OSM maps on the 1030

I have the supplied USA maps on mine and I loaded an open fiets map of Australia. These show up in the menu.
I tried to load a Garmin Australia map which I have in Mapsource (and basecamp) but these won't show up in the menu but I can see the maps have loaded if I connect to a computer

Unicode OSM maps don't work on all Garmin devices. You can use maps with ASCII codepage only :-(.

https://openmtbmap.org/garmin/unicode-maps/
or
https://openmtbmap.org/garmin/englis...language-maps/

Tiles are for PC/MAC only, on the Garmin image files are needed. (*.img)

ok -- to avoid any confusion let me add some detail (I'm using a Mac normally, but the same thing happens on a PC .. this is just the mac perspective in the discussion below)


#1 This SD card *works* on the 1000 so I don't believe this isn't an ascii UTF-8 or any problem like this.

#2 Putting the .IMG files in /Volumes/SD/Garmin does not work
#3 Putting the .IMG files in /Volumes/SD/Maps does not work
#4 Putting the .IMG files in /Volumes/SD/Garmin/Maps does not work
#5 Putting the .IMG files in /Volumes/SD/Garmin/CustomMaps does not work
#6 Putting the .IMG files in /Volumes/SD does not work

#7 Using the ridiculously complicated "official" process of using Garmin MapManager + Garmin MapInstall to load the maps first on the laptop then do whatever it does to take hours finally producing a gmapsupp.img in /Volumes/SD and pronouncing it "done" This also does not work

What does the GarminDevice.xml (? not quite sure of the name and I can't look at one of my devices at the moment) on the 1030 say it's looking for? They normally tell you both where and what name (*.IMG? gmapsupp.img?) it's looking for. Does the same map work on internal storage?

I suspect you may be breaching the maximum map tile limit. I can't find a relevant FAQ for the 1030 but this gives details for the 1000

With respect .. the card WORKS on a 1000. I've been doing this for years. Though without knowing the map-tile-limit I suppose its possible for it to be smaller, seems counter intuitive ..



Also your article is related to the storage of the internal device, it specifically tells you to use a SD card for "larger" maps [ emphasis mine ]

While considering memory limitations, another limitation is the number of individual mapping segments. Roughly 5250 map segments[SUP]2[/SUP] can be transferred to the Edge. The Edge is pre-loaded with detailed mapping called Open Street Maps (OSM) as well as a Cycle Map, a base map and a digital elevation model. (DEM). The preloaded maps consist of approximately 2300 mapping segments (Approximately 1000 for Europe). It is suggested to transfer additional mapping to a second microSD card to accommodate the additional segments.


Typically when traveling I'll put the *.img file of the country on the SD card .. That has worked for 3+ years on the edge 1000 .. I'd keep multiple SD cards to with different countries handy to avoid running out of tile space .. though I never have doing that method

Well yes while it would be nuts if the tile limit decreased when compared to the 1000 it's entirely possible pre-loaded maps might be larger on the 1030 so whereas the card would work on the 1000 it wouldn't in the 1030. You could check to see if that's the issue by either removing some maps from the card or more easily just change the .img on some of them to .xyz or anything else you wish. Note the tile limit on any Garmin device applies to maps both on the device and any installed card.

I breached the tile limit on my 810. The map still worked but the odd random tile would not be processed so you would have a blank area on the map.
I do the same as Dallas and have split my maps onto a few sd cards.
I briefly had a 1030 and my existing sd cards worked normally in it.

Looks pretty close to the same in both devices ... I've never been able to figure out how the Garmin devices know (or prioritize) to look to an SD card vs the in-device memory and have just assumed they look for a somewhat identical filesystem layout

anyway -- the relevant sections are below

this is on the 1000
