom POI which will have a little different coordinates.

There is a way around this by using one Custom POI and place it in the median and use the word 'TourGuide' in the file name. You would set an alert distance with POI Loader in the Manual Mode. Oft times ~2600 feet is enough.

There has been much written about it here. In addition you may want to refer to my article:

THE 'PROXEMICS' OF THE TourGuide -

on Custom POI Page 4

See where the marker is

Try using something like itouchmap or Extra_POI_Editor to see where the marker for the sites are. It's possible they are on one side of the road that would put them more than the 50-75 feet from the other travel lanes.

That makes sense, I thought that it must be capable of handling the two directions separately. Thanks for the great info!
