I don't have a device yet, though I am planning to getting the 64st. I bought a 24 K map and would like to download it to Basecamp on my computer so I can start planning and exploring the map, to later be connected to the device when I get it. However, I can't seem to find a way to download the map and then import it into Basecamp. The email I got upon purchasing tells me I must use the Express app and it doesn't do anything until I connect a device. Is there a way to get the purchased map into Basecamp prior to receiving my device? Thank you.
