    OK, I'm old school but soon to move up in the GPS world! In ancient times loading map sets to a Garmin with internal memory via serial port was a slow drawn-out process. Part of the reason was that it always started from scratch even if only one map segment was to be changed. I understand the USB interface is faster and a card reader faster still.

    My question: In the newer units that can use a flash memory card, is the process the same? Is the old map set 100% erased and loaded anew even if only 10% of the data is to be changed???

    Yes!

    The USB connection makes this much faster and large SD capacities make the requirement to do it much less frequent. It really isn't an issue anymore on the Garmins.

    Is the 60CX that much faster via the USB? My 376c is not that bad, but certainly not quick.

    When I get mine in a week or so, I am going to try loading the SD card via the SD reader on my laptop and see if that works. I'm crossing my fingers.

    Is this true even if you computer can read the SD card as a storage device?

    The comparison was between a serial interface to the GPS and a USB connection. If you are writing directly to an SD card from Mapsource that will probably be faster than writing through the GPS. How much, I don't know. I find writing through the GPS fast enough for my purposes.

    I loaded about 850MB of Topo onto a 1GB card inside a 60CX the other night. It took about an hour or so, but I wasn't paying close attention to the time. It was definitely faster than the olden days.

    You can load the whole US CN8 to a 2gb card in about 50 minutes IIRC.
