Hello,
 
How would you handle placing different POI or audio files on the same road, but designed for traveling out and back across the same road. We have a 20 mile drive to a "dead end" which is a to a beautiful overlook and would like to to play different POI audio files when traveling to and from this place. Is it possible to have POI that trigger off direction?

Unfortunately, Garmin devices do not support directional waypoints.  Thus, if the POI triggers when traveling the road the first time, it will also trigger again on the way back. 
 
If using a Garmin device, I have two suggestions:
  1. When a tour location is detected, the audio begins to play.  Instruct the user to mute or stop (it takes one click on a nuvi) the audio if they've already heard it.
  2. Though it would take some fine-tuning, you could position the POI at just the right distance away from the road so the user is within the set proximity when traveling the road one direction but out of the proximity when coming the opposite direction.  Assuming a two-lane road with 10ft wide lanes, you would put the location exactly 490 feet from the side of the road you want the audio to trigger (assuming a 500 ft proximity has been set).  Thus, when the user travels one way, they will be within the 500 feet, but won't be when going the other way.  Of course, this also assumes that you have good GPS accuracy when passing the point going both directions.  Like I said, it would take some fine-tuning, but I think it's possible.

If using GeoTours Mobile and GeoTours iQue, locations are played only once.  When you hear the audio the first time, the program remembers that the location has been visited and if passed again, it does not play.

Thanks, Scott

As I understand, with the new SDK garmin DOES support direction. Have not tested it yet though.

Yes it is.
Place the POI location on the right side in the direction you are traveling. Then set the proximity to only cover the lane or lanes for that direction.  There is an example in Kentucky, "Fort Knox Gold Depository" TourGuide, which uses 2 POIs, one for northbound traffic, which says the POI is on your "right side" and the southbound which says "left side". Foe each POI you have to associate a different VOICE.MP3 file.
 
Hope this helps....
 
Small 2 lane roads may be more difficult.

hdhannah - Thanks for the great working example of this concept!

I believe that the easiest way to handle this is to trick the device.
Or rather use the device's default setup against itself.
 
The device, or at least my ZUMO will continue to play a POI until the end of the file.  I will get a chime and the screen will tell me that I entered a new POI, but it won't stop playing the current POI.
 
Even if you enter a new POI's radius while one POI is playing, it will put that new POI in que to play immediately following the old POI.
 
However, (with my ZUMO)  If you are no longer inside the new POI's radius, my ZUMO will not play the next waypoint.
 
You need to create 2 slightly overlaping way points.  Point 1 going north activates and it recognizes point 2 as you enter the new POI's radius. But it doesn't activate because it is still playing point 1.  Point one needs to have an audio file that is longer than the time it takes you to drive thru point 2 so that when it is finished, you are no longer inside the radius of point 2.  At this point nothing should happen. And point 2 will be ignored by the unit.
 
Just work it in reverse for the opposite direction.  You could even use simple music or an inconsequential message to trick the device.
 
Hope this helps,
 
Ed

Ed,
Thanks for the great idea. We will test it here on a nuvi and see if it works.

Thanks again, Scott

Hi Scott,

Waiting on your report in reference to the overlapping circles.  Did you have an opportunity to test it on other devices?

Ed,
Sorry for the late reply. My wife had our second child in early December and due to some complications we ended up spending nearly 3 weeks in the hospital. Everyone is doing great now, but that obviously affected my time to test.

I have tested this on a Nuvi 750, and it works great! The only problem I ran into was the distance between the two locations. I ended up having to put them about half a city block apart. Otherwise, the opposite location might trigger before the one in the direction I was going. This is likely just due to the GPS accuracy. Putting them roughly 1/2 a city block apart seemed to do the trick, and as long as the audio on the track in the direction I was going was long enough to allow my car to pass through and beyond the opposite direction's proximity circle before stopping, it worked great.

Thanks for the great suggestion. I have only tested on a nuvi 750 so far, but I am assuming it will work the same way on all devices that support the Garmin TourGuide format.

Thanks again, Scott
