Newbie to Garmin 760 needs help grasping some POI concepts

 

Hi all!

I'm not new to NAV units but I am new to the Garmin 760.

I need help understand the POI process and how it works. While my questions may not be totally Mac oriented I thought I'd start here amongst my Mac friends.

I have downloaded virtually all of the Mac apps for the Garmin 760. I successfully downloaded and converted a POI .csv file which I successful converted through the Mac version of POI Loader. I put the files on the root directory of an 8GB SDHC Card that I purchased. I then went to Where to>Points of Interest and can see my downloaded POI and call it up. Fine so far.

As a good MacFanBoy I then brought down the following files: Apple_Store_V.csv, Apple_Store.bmp, Apple_Store_ahead.mp3. I used POI Uploader to do its thing and put the results on the root directory of my SDHC card. I read that I should put all files of the same name together in one location or folder. (If I made a separate folder for Apple Store would the Garmin see the files?)

Now when I go to Where to>Extras I find all the Apple Store POIs. Again, good so far. My questions are:

- Will the .bmp image appear on my Garmin maps during my journey?
- Will the .mp3 sound "Approaching Apple Store" be spoken automatically?
- When does the .mp3 sound play? That is, how close to an actual store do I need to be to hear it.

Any tips on files structure on the SDHC card would be appreciated as well.

Thanks, in advance, for any tips, suggestions, tricks, etc.!

not familiar with apple, but

under the usual conditions:
1. bmp should appear
2. sound should be spoken
3. when you run the poi_loader you need to do it manually and then you can set the distance for the sound to play.

One thing I learned from people on this site is build windows directories for different poi's, and they showed it being done like the following:
--Restaurants
with your_poi_1.csv, bmp, mp3
--Road
national_parks.csv, bmp,mp3

You can have as many csv files underneath each directory, than they will appear on your gps with the directory name and each poi file below it.

Just play around with it, and find the best way for yourself. Like I say, I am not familiar with apple, but I hope this helps you. good luck.

Zoom level...

Zoom level will play a factor in visibility of POI icons. You need to be zoomed in (to at least the 300' scale) for your icons to show on the map. Of course, if you are routing to a POI location, you should see that as you reach your destination.

As noahjokc said, you can set the proximity alert if you run POILoader in manual mode. You may want to think about audible alerts on something like an Apple Store - unless you are going to one, you may not want that sound to pop up every time you get near one. It's probably not bad with something like that, but if you load a bunch of POI files, and have them all alerting you, it can get pretty noisy in the car smile The only audible alerts I usually turn on are for red light cameras and school zones (I have speed camera on also, but there aren't any in my usual driving areas).

POI concepts

As others have pointed out, the user-created POIs are under Where To > Extras > Custom POI. You can have the POI files anywhere on the GPS, main memory or an SD card, and the OS will find them. Same for JPG's and MP3's.

If you load the POI, a bmp and a mp3 at the same time, the bmp will show on your screen as you approach the position of the POI. However the mp3 will NOT play unless you have a proximity alert set. Garmin is funny about proximity alerts on CSV files, it doesn't handle them quite like you would expect but the mp3 will play at the distance you have in the proximity alert.

As for the directory structure on SDHC cards, it seems to be basically a windows structure with directories and sub-directories. There is a limit to the maximum number of entries you can have in the root directory however that limit disappears if you place them in a sub-directory.

As for placing POIs in their own directory. Some folks like to rename the file name, keeping the same extension with all the POIs in the same directory. Others, like myself, like to place them in their own directory and leave the file name alone. It seems to be 6 of one and half-dozen of the other.

What files did you place in the root directory of the card? POI Loader should automatically place the gpi file that it creates into the \Garmin\POI folder. I'm unfamiliar with a WhereTo>Points of Interest option (not on 660), but are you sure that isn't the built-in POIs; seems strange you can see custom POIs under both Extras and Points of Interest.

I then brought down the following files: Apple_Store_V.csv, Apple_Store.bmp, Apple_Store_ahead.mp3.

These 3 files must have the exact same name except for the extensions. I would recommend you organize them on your computer as recommended by Motorcycle Moma:

Folders/files on your computer --

> My POI (Main folder)
>> IHOP (subfolder)
... IHOP.csv
... IHOP.bmp
>> National Parks (subfolder)
... National Parks.gpx
... National Monuments.gpx
... National Recreation areas.gpx
... National Parks.bmp
... National Monuments.bmp
etc.

In this example, IHOP and National Parks show up as categories and then under National Parks, the subcategories of National Parks, National Monuments, and National Recreation Areas show up.

Here are some screenshots of what it would look like.

This is a shot of the folder and files on my computer.
http://i18.tinypic.com/4q8bl8m.jpg

This is how the first level shows up on my Zumo.
http://i9.tinypic.com/4t6c8ye.jpg

When I select the National Parks category, this is what I get.

Then if I select National Monuments, I get this.

POI icons will show up on your route if you are zoomed in far enough and some models require that you be in 2D mode.

POIs do not automatically alert. You must set an alert -- usually by running POI Loader in "Manual" rather than "Express" mode. You set the distance at which you want to be alerted within POI Loader in Manual mode.

Until you are more comfortable with POIs, I would suggest creating no structure on the card -- let POI Loader place a single gpi file where it belongs. All categories are built into the single gpi file according the structure you established on your computer.

Wow!

Folks I'm overwhelmed by the quick and thorough responses! Thank each of you for your input.

I'm going to re-read your comments tomorrow and tinker with the Garmin and how my SDHC Card is set up. I understand many of the Garmin's features intuitively but so many rich resources are available that I am bowled over by the possibilities and the feature sets.

If I need more help I'll certainly come here for sure.

Thanks a lot!

More for Bentbiker

Hello bentbiker - and the others who have been helping me out too!

bentbiker, I'm having trouble wrapping my head around a few concepts.

Let's say I download a .csv of POIs in, say, Boston one day from this site. I use the POI Loader on my Mac, put the .csv file in a folder on my Mac and let the POI Loader create the .gpi file. Right so far? Now, the next day, I want to add some additional POIs and go through the same process as above. Does POI Loader take the new data and merge it with the existing Boston data resulting in only ONE now larger .gpi file? Or am I supposed to see individual files with .gpi extensions?

I did take your advice, with two exceptions. (I wasn't sure that the Garmin could "see" inside folders (directories) so, for my SDHC card, I created a Garmin>POIs folder. I have now trashed that. I only have two directories now on the Card - "JPEG" and "MP3s" - is that OK? I'll let POI Loader put its results on the root directory of the Card. OK?

Now, on another issue. When I initially installed/converted my first POI on the Card, I temporarily created a folder on my Desktop "Untitled" and put the .csv in that folder. Subsequently when I read your input and others here, I created a permanent file on the Mac called "My Garmin POIs." I took the Apple POI parts, made sure that the files names (except for extensions!) were identical and put a .csv, a .bmp, and an .mp3 inside. From POI Loader, I have the path to "My Garmin POIs" selected. I selected "Manual" and checked "This file contains proximity alert points" then clicked on "Alert whenver you get close to a point" and input 5000 ft and hit "Continue". The POI Uploader created a folder on the Card that reads Garmen>POI>POI.GPI so I think that phase is OK. (BTW, How do I know if a particular POI contains proximity alert points? The Apple Store POI is the example I'm using but I don't know what is built into it.

Thanks noahjokc, Moose135, jackj180, bentbiker

I think I'm on the right path but many more questions might occur to me on this, ah, "journey." Thanks for sharing you knowledge folks!

When you run POILoader, you should upload all your POI files each time (there are ways around this, but I'll keep it simple for now). POILoader will combine all these individual csv or gpx files into the one POI.gpi file on your Nuvi. If you only upload the new file, the current file on your GPS will be overwritten.

If you place the individual POI files in separate subdirectories on your computer (and point POILoader at the parent directory containing these subdirectories), you will see different categories when you go through the Extras menu, with the individual POI files listed under each category.

Neither. Every time you run POI Loader, it creates a file named POI.gpi and puts it in the same folder -- \Garmin\POI. If a previously loaded file is there, it is overwritten. Thus, the easiest solution is to reload every file each time; this is done by pointing to the main folder on the computer, with the various files in subfolders. This structure creates categories within the POI.gpi file that is loaded onto the gps. There are multiple alternatives that you can use down the road, but it will only confuse you now, and most people never change from this procedure.

As far as I know, none of the files here have proximity alerts built in. A csv file has no provision for such alerts. You can test your alerts by simulating a trip past the location -- you don't have to drive the route. Also, if you choose a specific custom-POI location by going to Extras/Custom-POIs and click on it, it will advise you of any alerts if they are loaded.

Thanks bentbiker

I see that Moose135 had addressed some of the POI/.gpi files issues bentbiker now that I re-read what he posted.

Your current reply/explanation makes things much clearer now as I was not sure how things were read. The one file, entire structure makes sense now as do your pointer about returning to the main folder to generate a new/replacement .gpi. Thanks!

And you must be clairvoyant bentbiker because I was just wondering if I could test a .gpi file through simulation and there you were anticipating me next question.

Great!

Thanks again,
SNazz123

More questions

Here are a few more questions that have occurred to me that I could use some help with please.

First - Let's say I want to take a roadtrip from home to a destination and back home again. I have, right now, 2999 POIs including the Apple Store Locations, Offbeat Tourist Attractions, Speedtraps, etc. Now let's say I have my trip destinations all set and am ready to start my trips. Must I got to Extras/Custom-POIs and individually and manually select them for them to alert me or do they alert me (based on the parameters I included through POI Loader). My goal is to have all the POIs alerting me together not to select, Apple Stores now, Offbeat Tourist attractions secondly, etc.

Second - I tried simulating a trip as suggested by bentbiker to see if my Apple alerts/logo/sounds would trigger. The simulation mode, however, was in real time and was tedious and I just quit the process. Is there someway to do the sim, see if my Custom POIs are working but make it speedier?

Again, thanks in advance everyone!

Alerts do not need activation -- they alert according to your original parameters.

To speed up the simulation, set your location close to the test point, pick a destination well past the test point, and allow the simulation to take you past it. To set your location, tap the map to put it into browse mode, drag the screen to the desired area. Tap the screen to place the arrow where you want your virtual location, and hit the Set Loc button at the bottom. Then pick destination point by same method, except don't hit the Set Loc button -- hit Go.

You can't really set proximity alerts with CSV files. You can set location alerts with the proximity alert varying according to your speed. Faster speed = longer distance. You do this by including the keyword "Redlight" (without the quotes) in the file name. This will play either the bing-bing-bing or the mp3 you load with the POI file. An example would be a file named "Apple Retail Stores Redlight"

You can also set a speed alert on a CSV file by including the "@" symbol followed by the speed in the file name. An example would be a file named "Apple Retail Stores @20mph". This would sound the bing-bing-bing if you were going over 20 mph but not under.

These examples only affect the audible alerts. The icon will display on the map whenever you get within range of the POI if you have the zoom set close enough.

You do not have to activate or turn on POIs. They will be active at all times.

One thing I feel I should point out, CSV files are easy to read and write and are small. But they are limited in the information they can contain and display. I use GPX files for the POIs that I write. You can set the proximity and speed alerts independently for each entry. You can have a proximity alert without a speed alert for one entry and just the opposite for the next entry. You can also enter addresses, phone numbers, meeting dates and times, etc. The files are much larger and you will have to have something more than a text editor to write them (I use GeePeeEx).

As for sims, yeah they're slow. You could set your location close to your POI and then start the sim but it will still be in real time.

Thanks bentbiker and Jackj180

Gents - I appreciate your help! As an experiment I took the nuvi 760 out in a car that I have that has a built-in NAV unit and had my wife explore the 760 whilst we were in motion. Just as you both said, one of our POIs alerted and gave us an icon on the display. Great! And a modest start for me.

Looks like there are a ton of tips and tricks available. Thanks for yours Jack j.
Hmmm. Should I be seeking out GPX files instead of CSVs it they are available and contain more info tucked inside? Is the POI Loader used to work with those files too?

The GPX files MAY contain more information but it is not a given. Many GPX files are built from the CSV file so the data is the same.

a_user is right, a lot of GPX files are created from CSV files. If the author doesn't add info when he proofs the GPX file, it won't contain any more info that the original. Plus, quite a few POIs really don't need much info past the coordinates and a name to set the entry apart from the other entries. A good example would be the files with railroad crossings listed. You really don't need the added versatility of GPX with them, all you would gain would be a larger file. But a file that listed all the auto museums in the USofA would need info like hours of operation, seasonal days of the week, phone numbers, mailing addresses, prices, etc. That info could be put into a CSV file but it would be very hard to access using just the GPS.

Decide what info you need and what info would be nice to have in the file and then decide which of the two formats would best fit your needs.

Sullivan's Law: Murphy was an optimist!

Thanks JackJ, a_user, and Tailspin

I'm very impressed at the help I've received from each of you and all the others including bentbiker here. Wow! I'm a pretty quick study with technology but I'm seeing that the GPS devices (and related software) are like like onions - there are many layers involved. Even before I got the Garmin nuvi 760 I started pulling down as many Garmin apps for Macintosh: The Garmin MapInstall, the Garmin MapManager, the Garmin RoadTrip (formerly "Bobcat"), the Garmin POI Loader, the Garmin WebUpdater to try and get the lay of the land. Of course, certain apps would only activate once I actually received the GPS unit and connected via UPS.

Jack - Thanks for confirming that sims are slow and jumping ahead to a point as several folks have said can help. I also can see the pro and cons of CSV and GPX files now. I also see that I was confusing proximity alerts with location alerts. I'm not entirely sure of the differences but at least I understand that I was using the wrong term. I did see the proximity alert relative to speed in the POI Loader and that's interesting for the speedtrap POIs.

Tailspin - it is great to see a knowledgeable Mac user here using the same OS as me. I'm looking forward to digging into this more and will check out the link you provided.

For today, I have just two quick questions if you'll indulge me:

1) My wife and I were thinking of taking a roadtrip from NH to PA and back home to NH in May. Is it better, in general, to try to create our roadtrip via the Garmin unit itself or should I use one of the Garmin apps such as RoadTrip if we want a lot of stops along the way?

2) I noticed that the Garmin 760 has three options: Fastest Time, Shortest Distance and Offroad. I would like to use interstate highways for part of the way and use secondary roads (but not offroad) for part of the trip but mostly secondary roads for sightseeing purposes. Fastest Time, Shortest Distance and Offroad don't really fit the bill for what I want to do. As part of this question: Can I force our directions by simply adding waypoints to a route I'm creating? I guess this is very much a chicken and egg thing and I don't know what to do to start the process or (see question one) if I should start on the computer or the GPS unit itself.

Thanks again all!

Trip planning and determining a route is a process and, as you are learning, can be quite involved. I normally use mapping software to plan my routes as it is much easier to manipulate routes and plan stops. As the GPS is a device to mainly direct you from point A to B, it doesn't function too well as a planning tool. Plan your trip using some of the tools rather than trying to do it on the GPS.

Limiting yourself to the three choices in the GPS will only bring you frustration. Use the trip planning tools and create the waypoints. If you truly want to get creative, read up on what a TourGuide can do for you and play with it. This is a GPX style file, but you can have it route you through the waypoints you want for the journey. Playing with a TourGuide and creating one requires some knowledge of HTML programming, but there are some examples of complete tour guides available for free download that provide the format and how to link waypoints into a route. If you don't want to go that route, then create the route with the starting and ending points and feed it the waypoints to shape the route on the roads you want to travel.

Above all, have fun on the trip, keep a paper map available, and review the day's route before starting out. This will help you in case of unforeseeable changes that always seem to crop up.

Personally, as an old gray-haired guy I rely more on the paper map to get an overview of where I'm heading and use the GPS to monitor my position and alert me to points of interest as I travel.

Hello and thanks for the further followup. It's an obvious tip: Don't leave the paper maps behind (!) but one that is an invaluable thing to say! We always like to have a "Plan B" for a backup. Thanks, too, for sharing how you use the GPS and how you use the paper maps. That makes a lot of sense. Sometimes "old school" is the best method!

I appreciate the suggestions re: mapping out a route with stops. I can see that things can get pretty complex very quickly. Perhaps, as you suggest, having a starting and ending point (both "home" if we do this as a roundtrip) and adding "via" points (to select secondary roads when desired) and "waypoints" would be great. Determining POIs along the way will be a challenge too.

Thanks again a_user!

Answer and a new question

I selected the folder and uploaded that - it seemed to work.

Now, I had several sound files in the folder as well. These seemed to have been uploaded as well. So far, so good. The sound files were basically associated with the same POI - can I select one? Will they both 'sound off' - if so, can I erase one?

The only sound file (.mp3 or .wav, depending on your nuvi model) that ever "sounds off" as far as a POI is concerned is one that is named exactly the same as the POI file, except that the file extension is .mp3 or .wav . So if you have other files that do not fit that naming convention, they would be the ones to delete or move.

If you are using both .wav and .mp3 file, remove the .wav if your unit supports mp3 playback abd you wamt to use the mp3, otherwise remove the .mp3 version if your unit does not support mp3 or if you want to avoid the problem of skipping to the next song after an alert is played.

Using WAV with an MP3 compatible

Coming from a 200 I have most of my alert sounds as WAV files. It was a riot trying to listen to "Gertrude" tell me to "turn right on Main St." while getting "Approaching a Red Light Camera" being played as a WAV alert over the top of the turn instruction.
