    The 2 gigs are SD. I think anything bigger is SDHC. I don't know what the difference is but they won't work in some devices.

    This arrived over night from Garmin:

    Dear John Bunce,

    Thank you for contacting Garmin International.

    The largest SD card that is supported by the Colorado series is 4GB. Just get a standard 4GB card, not the high-speed ones.
    With Best Regards,

    Found this on a Wiki for the colorado.

    http://garmincolorado.wikispaces.com/General+Information

    G13.) What is the largest SD card that the Colorado will support?


    Garmin claims support for a maximum of 4GB SD cards in the Colorado, but 8GB SDHC cards have been verified to work in the Colorado.
