I was looking at Garmin Express to see about getting the Europe maps that I need. I thought I would delete the Mexico and other areas as a test. But Garmin servers are not allowing any activity. Now this kinda reinforced my concern about Garmin screwing up my device.

So my idea is to move the map files to a micro SD card and then obtain maps from Openfiet or BBBIKE.

My question is how do I identify the map file on my Garmin?

If you need more information let me know.

Thanks
