Garmin needs to fix this, it's a disgrace. It has been almost a year since they broke MapInstall.

My understanding is that the "GPS Software" is the low level firmware for the GPS chipset itself. I don't know why that would affect anything in a map, but it's possible. No experience with creating locked maps.

What is a "key generator"? That sounds like the kind of hacker tool that some people have used to illegally crack Garmin's maps. If so, then the management of this site would not approve of any discussion.

OK, I see. But still don't understand the part about different data for devices with different serial numbers. Is that just because you customize the data depending on who you give the unit to? I don't see how GPS firmware version would have any effect on that.

If you just want to try different firmware, it is all archived on this website. IIRC, with an old device like yours, you would change the name of the downloaded firmware file to GUPDATE.GCD and place it in the \Garmin folder on the GPS. When you restart the device, it should ask if you want to install older firmware if a newer version is already installed.

Not sure how this would help you though. Or do you want to install firmware from a completely different device on your Nuvi? Garmin certainly doesn't want you to do that and I don't think it is easy. People used to discuss this kind of thing in the GPSPassion Nuvi forum. But those days are long gone, there is very little interest in the whole field of dedicated automotive GPS anymore, let alone advanced topics like firmware hacking.

I can't help with your specific question, but the Nuvi 750 was introduced in 2007. Would be surprised if Garmin made much effort to support a 12 year old device.

And I don't quite understand this part

"I compile personal data into a gmapsupp.img file to use around where I live"

What kind of maps are you making?

"I've went through my personal data files to make sure all the units have data that's been specifically matched to their serial numbers"

The only maps that are tied to a specific GPS device are Garmin products such as City Navigator (or possibly some commercial 3rd party maps). The April 6th issue should not be affecting any of this, unless it triggers some other strange Garmin firmware bug.

Have you tried contacting Garmin support? I wouldn't hold out much hope for a solution, but it would be interesting to see what they say.

Perhaps Birdseye imagery (if you have a Garmin GPS)? You get recent aerial photography that will be more current than most maps. Costs $30/yr from Garmin. But you get unlimited downloads and you can continue using what you have saved after the subscription expires.

This model, and others from the past 3 or 4 years, displays them as ugly big "hearts" with no labels

Didn't realize this until I went on a long trip the other day, but they have changed the appearance of POI and waypoints on the DriveTrack 71. The icons are much smaller and they look a lot nicer. I wonder if they also made this change on the DriveSmart 65?

I should also add.... after you have copied the GUPDATE.GCD file to the device and safely removed it from your computer, it is recommended that you connect the device to an external power supply. If it shuts down during the update process (from a low battery, for example) it could permanently "brick" it.

And also realize that there's always an element of risk when you mess with this kind of thing, so don't do it if you are concerned. Many people (including me) have downgraded firmware with no problems whatsoever, but "caveat emptor". :)

I explained how to roll back the firmware in great detail in my earlier post, please read it again. Impossible to say what version was originally installed on your device, since it could have been sitting in the box for a long time. But yes, you need a version from before when you purchased.

As I said, mine is running version 3.40 and apparently it does what you want and I haven't had any problems, so you might try that for starters.That would be this version

« on: March 21, 2019, 03:51:54 PM »
I have never messed with .typ files for City Navigator, but have used them extensively in my own maps, and even written software to manipulate them. Are you talking about the link I posted to the typwiz 5 software? I had an older version of that package, and the documentation was quite good. I believe he provides some templates for creating a .typ file from scratch. But a .typ file does not need to contain a definition for every kind of object. If you only want to change the appearance of railroads, then that is all you need to put into the file.

But I still suspect the device firmware is what has changed, and not the map. It should be simple enough to roll back to an older version of the firmware, and that really does not require any technical knowledge.

Map Making Support / Re: Updating to Newer Non Garmin Topo Maps
« on: March 21, 2019, 12:38:32 PM »
There really is no such thing as a "GPSFileDepot Map". GPSFileDepot is just a repository for the work of many different authors and there are no standards about how to make or install maps. So you really need to look at this on a case by case basis. As I said, some authors have created installers that automatically remove the old version. This would be required if the new map uses the same ID number, or they would conflict.

If the info on the map page does not address this, then I would just try to install the new version and see what happens. If you only see the new map in Basecamp after updating, then you can assume that the author has automatically handled this. Otherwise, uninstall the old map first. That should remove all the files, but again, there really isn't any standard here.

If you plan to delete the old maps from a card and install new ones with Basecamp/MapInstall, you should be aware that Garmin broke this software last May and still has not fixed it. The current versions cannot install maps properly. It will appear to work, but when you select the map on the GPS, it will be mostly blank. So, if you just blindly delete your old maps from an SD card, you are not going to be happy when you try to install the new ones.  >:(

There is a lot of discussion of this in recent threads here. See this for more information and possible work-arounds: https://forums.gpsfiledepot.com/index.php?topic=4539.0

Exactly what are you talking about? Maps from GPSFileDepot? If so, for starters see what the map author recommends (if anything). Some maps have installers that will automatically remove or replace old versions.

Are you using a Macintosh? Windows? The way most topo maps from here are made, the Windows versions are installed just like a program. Use the Programs and Features control panel to un-install them. On the Mac, the Garmin Map Manager program will allow you to remove a map.

If you are talking about maps of the same state, but from a different authors, you will probably want to leave both installed until you decide that you no longer want the old one. Garmin maps have ID numbers that distinguish them in Basecamp and the GPS. As long as these numbers are different, there is no problem with having multiple maps of the same area. But when you remove a map (as described above), it will be gone and there is nothing to "clean up".

Using The Maps/Garmin Software / Re: Retriving older Garmin maps
« on: March 21, 2019, 08:26:06 AM »
I wonder if the map is different, or if they changed the firmware of the device to display things differently. I am not aware of any place where you can download old versions of the City Navigator map. There was another similar thread here awhile ago, where somebody liked the rivers better on the old map.

You can download/install old versions of the device firmware however. Not sure if that would make any difference.

http://www.gawisp.com/perry/drive/

The appearance of Garmin maps can be customized in a couple different ways however. One of them is the map theme. You will find theme files in the ~\Garmin\Themes\Map directory on the device. They are just .xml files that you can modify in any text editor. For starters, have you tried the different built-in themes? They might help with what you want. You can choose them with the Theme menu on the device. You can make a copy of one of them and then edit to create a custom version.

There is also a little program for this. I don't know if railroads can be customized with a theme however, I have only used them for roads. This program will give you a more user-friendly way to edit themes. I have not used it myself, but the author's other software is excellent.

https://www.pinns.co.uk/osm/theme_maker.html

The other way to change the map appearance is by using custom types. This is an older system and also much more powerful than the themes feature. You should be able to make the map look like whatever you want this way. The same author has a very nice program for this

https://www.pinns.co.uk/osm/typwiz5.html

I (and others here) use this free program to create and edit custom types (.typ files). It works very well, but assumes that you already have a full understanding of making Garmin maps, so probably not a good option for a regular consumer

https://sites.google.com/site/sherco40/

So, there are several options to accomplish what you want without changing the map itself. The thing is, Garmin typically does not use a .typ file with City Navigator, so you need to create a new one to use this feature. And you cannot change the zoom levels at which a feature is displayed by using a .typ file.

That is what makes me wonder if the change you are seeing is the result of new device firmwar? I have a DriveSmart 61 myself, still running the original map and firmware. It shows railroads as very conspicuous striped lines until I zoom out to 1.2 miles, where they disappear. Is this what you prefer (personally, I really dislike this, it just clutters the map and I'm not interested in railroads).

I am running firmware version 3.40. There have been quite a few firmware updates since then! If it were me, I would think back to the point when you most recently updated your map and firmware, then try to find the previous firmware version from the link I posted. For example, the most recent firmware update was 12/20/2018. Is that when the problem began?

To revert to old firmware, you need to access the hidden .System folder on the device. If using a Windows computer, you will need to change it to Mass Storage mode (not necessary on a Mac)

Go to the Volume screen
Press the upper right hand corner of screen for 10 seconds.
The Developers Screen should appear
Scroll down to MTP SETTINGS
Change to MASS STORAGE

Now do this on your computer



Copy the file named GUPDATE.GCD to your computer as a backup. Ths is the installer for the firmware (not the firmware itself). Now take the firmware file that you downloaded and change the name to GUPDATE.GCD and place it in the hidden .System folder, replacing the old file. Restart the devcie and it should ask if you want to install old firmware.

It is always a good idea to have a full backup of your device before changing anything. To do a backup, just copy everything to a folder on your computer (INCLUDING the contents of the hidden .System folder).

Also.... if you aren't comfortable with messing around with this kind of thing, DON'T DO IT. ;)

GPSr Units / Re: remove maps from Garmin GPSmap76CSx
« on: March 20, 2019, 03:31:19 AM »
Yes, there are endless threads on this topic. Garmin introduced an update last May, and it broke the ability to add 3rd party maps. This thread discusses the problemd and has some solutions.

https://forums.gpsfiledepot.com/index.php?topic=4539.0

I would just use Mapsource with a 76csx though. That was the software this old device was designed for, and it still works.

If you are using Garmin's current software for Windows, that's the problem. The current version of Basecamp/MapInstall does not work. You will need to either downgrade to an older version or use Mapsource, Garmin's old software. See this thread: https://forums.gpsfiledepot.com/index.php?topic=4539.0
