Noob situation alert. I've downloaded OSM Topo maps onto a formatted SD card and the maps can be seen and displayed on Basecamp and the SD card is also 'seen' by Garmin Express and shows the available disk space when the XT is plugged in. However, my XT doesn't see the card at all.
I know it's me and it's something I haven't done (obviously) but I'm wondering if anyone else has had a similar problem and can advise what to do next?
