Thread: Nuvi 3590 not loading maps from SD Card

1) Try a different microSD card, sometime a Garmin device will get fussy about one card but will accept another with the same map without problems, even if the second SD's the same brand and size.

2) Reformat the microSD in FAT32 and then reinstall the map on the mircoSD with MapInstall (NOT MapSource, it will give errors converting modern NT/U map data). Use the official SD Association format tool rather than the built-in Windows formatter:

Thanks for the suggestions.

I have oredered another microSD card to see if that helps at all.

In the meanwhile I reformatted the existing card and re-installed the map using Garmin Express (the map had previously be re-installed using MapInstall) but still couldn't be read on the Nuvi.

I don't know what the signal path is on the Nuvi but when the map can be read on Garmin BaseCamp via the Nuvi it must be lifting the data off the card to send via the USB computer connection but for some reason it's own operating system isn't able to access the same data.

When the new card arrives I'll format using the SD Association tool (thanks for the link) then report back.

Thanks
