![]() So the Garmin Express software basically deleted the original TopoActive map and Worldwide full Basemap that was on the device and replaced them with demo versions.Īnyway, I just purchased a new microSD card which will arrive this evening and I will be trying it out to see if the issue was with the card. ![]() However, after 3 hours of Garmin Express writing them to the microSD card via the device, on turning on the device the maps were nowhere to be seen and the only maps available for enabling/disabling were now the "Worldwide DEM Basemap" and "Garmin DEM Map EU 2017.20". Locate the map and data memory card slot on your device ( Device Overview). The device supports microSD memory cards from 4 to 32 GB. It said they were too large for the internal memory and so would go on the microSD card, which they did. You can purchase memory cards from an electronics supplier, or go to to purchase a memory card with pre-loaded Garmin ® mapping software. I also plugged the device into my MacBook Pro and used Garmin Express to update the TopoActive maps that were already installed to version 2019.20. The map did not show up in the enable/disable maps option screen. I downloaded the OpenTopoMap for British Isles from and put it on the microSD card in a root folder called "Garmin", then inserted the microSD card into the device. Thanks for your comment and pointing me to that thread. So what do I do now that the stupid Garmin Express software has deleted the TopoActive maps from the device memory and installed a huge version on the microSD card which the device doesn't seem to want to read? I've also tried putting the British Isles version of the OpenTopoMap on the microSD card and that doesn't show up either. Well now my eTrex 30x doesn't show any maps besides the BaseMap and a "Garmin DEM Map ED 2017.20"! It's like it isn't reading the microSD card at all! It seemed to detect the microSD card fine and decided to change the install location of the TopoActive maps from the internal memory to the microSD card, and downloaded a significantly larger update than it was going to when I didn't have a microSD card installed (6-something GB vs 3.7 GB). IF that's the case you need to delete them, create a primary partition, format it to FAT32, and re-copy your maps.I just got a Garmin eTrex 30x and I installed a freshly-formatted microSD card (8GB, SanDisk) into it, and then plugged it into my MacBook Pro (macOS 10.15.2) and let Garmin Express update the TopoActive maps (Europe 2019.20). So the tip here is: try to see if your SD card has been partitioned to have EXTENDED partitions or LOGICAL partitions. ![]() K masivnmu ruen pracovnch mst se chyst vce technologickch. Last update on / Affiliate links / Images from Amazon Product Advertising API. Linux saved my day and now I can navigate american maps with a european Nuvi. This problem occurs because Garmin devices that are formatted with FAT12, FAT16, or FAT32 file systems are not recognized as mass storage devices by a computer or device that's running Windows 10. ![]() How I found this out is when I got home and tried to manipulate some map images. Several tools on windows like Windows' disk management tool and MiniTool's Partition Editor create nested partitions. I struggled for days with my Garmin and different SD cards from all brands, qualities, speeds, specs.įinally I found out that SD cards must be very strictly partitioned: you must have only 1 PRIMARY PARTITION on the card. Any ideas? I tried to download the Mexico maps (1.25 gig) on the Nuvi internal memory but it says it is too big.hence the SD card! Can I create more space on the Nuvi, paste the Mexico maps and foget about the SD card? Thanks for your help! My computer reads the SD card alright but the Nuvi doesn't! I also have a Nuvi350 and it can read it's SD card just fine. Hi! I have a Nuvi250 and I just bought a SD card to put Mexico maps on it.
