You cannot load tracks  on Garmin's automotive devices, this has always been the case and is a common complaint. So I assume that your "maps" are actually tracks, and those just won't ever work. You can load gpx files with waypoints, but not tracks. To clarify: gpx files can contain either lines or points. Lines are called "tracks" and points are called "waypoints". There are also "routes", but on a Garmin Automotive Device, these will be converted to "trips".

Apparently Garmin has done this intentionally, because there's no technical reason why it shouldn't work. But Garmin has always had a strategy of removing certain features from devices to force you to buy something more expensive. In this case, they want you to buy an outdoor-type device if you need to use tracks.

Now there is a work-around, but not very simple. You can use one of these programs to turn your tracks into transparent maps that will display on top of the City Navigator map. The first one is free, I have not used either.

What is Caltopo? Is it a Garmin map? If so, then can't you just open the track in Basecamp, take a screenshot and save it as a PNG file?

One of the maps I have been working with is Montana State on the gspfiledepot website.
Every time that I tried to unzip the file I would get errors.

Is this the map?

If so, then it really doesn't have anything to do with GPSFileDepot. You did not download this map from GPSFileDepot, it is hosted on another website so any problems you had were from http://www.miscjunk.org/mj/mp_mttopo.html

Using The Maps/Garmin Software / Re: gmapsupp file in etrex 20
« on: February 28, 2020, 05:33:23 PM »
I don't understand how you created the gmapsupp.img file. The "old way" to do this with Mapsource is described here: https://www.gpsfiledepot.com/tutorials/how-to-load-maps-on-my-garmin-gps-unit/#mapsource

However, the eTrex 20 isn't one of the old GPS units that can only use a single gmapsupp.img file. The eTrex 20 will recognize map files with any name as long as they have an .img extension. On this type of device, it is better to use just one map per file. My experience is that when you combine multiple maps in a single file, there can be issues, especially if the maps are from different sources/authors.

The " disk image is corrupted " message is bogus and doesn't mean anything. Garmin maps have an .img file extension, and (unfortunately) the .img extension is also used for disk images. The computer doesn't find the right kind of data and therefore assumes you have a courrpted disk image. But in fact you have a valid map file.

What maps did you download? How did you install them? Most of the maps on this site include an installer that will put the maps into Basecamp on your computer. You should then be able to view them on the computer and make sure everything looks OK. You then use MapInstall to send the map to your GPS. Did you do all of this?

There is an older version of Basecamp/MapInstall that doesn't work correctly. Make sure you have installed the newest versions.

Another possible problem is the way the SD card is formatted. It must be formatted as FAT-32 and this may not be possible with cards larger than 32gb (IIRC). If the card is not formatted FAT-32, then everything will appear to work on the computer, but the GPS will not recognize the maps.

Might have something to do with the Windows registry. Have you seen this post from 93ToyTruck?

As for "whats going on"... Basecamp is a mess and Garmin got tired of trying to fix it, so they have abandoned it and moved on to a web-based program that supports their new, premium devices.  ;)

Not sure what would be gained by waiting. Basecamp has been discontinued and Garmin isn't going to be improving it. We were all surprised when they actually fixed the map installation bug. But it took a year and a half before they did that.

Why do you have to wait for a couple weeks? You can look at different place on the GPS without actually being there. And you can turn on the GPS simulator in the menu so it will act like you really are there.

First, these are not "disc image files". I know that's what your computer says, but it's wrong. ;) They are Garmin map files. The problem is that the .img extension is used for different kinds of files.

A little hard to tell, but what you describe sounds OK. I assume you can you view the map(s) in Basecamp/Mapsource on your computer? See this tutorial for map installation. Unfortunately, it's a little out of date.

 https://www.gpsfiledepot.com/tutorials/how-to-load-maps-on-my-garmin-gps-unit/

Anyway, there shouldn't be a problem using topo maps on a Nuvi. Sometimes, they don't look very good, but they work. So - sorry - you must be doing something wrong.

What is the "predecessor of this site"? GPSFileDepot has been around for quite some time.... I have been posting maps here since 2008, and it was not new then. :) But anyway, it's meaningless to talk about the "maps from this site" as though they had something in common. They do not. This site is just a collection of maps by many different people. There are no standards for how they are made and there can be big differences in the approach and method. of the authors. In other words, it's like talking about the "books from the library", as though they all had something in common.

Most of the maps here should work on a Nuvi. If you are having problems with all of them, then you must be doing something wrong (or you're incredibly unlucky in choosing maps that have problems).

I spent a fair effort to make my own maps look good on a Nuvi. They may not cover an area you want, but they definitely work on the Nuvi - try this as a test: https://www.gpsfiledepot.com/maps/view/785/

Are you saying that you have an SD card where your old maps work but new ones installed at the same time don't? That would be odd. How many maps total do you have on the card? Where are they installed? Newer Nuvis like yours expect the map to be installed in a folder named Map. If the card is in a computer slot or USB reader (instead of inserted in the GPS) when you install the map, then Garmin's software may not do this correctly.

Also, with Mapsource, when you install a new map, it will erase an old map on the card because it always uses the filename gmapsupp.img. MapInstall shouldn't do that. You can also manually re-name gmapsupp.img to something else, like topo.img after installing.

If you don't format the card as FAT-32, then it will not work in the GPS. How big is the card? Cards larger than 32gb will not work properly.

Also, are you sure you have the newest version of Basecamp? Because the version before that was broken an could NOT install most of the maps from this site.

Just some ideas. No idea what's wrong, but almost all the maps here should work on your GPS.

General Discussion / Re: Why has a map of the entire US not been made?
« on: February 06, 2020, 08:46:36 AM »
Well, sorry, my memory was wrong on that point. It actually had a lot more - total of 6633 segments in Topo 2008! I had this version and an older version from around 2004? Then I have two new versions with the small segment count (about 500) that were pre-loaded on my Oregon 400t and DriveTrack 71. See this old article:

http://www.gpsinformation.net/waas/maps/topo2008.html

"The 2008 topo maps have a total of 6633 segments."

It's my opinion that large files aren't a problem in and of themselves. But in my case, these are unique maps you can't find anywhere else, so if somebody wants them, they have no choice. And my target is mostly smartphone app users, not Garmin owners. People using dedicated Garmin handhelds might be a little more.... old fashioned?  ;D

All I can say is that nobody has yet complained about file sizes. My maps load into Mobile Atlas Creator where users can send smaller portions to either a GPS or phone (like MapInstall).

Maybe I don't understand what you're saying Popej? As mentioned above, Garmin's old 100k US Topo had about 4500 tiles in a single mapset. It was originally distributed on multiple CD's, and later they switched to one DVD.

That is very interesting about MapInstall splitting files automatically. Didn't know it could do that!

Regarding large files, I disagree. I make big multi-level raster maps at very high resolution. They are specialized maps that only cover the small region where I live in Southern New Jersey. These are all big files and the two most popular are 15gb and 12gb with lots of downloads. https://boydsmaps.com

So IMO, if the map is something that people want, large files are not a problem (at least here in the US).

Good find!  8) I knew this was true with waypoints on automotive devices, and has been a complaint for a long time. Didn't realize it was also the case with handhelds. They really should give you a choice of sorting. And their iPhone app "StreetPilot" actually had that option, which I really liked. But Garmin killed that app, I guess they felt it was hurting sales of their dedicated devices.  >:(

Most of the files here should work on a Nuvi 760 but they are not capable of creating routes or providing turn-by-turn directions. They can only show your location on the map. For automotive routing, have a look at OpenStreetMap: http://garmin.openstreetmap.nl
