Has anyone been able to read from or write to a Garmin data card connected thru the data card programmer? I have four Garmin devices that I can connect to MapSource running on Windows XP thru parallels using either the USB or serial port connections and they all work fine. The data card programmer is acknowledged by MapSource but I can neither read or write the card. The card is OK as I can read and write to it thru the serial port when it is plugged into a device. Answers from Garmin tech support were the usual "wait for the Mac version".
