My GPS won't directly download from S&T either. Unfortunately, I loaded Mapsource on the same day as S$T, since I just got a 60CSx a couple weeks ago. Unfortunately, the Mapsource did not come with an unlock code for the maps, and my first email to Garmin customer service was less than helpful. But S&T looks good -- similar to Google Maps and pretty intuitive.S&T will not see the StreetPilots directly. Their USB interface does not have a COM1 or COM2 driver that S&T expects to find. Export the GPX from S&T and load it into Mapsource, and transfer from there.
