Hidden POI points

 

Help please. I am using a Nuvi 3580 to navigate in the North Cumberland WMA on an ATV. This is a mountainous area in East Tennessee with numerous ATV trails. I've downloaded and installed img files with fairly complete maps of that area. They show up just fine on my unit, track just fine, no problem there. My problem occurs when I try to plan a trip and want to mark the many turns I intend to make. These trails are like mazes in that some of the trails simply dead end in the middle of nowhere. I first tried creating way points at the turns I wished to make naming them in such a way that I would know how to turn. Good idea, but I found that when I got there, I could not see the way point on the screen, bummer. I could find it in the list of saved and even tell it to navigate to it. Only then would it show it. However in a day trip I might have many turns to make. SO I decided to go with the POI method. I set up test points within my POI files to see that they worked, with custom BMP markers, and alerts. My test around here proved successful, in that when I approached the markers, I saw it on-screen and got the alert I requested and the on-screen info if I tapped the marker. I thought I had it. I went out yesterday deep into the woods, and on my way, it found the POI's where turns needed to be made on the main roads. However, once I got on the trails, I never saw another single poi, not one, and I had about 12 turns to make. I had to rely on memory as to where to turn. I was in no danger, I had the trails on screen, just no POI markers. Can someone please tell me what's going on with that. BTW, my first turn to make was about 6 miles from the main road and none of them were any closer than that. I get the feeling that POIs somehow get associated with the main image file and won't display if you're not near one of them.

I could use some knowledgeable advise on how to use this unit to batter navigate off road.

where did the maps come from?

You stated you downloaded and installed maps of the area but where did the maps of the trails come from? Not all maps that display on a unit can be used for routing. I think this is the situation in your case. The image file is compatible but it isn't compatible with the routing engine.

Off-road.

Unfortunately, the nuvi and other automotive GPS devices are not very effective for off road navigation, although the newer nuvi's that have the version of Trip Planner that supports shaping points can work better than the older nuvi devices that don't have shaping points.

The motorcycle devices like the Garmin zumo and the handheld devices like the Oregon are capable of importing tracks that can more closely follow non-routable trail maps. No nuvi models can import tracks.

Installed Maps

The map came from GPSFileDepot and I know they are not routeable and I've accepted that. That's why I tried setting up POIs, if it's not routeable at least I could tell when I'm at a place I should make a turn. That's all I'm looking for. Why Can't I see my custom POIs?

Off road.

Like i said in the earlier post, the nuvi is not really designed for this type of navigation. Probably the best thing to try would be to set the navigation mode to Off road, then make a route (trip) using your waypoints/POI's for each turn as route via points. The route will show as strait lines between each of these points. Since the 3580 does not have shaping points, you will be limited in the number of via points you can have in each route.

Off Road

I'll try that now that I've finally located the route options under Apps. Sorry but I find that to be a ridiculous place to locate routes. Navigation seems a little more logical. I noticed that it was set for fasted time under navigation. I changed it to walking. Going on another outing on Saturday. I'll find out of that helps and I'll also do a rout with several way points and a couple of POIs. I'll definitely be off the grid. I'll also bring along my 76CSX to see how it handles routes and POIs.

Setting is for settings, not

Setting is for settings, not storage of routes and waypoints. Navigation defines the way you are going to be routed, not the actual routes.

It seems that no one is

It seems that no one is thinking about the OP’s actual question. He knew from the beginning that his map was not routable; he just wanted his custom POIs to be displayed to make it easier to do manual routing.

It looks to me that POIs are just a lat/lon coordinate that gets displayed on the screen. (Optionally you can get an alarm when you are “close”.) They seem to be near a route, not associated with a route. In fact that can be a really annoying issue when driving on an interstate that goes though some towns – all the local red light cameras keep alarming even though they are not associated with my route.

Seems like the OP has loaded and pre-confirmed his custom POIs. Yet when he actually gets close to them they seem to not be there. Since under more typical use without navigation all POIs show up, what is special about his case that hides POIs.

Zoom in closer

I have your zoom in closers to see my customers POIS on my Novi 2450.

Hidden pois

Thank you for actually reading my post. I don't think it was that hard to understand but in the age of speed scanners, lots of folk don't really pay attention to details, you are an exception. Thank you. I have tried everything under the sun to get them to display with no luck. If these are place near a routeable street, highway, road, whatever, they appear nicely. otherwise, forget it. I pulled out my 76CSx and while they are displayed but I have a new issue there, other than saying approaching SW132, it will not give any more information. I can of course go through the menu structure and find the waypoint and see what that says, but i'd really like it to display more info on the point I'm approaching. I tried using the geocache feature, but it has issues of it's own. I wish there was a table mapping app that would read img files. Any suggestions out there?

My way

Let me set myselfe straight.
You want to ATV a trail and the Garmin tell you where to turn at intersections but your Garmin is not telling you this properly.
After thinking about this I think the best way and one that can be used over and over is to make your trips as TourGuide routes.
First I would make MP3/WAVE files of every turn such as "turn Left at intersection and on the way back turn right TourGuide" or "Turn right at intersectionand on the way back turn left TourGuide". I would label them as "Turn right at intersectionand on the way back turn left Tourguide" or other turns. Then I would go to the map and at each turn intersection get the coordinates and at that place draw a circle of how early you want the notifications. The way you plan this is your choice but I would have a folder in my Garmin files Labeled ATV trips and after loading it on the Garmin I would put .old after the gpx file so that I could use the MP3/wav files for a new TourGuide.

i wonder

I wonder if the display of POI or routing markers in your case are tied to the routing engine. You are driving (riding) a route between points. If you try to set up your Nuvi where it goes from the trail start to the first marker and then the next, you are building a route. If you are just trying to put a marker on a point and then follow the trail shown without telling the GPS to route there, then it may be related to the map in that the Nuvi doesn't have a way to interface with the map and display the point.

maps may not interface with the base map

I agree with Box Car. While I am not a "trail" expert, in my opinion the maps are not interfacing with the base map already in the nuvi. You don't care whether the maps are routeable, but if they were routeable, I think the waypoints could be seen.

The maps are the key to solving this problem. Is map tech support available? Perhaps they could tell you whether the nuvi 3850 can use these maps, or whether a trail GPS can use them.

Agree with kurzemnieks

I strongly urge trying the TourGuide technique - noting that it does not rely on "routing"

Routeable Free Whole World : http://garmin.openstreetmap.nl/

these are routable, I have 500miles around my home in NS, including every woods trail. ( Ithink, havent been lost yet )
But you can just select 1 tile between la Follete and Big South
