I have a Garmin eTrex Vista C which is very nearly the same unit as the 60C/CS, softwarely speaking, except smaller, slower, different (internal) antenna, and less memory. It also only has a USB connection, not Serial/USB. It seems that any of the Garmin units that have serial ports, you can connect to the mac through a serial port or a serial-usb converter like the ones from keyspan (which have nice mac drivers). But if you plug the USB connection from the garmin into the mac VPC6 cannot use it. Basically it shows up in the USB device list as "unknown device" and you can select it but it won't stay selected and never becomes visible to Windows. If anyone has gotten a Vista C to work, I'd love to hear how. I'm using Windows 2000 in the virtual pc.
That would be really nice if VPC7 corrects this problem -- right now I'm stuck using an ancient dell laptop to do the mapsource stuff, not my shiny beautiful powerbook =)
