GPSr Units / Re: remove maps from Garmin GPSmap76CSx
« on: March 18, 2019, 01:42:18 PM »
In that case, first you must determine whether there is a memory card in the GPS. See page two of the link I posted to the manual above, "To Install the Micro SD card". If there is no card in the slot then there are no maps on the GPS. If you want to install a map (from here or anywhere else) then you will need to purchase a card, as I described in the post above.

If there is a card, then you should determine exactly what kind of mapping it contains. For example, it might have a commercial Garmin marine map and they can be very expensive, so it would not be wise to just delete that. ;)

But if you're sure you don't want the map on the card, just use Mapsource to send a new map and it will erase the old one.

Sorry, but from what you have said, I think you will need more help than I can provide here. Start by reading through the whole manual, that will be a good start. You will also find quite a few videos online if you search for GPSMap 76csx.

Unfortunatley, things have gotten complicated because Garmin's current Windows software (Basecamp) does not work with any of the maps here and Garmin does not seem very interested in fixing this problem. So you should use Garmin's older software, Mapsource.

And, like I said, it's complicated. Sorry...

Using The Maps/Garmin Software / Re: how to display new topos

Check the boxes next to the topo maps on the list that you want to use. The DriveSmart 61 has three built-in maps, the name of yours might be slightly different depending on version

CN North America NT 2019.11 Parkopedia
CN North Ameria NT 2019.11 Foursquare
CN North Ameria NT 2019.11 ALL

The first one is used for finding parking spaces, the second one is POI's from Foursquare. You can leave these checked. The third one is the normal map that you see on the screen and you will have to un-check the box next to it, or you will not see the topo maps (typically - but there could be some exceptions to this depending on the map).

After un-checking the City Navigator ALL box, you should now see the map (assuming you are actually located in the area that it covers). However, I don't know what kind of "trip planning" you want to do. When the City Navigator map is un-checked, you will not be able to calculate any routes. In order to calculate a route, you need a map that contains routing information and I don't think the AZ topo can do this. In other words, it won't be able to give you turn-by-turn directions.

However you will be able to look at the map and mark locations to use with City Navigator. Tap the screen and a little flag should appear where you tapped. Tap the box at the bottom of the screen and tap the Save button if you want to create a favorite (also known as "saved locations" or "waypoints).

If I'm not mistaken, your 76csx is exactly the same as my 60csx, except it a different case that floats? It's dead easy to remove maps from that model, because all the maps are stored on a microSD card inside the device. You could just remove the card, and replace it with another one. Cards are really cheap today - get the smallest you can find, which will probably be 4gb. An old device like yours really doesn't need anything bigger. Then you can keep the old card as a backup, in case you ever need your old maps again.

But if you don't want to do that, set the GPS for USB Mass Storage mode - see page 41 here

https://static.garmin.com/pumac/GPSMAP76CSx_OwnersManual.pdf

Then connect it to your computer. It should appear as a disk (may take awhile). There should be a folder named Garmin. That folder will contain the map - I would only expect one file to be there, named gmapsupp.img. You can delete that if you're sure you will never need it again. Or you could save a copy on your computer.

One other thing about your old GPS... if you use Mapsource, Garmin's old software, the next time you send maps they will automatically erase whatever maps you currently have on the device. So if you are going to add another map, it will erase the old one anyway.

Most likely, the problem has nothing to do with your Montana. If you used Basecamp/MapInstall then that's why the map doesn't show. The current versions are broken and cannot send maps to a GPS. The condition you describe is exactly the symptom of this problem.

GPSr Units / Re: GPSMAP 60CSx advice...
« on: March 17, 2019, 03:49:17 AM »
Glad you got it working. But if you just read through some recent threads here you would have learned the problem is that MapInstall is broken and the current version cannot send a map to your gps properly. This problem has existed since Garmin's last update in May 2018, and now they have discontinued it. However, recently there has been a sign that they are going to do one final update to fix this problem.

See this thread for discussion of the issues:https://forums.gpsfiledepot.com/index.php?topic=4539.0

And yes, Mapsource is the easiest fix IMO and that is the solution that I and others have been suggesting. I think Mapsource has always been the best software to use with an old device like the 60csx in fact.

Wouldn't it be nice if the GPSFileDepot forum software supported images wider than 500 pixels? I mean... it's 2019.  ;)

LOL - I suppose you have a point there, but it can help make a boring drive more interesting. :)

Also, since some people may not understand what "raster imagery" is, I think that needs clarification. It's a map that was created from an image. The image can be anything - such as a scan of paper map. So this is a way to use topo maps on the DriveTrack 71, and they work very nicely. Here's an example of a classic USGS 24k topo maps




And here is a 19th century topo




This is a modern topo map that I created




These examples are all from my site, but there are other good sources of free raster topo maps for just about any location. You can use the free Mobile Atlas Creator program (with Windows, Macintosh and Linux versions) to access these maps and convert them for the DriveTrack 71 (and dozens of other apps/devices). I have just updated my tutorial for this - see the following link:

https://boydsmaps.com/mobile-atlas-creator/

Mobile Atlas Creator includes built-in access to free topo maps and aerial imagery from the USGS in addition to Canadian maps from Toporama. See Appendix A of my tutorial to learn how to access  "classic" USGS paper 24k topo maps. And these maps will work on all of Garmin's recent handheld GPS devices, not just the DriveTrack.

Now, Popej and I have had this discussion before, and I don't think he likes raster maps very much. ;) That's fine - they have their weaknesses (such as large file size, inability to search for features, etc). But they also have their strengths. Here in the US, many people consider the classic USGS 24k maps the "gold standard". And they also work across a broad range of apps and devices

The DriveSmart 61 (same hardware as the DriveTrack 71) is noticeably faster than any Garmin automotive model that I have seen. Going back a few years.... in 2010 I had a Nuvi 3790 which was Garmin's first glass screen multi-touch device. Nice unit, but definitely underpowered. Then I got a Nuvi 3550 in 2012 and that was much faster. I thought it was great, until I got a Dezl 760 in 2013 and it was faster still. The DriveSmart 61 blows it out of the water, in spite of the fact that the screen is 1024x600 and the Dezl is only 800x480. If you want to test your GPS, try this map. I doubt that anything older than a DriveSmart 61 will even work.

https://boydsmaps.com/lidar-in-the-pines-sd/

This is my system of putting raster imagery in an .img file. It's a simple grid of 48ft ft x 48ft (15m x 15m) polygons with a road and POI overlay. It works fine on my DriveSmart 61. A bit slow to initially render a view, but it can keep up at highway driving speed and has never crashed (although it disappears if you zoom out farther than .2 miles). This same map just crashes my Dezl 760. Didn't bother trying it on any of the older devices.

But the DriveTrack 71 renders raster imagery pretty fast - a lot faster than my Montana 600 for example. Initially it has to render it tile by tile, then as you drive, each tile is updated as needed, so there are always some small areas in the process of rendering at highway speeds. The farther you zoom in, the faster the screen updates (since there are fewer tiles). With 1-meter/pixel imagery, initial map rendering is very slow at a zoom setting of .3 miles. At 300 ft zoom setting, rendering is very fast. Anyway... for Garmin, it's fast. But, admittedly not as fast as raster imagery on my iPhone 6s Plus. ;)

Here's a screenshot from this morning, driving 50 mph with this map, performance was fine: https://boydsmaps.com/new-jersey-2012-orthophotography/



I used a "custom map" (.kmz file) for this, instead of Birdseye (.jnx). Actually, rendering speed felt about the same as birdseye. My understanding is that .jnx files can contain 5 zoom levels, but I haven't tried that yet (.kmz maps can only have one zoom level). So that will be my next test - if they really support multiple zoom levels, that should speed up rendering considerably (at the expense of file size). The .jnx files I have made so far only have a singe 1-meter level (this would be level 17 if using a format like .mbtiles).

BTW, if you enable City Navigator at the same time as raster imagery, there is very little impact on performance. I really only notice the difference when making a 90 degree turn, which causes a big screen update.

This device is identical to the DriveSmart 61, except it can use Custom Maps (.kmz files) and Birdseye imagery (.jnx files). Then there is a separate module for dog tracking which can be disabled by putting the device in Automotive mode. But topo map rendering is exactly the same as any of the Drive or Nuvi series from the past 5 or 6 years. I guess Garmin thought it would be more attractive if they bundled it with the 100k topo and called it "compatible".

I have been making topo maps especially for Garmin automotive devices for a long time, and many of the issues can be solved by using non-standard custom types. There are screenshots from a DriveSmart 61 here, and map rendering is identical on the DriveTrack 71.

https://boydsmaps.com/boyds-map-of-new-jersey-2018/

So if someone wants vector map rendering in the style of a Garmin handheld, they will be disappointed with the DriveTrack 71. The strength of this device is raster imagery, and that looks fantastic on the 7" screen at 1024x600. It can use 400 custom map tiles, and you can individually enable/disable each .kmz file.

But, since it includes a Birdseye subscription, I am using .jnx files and they are great. Much faster rendering than .kmz, support for 5 zoom levels with 50,000 tiles each and file sizes up to 4gb. I am using OkMap (you need the paid version for $22) to create the .jnx files. With an active Birdseye subscription, you copy the .jnx files to the GPS and then drag them to your collection in Basecamp. Now you have to delete the original file from the GPS and send it back again with Basecamp, where it is "authorized" by contacting Garmin.

One nice little feature is a map setup shortcut in the tools screen. This makes it easy to enable/disable maps and imagery without digging through menus. So the device works nicely with multiple layers of vector maps on top of raster imagery.

You can't disable the basemap (like all automotive devices) and the low resolution roads appear on top of your raster imagery, which is really ugly. So I just made a big, black "blank map" to hide it.




I used draw priority 31 for the blank map, so it will also hide City Navigator. This gives you the route line and all the regular automotive features without anything else to clutter the raster image.



Anyway, I'm really happy with this device and think it offers a lot for anyone who makes their own maps and wants to mix vector and raster imagery.

The 2797 is nice, I have a Dezl 760 which is the same 7" hardware platform but different firmware. I used it for a number of years and liked it a lot. But it can't do this like the DriveTrack 71.  ;)

BTW - the DriveSmart 61 has an interesting "cousin", the DriveTrack 71

https://buy.garmin.com/en-US/US/p/601687

I just got one of these and am very impressed. The hardware is identical to the DriveSmart 61, the only difference is the little label hidden under the ball mount. But the ability to use raster imagery (BirdsEye and "Custom Maps") is terrific. As a map-maker, this gives me something I've always wanted - a big-screen automotive device that lets me mix raster and vector imagery.

Definitely worth a look, especially if you were considering the DriveSmart 65. The DriveTrack 71 costs $130 more than the 65, but the included 100k topo would cost $100 and Birdseye would cost $30 if purchased separately. So if you want those maps, the cost is actually the same.

I have started a thread here with my first impressions and screenshots:

Well it's always possible that there is just a problem with that specific map - I have never used it. To troubleshoot, you could try removing all the maps but the Arizona Topo and see if it works then.

Also, confirm what version of MapInstall you are using. If it is 4.2.0, then that is the one which does not work.


29
BTW, Garmin just updated the Macintosh version of Basecamp/MapInstall last week. I just updated my Mac and the new version of MapInstall works properly. It is also a 64-bit application now.

Hopefully this means a new PC version is coming soon. :)

I never upgraded, so I still have MapInstall 4.04. But I don't see any way to "uninstall" that either (aside from deleting the folder. But, FWIW, you will find archived old versions here

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

Personally, I would just use Mapsource. You can download version 6163 here. It should recognize all the maps you have in Basecamp.
