Garmin map question
 

I was going to buy the gamin touring plus, but found a used gamin 810. From what I read it does everything the touring plus does except for inventing round trip rides for you, from where you are and putting in how many miles you want to ride. And it comes preloaded with city maps, the 810 has to use a SD card, at added cost but does far more. Mine unfortunately is without that SD card. My question is if you buy the SD card from garmin, is it updateable? Can I find a used SD card? How does this all work?

If you buy a SD card with maps from Garmin it's not up gradable.

You can buy an empty SD card and then use free Open Street Maps on it. I use "Openfietsmap Lite" from Free worldwide Garmin maps from OpenStreetMap

Garmin Owns Delorme now , Delorme has made maps, atlases of states, and of course maps as software. check out the Delorme products too..

{I own a couple printed Atlases ) Maybe you can fill an SD card from your computer downloads? newest cards hold a lot..








...

This is what I did with my Garmin Edge 810. DC Rainmaker has a helpful blog post on how to do this.

Agree, just buy a cheap SD card, throw it in, then follow the DCRainmaker directions. It’s very easy and gets you maps as good as what Garmin would sell you. Note that the 810 came loaded with useless maps with no detail, Garmin expected users to buy maps from them, but allowed the OpenSreetMaps to be used as desired, which is what everybody does.

It seems that Garmin isn't selling current versions of Delorme digital maps.

At this point, they'd be duplicate products for Garmin.

It's not likely that they would work on the Edges (or other Garmin GPS units) anyway.

There are numerous sources of free OSM maps for the Edges. It's a well-known process.

Many (if not most) bought the 810 with a bundle that included the map (making the map cost about $50). One problem is that you have to pay to get updates.

The "useless map" is the world basemap. It is somewhat useful for areas where you don't have detailed map coverage. It also makes screen updating faster at low zoom levels.

Garmin didn't really allow the OSM maps to be used. They had no choice.

What happened is that people reverse engineered the img file format years ago. They wrote two programs that take OSM extract data to create img files.

Garmin sold people maps in this format (the topo maps might still use this format). Preventing units for using this format would have really annoyed their customers.

Garmin has a new img format (called NT) that hasn't been reverse engineered.

The Garmin "City Navigator" (CN) maps (what Garmin sells) don't have cycling-specific information (like cyclepaths). The OSM maps often do.

Garmin now includes the OSM maps on newer units (at no extra cost).

That works because it gives cyclists more appropriate maps and the OSM maps don't cost Garmin anything (unlike the CN maps that cost Garmin a lot of money to produce).

FYI, it does "back to start" navigation. You can go out and ride following your whim, and have it route you back to your car when the time comes. It's not exactly the same thing, but it will work, you can confidently explore new areas and not get lost.

I played with this option yesterday on my Garmin Edge 1030. Had a few "fail to navigate" errors before it settled down and worked okay. However I was on a mountain bike trail so that may have been an issue.

Still when it worked it was handy for at least letting me know how far I had to go. I really didn't need it for navigation purposes but can see it being a handy feature.

Begs the question where the trails even plotted on any map that the GPS would use to navigate ?

I could not possibly use navigation at my local park, the trails dont exist, for the most part, as far as Garmin or RWGPS are concerned.

Anybody can add/update the OSM map data.

Keep in mind that the Edges are intended to be used for cycling (they might not be able to use paths that are not indicated for cycling).

+ 1 The key to Open Street Mapping products :)

I had forgotten that. I've no clue how to add a trail system to OSM, but will look into it.

It takes some practice. Make small changes starting out. See how other similar things are coded.

"Footpaths" are paved pedestrian ways (they might allow cycling but are primarily for walking). You can use a wheelchair on them (usually).

"Cyclepaths" are cycling roads that your grandmother would be able to ride on. (They might allow walking but are intended for cycling).

Hiking trails are "paths" (not "foot paths").

MTB paths are "paths" (not "cyclepaths").

Paths where cycling is allowed should be tagged "bicycling=yes". Ways where cycling isn't allowed should be tagged "bicycling=no".

Roads are assumed to allow cycling (which means they don't need to be tagged "bicycling=yes").

Well, cool !. Will look at one of our local parks.

Thx

Garmin map question, March 2018
 

Have edge 1000...old one. Haven't engaged it other than turning it on and just riding for years; forgotten any deeper manipulations and so many bugs originally, one finds something that works and just keeps with it [not learning the fuller capabilities of said device; pretty typical with all modern devices I think and pretty scary with on-line banking, ha]. Simple search of this forum turns up dated threads and not the info I need. Soo...

I Plan a trip to Europe this summer. Would like to upload a street map of Europe to the edge 1000, especially through major cities. Is the dcrainmaker site still the best instructions on obtaining cross continent maps [how extensive are the base maps included on the original 1000 anyway, 2015 vintage]. Garmin website offered nothing useful for me that I saw and not sure of what works or not anyway.

Guess I've just used the basemap all these years; not sure. I turn the device on, and I get a 'Unable to Unlock map' notice before it goes to the main menu. Hasn't affected my ride...so just ignored it all these years. Can still navigate, load bike club maps and such.

I'm assuming I will have to load a street map of Europe to use it there.

I am not familiar with your Garmin or with your other computer resources. So, not sure if this would help. I loaded these maps into my Garmin but I have a different Garmin and I use some vintage software on my computer.
Europe - OpenFietsMap

Instead of the giant file, I loaded the individual smaller files (all but one are still big at over a gig) lower on the page.

I have not used these yet, I can't say if they can be used with routing software or not.

DC's instructions are easy to follow, you can also Google "how to download and install OpenStreetMaps to a Garmin 1000".

Yes you will likely need OSM maps for Europe,

The 1000 comes with detailed maps for its "home" region. Those maps are based on OSM data.

You can get free OSM maps from other sources.'

If you have a smartphone, you can use Galileo, OsmAnd, or Maps.me (free) to download maps to your phone before your trip. You don't need cell service to use the maps (you are using your phone as a small computer that has wifi).

Yes, you need maps for where you are going. It's free and easy enough to do.

You probably don't need maps for all of Europe.

I download maps for the regions I'm actually travelling in. That makes the files much smaller and makes it reasonable to get up-to-date maps.

OSM maps that are almost a year old.

There are more current sources of maps. They also let you create maps for custom regions (covering just what you need maps for).
