I'm a total newbie at this Map down and uploading. But I just discovered something that may save others a ton of time. I somehow lost all the maps I installed to my Garmin 60 csx. Probably due to canceling a upload to the unit and unplugging too soon. Needless to say I was bummed since each state topo took an hour or more. I am now reloading everything onto the card using a high speed card reader and it seems to be way faster than transferring directly to the gps unit.. I mean just a few minutes instead of more than an hour.. Probably a no brainer for you veterans but thought I'd mention it for others.... [Mac OS X, Garmin Map install, Garmin map manager ]
Yes, USB 1.0 is dog. :P The newer models have USB 2.0 however.
You might find this to be a double edged sword...
If I load maps directly onto my GPS, it's a little slower to transfer, but the GPS Starts up fast.
If I load maps onto an SD Card, the transfer is fast, but the GPS takes more time to start up, while loading maps from SD Card.
Just an observation...

You have to load maps onto the SD card if you have a 60csx like Solarmon. It does not have any internal memory for storing maps.
